Interview was great! Hardest part is being disciplined to do Z2. Fighting the ego when a rider passes you. I went from doing 19 km/h at Z2 to 30km/h at the same Z2 heart rate in 4 months. Takes practice. GCN training needs to come out with some scenic 90minute Z2 rides that we can follow on the turbo. Record the presenters doing a Z2 easy ride from the bike and release it once a week. With them talking and make it fun. Similar to this by SAFA Brian ruclips.net/video/nbsWYYtOcFk/видео.html
This information has no relevance to me; I don't train, I just ride my bike in the park. But it sounds terribly complicated. And it brings back memories of other doctors coaching other cyclists, frankly.
I used a 90% Z2 training plan for ultramarathon running and it absolutely works. My aerobic endurance has never been better. When I picked up cycling, I carried over this type of training and it has worked out really well on the bike too.
I have stage four cancer and was told that I had 4-6 months.. 10 years ago now. I am a very old roadie and extremely interested in this type of interviews/ research. I honestly believe that my bike has kept me alive. Great interview
It is known that cancer cells need high amounts of glucose in order to lie and grow and once you restrict glucose, they may stop growing, so yes, practicing endurance sport helps the body eliminate the excess of glucose due to today's high carb diets.
@@AR-lz2br It's not as simple as you state. Healthy cells also require glucose and there's no way of telling our bodies to let healthy cells have the glucose they need, but not give it to the cancer cells.
@@james5150 I'll be sure to check those. I'm just now diving into these subjects because I don't want to make in cycling the same mistake I did in running: too hard too often. Cheers.
I worked under Dr. San Millan for 5 years in his Colorado lab and also hung on to every word he said. He is brilliant, making a huge impact with his research and great at breaking down and explaining complex physiological concepts!
This really explains why when I was commuting by bike I was always so much stronger/faster than when only training via turbo with occasional outdoors. Zone 2 always seemed to be the right intensity for the commute. Of course, I was also 10 years younger at the time...
Yesss exactly that. I was so slim in Japan, cycling to work in a shirt, and this only going zone two.. But regularly, and I think having to work, rather than sitting in the sofa, also maintained my metabolism
especially riding in traffic. the constant braking, slowing down, ramping up again, full stops then oops forgot to switch to the lower chainring then the traffic resumes, it all adds to the training. the bumps on the road? additional plates to your bar in gym terms.
And it really explains why when I was commuting by bike I always was tired and often getting cold. Been riding in Zone 3/4 all the freakin time, seemed right back then;)
As a reminder. Your Zone 2 will change as you gain endurance, so don't think your giving up fitness. Be positive about your outcome from a 3 day focus in Z2. You will see results! Keep it up GCN, we need these interviews.
I've been following this training regime for 7 months. Yes my zones have changed positively, but whilst I have been using the 80/20 idea, I've lost 11 watts of power and my strength has decreased terribly. Personally I think as individuals we should be looking at "what fits me best". Sorry to put a damper on the discussion.
@@47Seagull then your nutrition or recovery might be off. How on top of your nutrition are you? Are you taking supplements like magnesium, Omega 3, zinc, vitamins, etc? Enough protein and carbs? Do you fuel during your workouts? Do you stretch daily? Sleeping enough? Honestly all these points unlocked crazy fitness for me in terms of endurance and strength training. Injury free too so far. One thing I did notice with higher volume / lower intensity training is you gotta fuel up before, during and after your sessions.
this might be a weird question but how do you measure when your zones have changed? how do you determine that or what is even meant by that? I come from running so not completely uaware of the concept but just don‘t get that
I have to be honest and say that I haven’t been a fan on GCN content for a while but this interview of absolute gold. Well done Simon on great questions, style and a really good summary at the end. One of the best videos I’ve seen on RUclips. 👏🏻
As a novice rider that enjoys cycling SOOO much as it is the catalyst for my weight loss and maintenance for the last three years, I appreciate your sharing this VALUABLE information and presented in a way that my novice brain can put it to use. A+++
I suck, but I'm healthy and feel pretty darned good. I once read elite level athletes only hit it hard once a week, the rest is training like this guy says. Best gains in lifting are ay 70% of one rep max effort. Mike Metzler worked some good suff on not overtraining in bodybuilding back in the 70s-80s
Time crunched, pushing 50 weekend warrior here. This was the single best GCN video I've ever seen. Zone 2 is a critical oversight in everything I've ever done and just from hearing this I believe this will have the single biggest impact on my training. Thank you!
Its worked for me. Ive ended up doing 3 local group rides per week, and at about zone 2 for 2 hours or so per ride..........and I kept thinking this cant be doing much for me. But its fun and I kept doing the rides. For well over a year and a half. Coming back from getting a new knee put in, and some years off due to the knee. I wasnt showing much improvement on the occasional climbing ride.............but then something happened, and my pace now keeps picking up, and up. I'm going better overall than I was 30 years ago. I'm 65 and I keep ending up at the front on climbs ,some riders in their 40's and they are busting a gut trying to beat me. Obviously we arent racers. But I'm always competitive no matter what, I'm enjoying be able to just pick up and go on climbs, and cruise at a good pace on flat. 22mph is fine for a long time. Its all about the fun.
Iñigo's words absolutely match with my personal experience. I was freaking out about getting faster and doing all that high intensity trainnings, but got into a plateau. Then I saw some other guys in the internet saying you could improve your performance by taking it easier. I tryed it. Guess what? It worked. So now I always do some Z2 trainings.
This is the only thing I miss about my daily commute and not doing it anymore. 5 days 1hr per day Z2 just to get to work. It was a great free workout, the fitness level was so high with this as a base.
@@james5150 Attia, Endurance Planet, Andrew Huberman, and of course Dylan Johnson (especially for despite backwards cap Dylan take on things) are my go-to podcasts for related information. I missed the one you mentioned so that going up on my playlist today! 🙏🏻 thanks.
Definitely, we all know cycling and exercise are healthy for you but when you learn more about how healthy and how to make the most of your time it makes all this exercise even more motivating 🙏💪👍
Having done my fair share of overtraining, I appreciate what this guy is saying. There is nothing worse than putting more energy into training and seeing results get worse. Not to mention the night sweats and low quality sleep that comes with overtraining. What's interesting about what he's advocating is how similar it is to the way it was suggested that riders should train in the 80's.
I did zone 2 last offseason to condition for mountain biking because I was recovering from shoulder surgery. My second ride of the season resulted in a PR. Basically I was conditioned equally to the end of the season.
This is the way I train. I ride a 'Slow, Steady distance' from home to my son's home 90 miles away. A small amount of soreness but no D.O.M.S. I share out grinding ( uphill ) and spinning. BTW, longest gear on my touring bike is 75 inches, and when it's loaded, its 32 lb. I manage my intake and rest at cafes along the route. Essential to stretch out before getting going. PS. I'm 62.
@@acanfield87 Well, they also called it "LSD," "long slow distance," back in the '70s, something like the first 1000 miles after the winter layoff to burn off the fat and get everything working.
Yes! I’ve been taking ‘LSD’ since I first started riding in the 80’s 😮! I think I’ve been practicing/benefiting from Zone 2 training for years and not aware of it. I’m 68 now 😂
In rowing this is talked about as base speed training. It's been well recognized in the community that base speed training is essential to get faster. Glad to see this is actually supported.
Weirdly enough I find it difficult to reach Zone 2 when rowing (unless I push hard), which seems counterintuitve given rowing engages more muscles than cycling. 😊
It used to be the basis for many UK club rides in the past, youngsters were advised "little ring until Spring" and "Winter miles mean Summer smiles" but it became unpopular because it requires patience and consistency - riders with egos thought that winning town sign sprints in January was important. When HIIT training and Zwift soared in popularity these longer rides were maligned unfairly as 'junk miles' but we now know that the polarised method is still valid for recreational and amateur cyclists as well as professionals. I've been doing this for a while now and find zone 2 type riding is more fun and I can enjoy the ride and my surroundings much better if I'm not so focussed on making every ride a hard one in an attempt to get fitter.
I've made some progress in the last two months by putting most of my time in the saddle in zone 2. I notice the improvement on sprints over short hills. Feels good to blast over my favorite bumps faster with less thigh burn. This video confirms what I'd suspected. BTW, I'm 66.
Good on ya, I'm 65 and giving it bloody hell. Ive never been better than mid to back of pack on climbs. Now I'm going better than when I was 30. (I wasnt fast then) It really surprises me, I seem to go better every ride out. Almost 2 years of around zone 2 group rides seems to have worked..it takes much time to make it happen. For me anyway.
Fascinating to draw the link with metabolism and cancer treatment as well as his statements about how nothing has changed and we need to push into new lines of thought. So I can tell my non cyclist friends who shake their head at me when I get excited about a race that pro cycling is contributing to cancer research. Thank you Dr. San Millan. Go CU!
Yes been doing alot of reading lately on how to reverse types diabetes , best diet etc . Fasting has come up alot . There is a lot of hype around, even with Dr making false claims on utube . I watch nutrition made simple lots of science information on healthy diet. But yes there is evidence on how fasting can slow some cancers and speed up other cancers . But no doubt an active life style , healthy bmi bodyweight low calorie intake and healthy foods can make a real difference on cancer and diabetes
Fantastic information. As a cancer patient, I found the section on the causes of cancer particularly informative. I also liked the information on Zone 2 training. That is something I will do once I am back on my bike. Dr. San Millian is a brilliant, multi-talented man.
Was planning on making this winter predominantly Z2 after overtraining the last two winters. Glad I saw this as it was getting tempting to just go hard as that's so ingrained.
That was one of the best videos you guys have done love it when you talk to experts and get more into the science behind health and fitness on the bike
Great interview! I had already listened to Iñigo in the Peter Attia podcast, and I highly recommend checking those out if anyone is interested in the details, but this one goes straight to the main points of Z2 training. Iñigo is also the guy who introduced low intensity pedaling after a race to clear out excess lactate.
The best way I have heard the knowing you are in Z2 talking test phrased - if you were talking to someone on the other end of a phone call you can sustain the conversation indefinitely but the other person can tell you are exercising i.e. the effort is evident in your voice, micro pauses etc. A number of scientific sources state this invariably matches up very well with precise lab testing that most of us will never have the resources to undergo. The great thing is we can all talk out loud to ourselves when on a ride in or outdoors to get a feel for where this sits for us.
I inadvertently did a big chunk of zone 2 work by doing a cycle tour over 7 weeks across europe. I came back home and 3 weeks later did a standard distance triathlon after what I thought was no training and set a 15 minute pb for the cycle. In fact I did a 13 min pb for the whole event so the daily low intensity cycling was a huge fitness benefit to me.
As a keen Z3 cyclist and cancer survivor (I had half my right lung removed last year), this video was right on point, thanks! Great questions from Simon and very clearly answered by Iñigo! I am certainly guilty of training way too hard, way too long and then being so tired that I wouldn't be able to do the really high intensity training at the top end. Whilst I knew this was an issue, it is hard when you're riding with a group that likes to push hard! I have found the solution though, as I have also now have Atrial Fibrillation so have been forced to reduce intensity and duration of my riding. This may well be as a result of too much training and riding generally in Zone 3/4, so don't make my mistake and listen to Iñigo everyone!
I was a keen long distance runner with many marathons under my belt. Also, big into the high intensity stuff back then. I also developed A Fib and had to have an ablation which worked great TG. This appears to be a common enough condition among endurance athletes but you need to look after your heart and not push too hard continuously. Doing a lot more cycling these days and sticking to Zone 2.
The importance of LISS training is quite common knowledge in the distance running community but the general public doesn’t seem to know much about it, I appreciate you sharing this knowledge to more people with the huge platform you got.
During the early 90's, I lived in Norther California and was very serious about my training. My coach at the time (Early stages of Wenzel Coaching) preached this z1-z2 focused philosophy and honestly, it produced the best results for me. I had the privileged of keeping company of many elite/pro riders and what they use to tell me about riding w/ non-elite/pros was they rode too fast. I obviously couldn't keep up w/ them on the intensity days, but they would *chose* to invite me along for their z1/z2 days, if I promised not to go too fast (not that hard). This led to many, many enjoyable miles of chatting w/ the worlds best cyclist as we leisurely made our way from coffee shop to coffee shop for most of each day.
It’s really great to hear a professional voicing what I’ve been saying for years. Trouble is people ain’t patient enough. There is no quick fix, just Frequency, Functional and Fun. Best video I’ve seen in a while 👏🏻 ❤. Well done GCN.
Nice interview Si, well worth listening to... I'm in my early mid 70s and developed COPD (now stage 2 never having actively smoked) when I was aged around 67 largely through heavy road pollution and having biked as an endurance cylist for over 30 years too often in heavy traffic (both in the UK as a young teen and the EU Alps from age 40 onward), but also in NZ from 1980, a surprisingly heavily traffic polluted country emission wise especially in the biggest city Auckland with commuter traffic (in older vehicles of the larger Austrialian-US sort made in the 60s but driven in NZ in the 1970s, 80s and 90s). I'm still cycling. It's saved me absolutely no doubt at all. Kept the lungs open way more than I could have expected for the past 7 years. Never ever give up. Ever! Cycling is the best!
I can relate so much to this Zone 2 training. I`ve come back from having a brain tumor removed in 2020, i wanted to challenge myself to complete the Fred Whitton Challenge this year. I started a structured training (Spoked) last December and i thought the plan was far to easy after a couple of months mostly Z2. But it built a great base and by May i completed the Fred in 8hrs 34mins but i felt fresh at the end not burnt out. Then in October i went to Majorca for the first time in 3 years and smashed PB`s that i`d set 7 years ago. Zone 2 really does work. Great video.
That's the spirit dude, Z2 needs more love across the board, its broadly beneficial for so many things outside of riding 🤙🏾 congratulations on smashing those PBs 👌🏾
Awesome. This is definitely one of the most directly applicable videos for us mortal cyclists that I've seen on GCN. Very much appreciated and very well presented by Si. Thank you.
That was really interesting. Like the thought of either training the slow twitch system or fast twitch. It's made me realise that a lot of the time I don't keep the 2 separate. Quite often I sprint over a rise and he's made me realise that may be making the training less effective.
I was trying it out on the indoor trainer today. Doing 100 minutes. It is extremely hard to stay in zone 2. Also, I have a hard time feeling "satisfied" afterwards. It's a mental thing, but I need to feel exhausted to mentally feel like it was a good session. But I'm not giving up. Dr Iñigo definitely knows what he's talking about. So much knowledge. Thanks for uploading the full interview.
Thank you, Simon. I really enjoyed watching and learning from Inigo, and I really appreciate listening to full, articulate and intelligent responses, of which most mainstream news media outlets would only be interested in producing and releasing soundbites. It heartens me to know that GCN respect their audience and their intelligence. Great work, and really great interviewing!
He's talking about Polarized training. I've been doing Polarized training for years, so 80% - 90% of my riding is in zone 1 (polarized training uses only 3 zones) with 1 or 2 days a week used for super hard intervals. Zone 2 (tempo pace or "sweet spot") is really never used. And thus the problem riding with others. Every group ride out there is typically riding at sweet spot, hard but not hard enough, and too hard for zone 1. And if you try to find a local riding buddy, it's nearly impossible because most cyclists believe what SI believed which is you have to hammer it every time you're on the bike. So, most of my rides are solo, which is fine with me. Also, even if you find someone who agrees with the philosophy of polarized training, the odds that their zone 1 and your zone 1 are the same are pretty long.
I can guarantee you, pros used zone 2 in their training. Inigo just doesn’t say anything because SI does not ask the right questions. If you have pro hours to ride then follow that as black and white. Im sure an average weekend warrior only have 5 hours to train would not do just polarised training. It will always depends on the phases of training.
@@Jarek. Many. My ability to put in long miles without wearing myself out. I'm definitely faster and stronger than I was when I was doing like most others and just riding as fast as I could all the time. Plus there are other benefits. I actually enjoy riding when I do my zone 1 rides. I'm not going slow by any means, but I'm riding at a pace that actually allows me to enjoy the scenery, or talk with others I'm riding with. And there is much less burnout when the majority of your rides are endurance pace. So many cyclists I know end up taking time off the bike once or twice a year because they just get burned out from all the hammer fests. Cycling should always be enjoyable so you stay motivated to get on your bike. The minute it seems like work instead of fun, you're going to make excuses not to ride. Try it and see for yourself. 65-75% of your FTP is zone 1 in polarized training. Try riding at that pace for two hours and let me know how your legs feel. You'll be surprised at how much you'll feel it. Also, make sure you don't have any uncoupling. That means your heart rate should stay pretty much in the same range while riding at that zone. If it drifts up quite a bit, it's a sign that your fitness needs work. If after 30 minutes your heart rate is 125, and then after an hour it's 140, and after 90 minutes it's 145 or higher, that's not good. It should rise, but only a little. Let me know if you try it.
Keep in mind that Dr San Millán's five zones are based on bioenergetics and how muscles utilise different energy systems at different intensities of exercise, so his reference to zone 2 may not be directly comparable to your reference of zone 2, but I understand you're making a general point 🙂
@@james5150 That's very true. In a 5 zone system, which is most often used, my zone 1 would be their zone 2, my zone 2 would be their zone 3-4, and my zone 3 would be their zone 5. Either way, it is generally understood that you get the most benefit from either endurance effort or high intensity intervals. Most people trod along somewhere in the middle, which is the least helpful zone to ride in.
After some health issues I'm now back on the bike. I didn't realize how much I missed it. This video was very informative. I'm 71 and now getting back on the saddle. There's definitely fire left in the furnace!!
I watched some of his RUclips videos about 12 months ago and it was a lightbulb moment for me and have been using z2 indoors ever since and getting my high intensity outdoors only. I'm not a competition or club rider, just recreational, but it has definitely made me a stronger rider and helped me to lose weight at the same time. It feels counter-intuitve at first, but you soon feel the benefits. For us mere mortals there are some z2 calculators out there, but use with a pinch of salt - the being able to talk while riding is a good indicator. Also be aware there are different z2's, some are part of a 5 zone and some part of a 7 zone intensity level set up.
@thejonesy66 Interestingly, I pretty much do the reverse. I prefer to do my zone 2 work out on the road with longer, steady rides and my VO2 max intervals on the trainer. There's too many variables out on the road to control the intervals properly I find unless you just do hill repeats.
@@ashleyhouse9690 Correct, it is better to do your high intensity workouts on a trainer which are shorter compared to zone 2 long rides and gives you the facility to maintain the desired power under a control environment.
Interesting, I'm recovering from a collar bone fracture so only indoors for now but normally I do almost only high intensity on the trainer... how long shoud be this Z2 sessions indoor?
As a mountain biker I am interested in this topic too. I wanted to get more serious with training the right way but enjoy cycling outdoors so much, I can never stick to Zone 2 and keep pushing because I enjoy exhausting myself so much. Same with skiing, as ex racer I can only enjoy max angle full send. Maybe I need to do the opposite approach aswell.
Most effective advice I've ever been given on becoming strong on the bike, is to ride easier on easy days and harder on hard days. This video exactly explains why that works so well. Thanks GCN!
Amazing interview and such valuable information! Thanks GCN for arranging this and giving us basically the whole conversation, super interesting stuff! Also, Si knows how to talk to a scientist! As one myself, that kind of interest in the whole field (not only the bike specific things) strikes a sting in my heart too!
Awesome timing cause I pushed too hard this week while being sick and took a day off to ride even more, but I feel so tired today I don't wanna go out 😅 watching gcn and bike videos is a good alternative 🎉
This is outstanding and because I spend a lot of time in zone 3, it explains why so much of my training seems wasted. Also, my partner doesn't ride as much as me and worries that I'm not getting a workout when I ride with her. I can use her this to show that riding with her slower benefits my training to ride.
Great and very interesting video. keep up the good work. I have been pushing too hard every time I jump on the back and, instead of making me stronger, I have peaked and now I'm getting weaker. I'm definitely going to be doing more zone 2.
A few years ago I experienced this. I simply rode my normal courses at an easy pace well within my limits and after a few months was setting PBs on the local climbs. I write this as I'm about to go for a 2-hour spin.
Been there, done that! This makes sense. Z2 to get the body being efficient at using/clearing lactate and Z4+ for getting fast which produces lactate. Both systems need to be working well to get the best out of oneself. Scary how high pro's Z2 power tops out at though. Often above 290W's. Just crazy!
A great educational interview, and very interesting to hear how one field of study could potentially benefit athletes of all levels, our general health and well-being, as well as cancer treatment too. Thank you to GCN and Dr Iñigo San Millán for creating this video.
another great GCN info cast. Totally agree that this 'polarised' system of training is the way to go, as Tony Gibb said 'Know how to take easy days really easy so I could do hard days really hard. If you don’t do that you end up training at 90% all the time. Never hard enough to make a big difference and never easy enough to fully recover.' By the way - a pleasure to meet you in Cafe Nero in Ross Simon.
Understanding that video is about a year ago. New sub. This is exactly why fixed gear is good for training. You have control of the speed you are going even though it's constant pedaling. What this man is talking about is a similar way to work out, learn instruments, and practice breathing. It's slow burn, you let your body improve. Your body is producing more of what is needed to grow. If you move faster, you are just using the energy you have to feel tired at the end. If you move faster when lifting, you are burning the energy you have to be tired at the end. Train at a slower pace and your body will get used to that pace and will allow you to increase that pace. When I was learning piano my instructor taught me to learn each section of the song slowly. When I can do sections of the song without thinking about it, the body is used to it and that will allow me to increase the speed.
I’m 13 years old and learned about zone 2. I train 3 days in zone 2 and 1 day in all out training. I’ve been riding my road bike for 7 months now. I remember that early on, I couldn’t even finish the race. Now, I’m CAT 4 and competing agains older men.
I’d agree with what Si was saying at the end, that the Z2 described in the interview is probably slightly harder than I would have thought if you use the conversation measure as a guide. If I was asked I’d have said a full conversation is possible in Z2 so perhaps I can go a little harder and still be doing a valid Z2 ride
Another useful indicator of Zone 2 is the highest intensity of exercise at which you can still breathe through your nose. As soon as you need to breathe through your mouth, you're pushing a little too hard. 🙂
best interview on GCN hands down. What a great guy. Utterly fascinating. I started supporting Pogacar's charity after he mentioned it and started reading up on the metabolism thing re cancer. So interesting and hopeful. Having got into cycling as a way to get/keep fit and stay sane when I had cancer a few years ago no two topics could be closer to my heart. I wish them all the best with the research and hope so so much that this is the answer or start of one that we need so badly. (also going to do a quick reassessment of whether my zone 2 is actually zone 2...)
That was one of the best explanation I've heard on base training. You always hear that base is important, but explained that way will surely help me. I do push almost in all of my bike ride, and I do suffer from time to time of really debilitating leg cramps. I think now I do understand what may be the issue, and I'll surely refrain myself on pushing that hard in every rides so that I do build my "base". Thanks again GCN for that incredible interview !
@@gcn Fantastic video. Inigo was very insightful and informative. Interesting parallels with 'body building' training processes - I.e. working energy systems and using steady state cardio (Z2) / deload weeks to clear lactate after periods of high intensity training.
Thank you for doing this!!! I Have been doing 3-5 hours of zone 2 for the past year because of Inigo San Milan. I also have been doing GCN workouts for almost 4 years. Love this!
So glad to see Iñigo over here. I've been doing only fasted training for over a decade. It shaped everything I do and I can't imagine doing otherwise. I'm always trying to convince clients that part of their belly and their energy problems are one and the same but it's so hard to break people from the "fuel your workout with products" mentality.
I think this was my favorite video you've done to date. Not only did it have a wealth of easy-to-understand information for all levels of riders, I found Dr. San Millan a joy to listen to. He explained things so well! I'd love to see more content like this on the channel. Well done.
Great video! Have been quite a few videos on training advice recently. Why not pull it all together with a video or two on training plan design, that brings together all the insight from this video, the strength training video and your combined experience? I think it would help a lot of people, including me!
It's the trickle down info that helps us improve our lives that makes cycling so cool. Especially info that improves this vehicle we use to cruise through life, our bodies. Thanks for the lesson, very nice. Keep it fun folks!
I'm not a biker but I've run some trail marathons and the zone 2 work was such a nice, sustainable way to train. Over time you get faster and faster at that lower heart rate and it's amazing how far you can travel in 4-5 hours when you dial that in.
Oh boy I can't even imagine training any different at this point. Especially for running it's so much higher impact. A good 10+ miler steady state effort is just a dream. My favorite workouts during the week for sure :)
Really please you posted this up , definitely feeling wipe out with intense rides and now I know a super way with all the advice to get back in the game ❤🚴♂️
Great topic! Doing Z2 training for over two years, absolutely love it. My experience - first you need patience, because you ride / run slowly and it takes time to get better. Second, you need to get the zones right - preferably by blood testing during excersise. Third, combine with interval training. And get yourself a qualified coach for that. @gcn keep doing this type of content
This video inspired me to have a go! Takes a load of concentration and self control to sit at z2 for over an hour! Let’s hope it works! Truly cycling inspiration thank you
Great video GCN. Ignacio is the man! For anyone who enjoyed this, I'd highly recommend listening to Peter Attia's podcast with Ignacio. There are actually two. It offers a really big deep dive into all this stuff if you're interested in the complex molecular details.
Love hearing from professionals in specific fields as they relate to cycling. Thank you GCN for being the conduit, channeling us this information. Great interview. Si, Christchurch, NZ.
Great content. I have been following Iñigo and his Zone 2 training for about 3 years now. Just awesome. So you have some idea, my Zone 2 HR is between 75-81% of my max HR and 200w. Blood lactate averages about 1.7 at this level. Sleep or quality of sleep can affect these numbers as well. Weekend worrier, former racer
@@uberpekes Percentage of HR isn't a realiable indicator of Zone 2 because other confounding variables influence heart rate (e.g. level of fitness, how fatigued you are, how well you slept, whether you've eaten recently, etc.). The talk test is more reliable. Another great test is aiming for the highest intensity of exercise at which you can still breathe through your nose (assuming you don't have any difficulties breathing through your nose normally). 🙂
Very interesting interview! What I would like you to explore more is how to actually do zone 2 training efficiently. If you ride in a bunch or just with a few mates, you are either in the wind or on the wheel, so it's not easy to keep that pure zone 2 all the time. Same if you are in an area with mountains, it can be hard to keep in zone 2 going up and actually hard to get over zone 1 on the descent.
I can’t do Z2 with anyone else. Too anti-social! Indoors is good. Inigo SM suggests a minimum of 3 sessions of 90 mins a week will result in improvements. I now do these on the Atom Wattbike and clamp my HR with ero mode (power) so I get the full 90 mimutes every time, no fluctuations like I would outside.
Well that was a real eye opener. A scientist with a yellow jersey behind him telling you to go slow, I'm taking that advice and running with it. Well maybe I'll just walk at a fast pace with it! Thanks for the great information GCN.
Great interview and very interesting. I have heard of intermittent fasting but would like to know more about the fasting referred to in the interview and how it works for cycling. Excellent videos as always. Keep it up.🎉
What an awesome topic and interview! I have a horrible time riding in Zone 2. Im encouraged by the head of the racing team I’m on to put in more time at zone 2, and I just slough it off and hit another HIT session. I’m 66 now but in my youth I was an international level track and field sprinter - 100m, 200m and 400m. I had the personal moto ‘if I can’t go fast I don’t go’. I hated long slow runs then, still do. My brain says I’m a greyhound, but my heart now says no you’re not. This interview has given me a new perspective on zone 2 riding and much to think about. Thank you Simon and GCN for doing this program.
This is absolutely fascinating! Thank you for this. I have MELAS, which is a mitochondrial mutation that means I don't produce energy properly. I have to ride exclusively in zone 2, but it really helps
Just great to be reminded that zone2 really does work. And endless HIT schedules end in tears always! And heart rate training is not obsolete. All the measures are good to utilise when they work best. Thanks very much!
Great interview! Interesting stuff. I've seen huge improvement this last year in overall fitness by doing a lot of zone two during the week... with a bit of intervals or hill climbs added in... but mostly zone two improving my baseline.
I found moving to a lot of z2 made a lot of difference when I used to run; people would wonder why I was joining a slower group, but come race day it showed its value. I found it worked less well with cycling, because my musculature (or lack thereof) meant I could reach a point where I couldn't push the pedals despite my HR still being very low. I'd be interested in thoughts on how the muscular requirements of cycling compared to running may change things.
The talking thing, either being able to talk or not while pedaling along, was a good point. I will chat while riding in a group...........and some people can hardly say a word. I dont realize how hard they're working even to stay in the draft. They will finish the ride and say it was the hardest ever. It takes miles and miles to make it work. I never took the time to do this when I was younger.
Very interesting interview! Thanks for that! One thing that really struck me was when he says that if you break the zone 2 “mode” by going too fast for a short while, it may take up to 30min to get back in the right mode… I’ve been feeling that exact scenario many times in my training without being able to explain it. If I let my guard down for a while and let myself slip into a faster pace, after going back to a slower pace again, it doesn’t feel the same anymore. As if my body is activated in another level and where my heart rate becomes much more responsive and sensitive to hills/or other change of pace. Hard to explain. Anyway… cool stuff and thanks for bringing us this good interview!
I've definitley improved by doing more zone 2 work, my only problem is self discipline - I go out for a steady ride and always end up thrashing it half way through. ;0)
Zone 2 riding still requires progressive stress and rest. The single important variable is TIME. So you need to progressively step up your weekly Z2 time in a stair-stepped pattern for, say three weeks, then take a down week for rest. But you need to keep increasing Z2 to get increased benefits. But with Z4, it’s complex but more related to intensity levels and repeatability. But just doing the same Z2 every week is not optimal. Increase your time progressively to build base fitness and take rest weeks regularly. I typically advise people to do Z2 alone as it avoids competitive situations where intensities get too high. And flatter courses are generally better as they avoid high intensities climbing and zero descending. Just my two cents.
@@aethylwulfeiii6502 Thanks. I wrote the first periodized training programs for the US national team back in the early 1990s. Heart rate-based as we didn’t have power meters yet. I learned about how to periodize endurance programs from weight training and Scandinavian cross-country (Nordic) ski coaches. Nobody had systematically periodized cycling training yet or integrated weight training with cycling in-season. If anyone was weight training, they did it in the winter and promptly lost any gained strength in the spring when they stopped. I was the first to use computer spreadsheet programs like Excel to create customizable periodized programs that I could adapt to any individual or race schedule. I even created double periodized programs for one of my masters athletes who was a world-class age-group cyclist and Nordic skier and she needed a custom approach.
Just a reminder that your Z2 will change quickly if your are new to cycling. I started with a 226w ftp exactly one year ago and now i do my easy endurance at 200w (105-110bpm). Buying an indoor trainer is what really changed everything for me!
Really interesting video. Would love to see something on how to plan outdoor rides to target different training goals (not all of us have space for an indoor trainer at home!). Living in Devon I have a lot of huge hills all around and struggle to plan something that doesn't push me into zone 4 within the first 30 minutes
Just slow down. I also live in SoCal, and while I am pretty far above average for power, you don't have to use it all the time. Put it in the lowest gear you have and enjoy the view!
Interesting, I used to do a lot of running before I got into cycling and the "barely able to hold a conversation" has been the target point for run pacing for training for as long as I'd been keeping up with my fitness. Seems like it's a pretty good "universal" rule for most cardio based sports.
An equivalent target is the highest intensity of exercise at which you can still breathe through your nose (assuming you don't have any difficulties breathing through your nose normally). Again, another target point used by runners for decades 🙂
I like your video. I watched the two hour podcast with Dr San Millan and Dr Peter Attia. It was great insight. I would suggest you watch it, as the "ZONE 2" they are discussing is not what cyclists call zone 2. I've now been doing this middle cycling "ZONE 3" , NOT SWEET SPOT AND NOT ZONE 2, for almost a year now and it works very effectively. How I interpreted it was you need to stay between 70-80% of your maxHR while not using above threshold power. Complicated for rolling hill style outdoor rides. It means throttling back to your easiest gear on some climbs, and even dropping the cadance to stay on just below your sweet spot on the climbs, but then actually riding harder than you usually would on the descents to stay inside the magic 70-80% maxHR, or what they call Peak Fat burning zone. All my solo rides are now done like this and sometimes I add in the threshold for the last 10-20 mins to get the benefit of the high intensity. I do 100-250 miles a week over 4 days. I use to get dropped by the ex-racers and triathletes on the Saturday group ride, but not anymore. Average speed in the group ride is never below 21mph, sometimes the middle hour is 25mph.
Really loved this kind of content from you guys . Getting into the medical with at home tips from a phd to help diagnose your zones in training. And the detail . Loved it great questions. Maybe he would be down for some follow up questions from viewers presented and sorted through by gcn
What did you make of this interview with Iñigo?
Absolutely fascinating, definitely gonna start implementing some zone 2 into a few rides a week!
Interview was great! Hardest part is being disciplined to do Z2. Fighting the ego when a rider passes you. I went from doing 19 km/h at Z2 to 30km/h at the same Z2 heart rate in 4 months. Takes practice.
GCN training needs to come out with some scenic 90minute Z2 rides that we can follow on the turbo. Record the presenters doing a Z2 easy ride from the bike and release it once a week. With them talking and make it fun. Similar to this by SAFA Brian ruclips.net/video/nbsWYYtOcFk/видео.html
This information has no relevance to me; I don't train, I just ride my bike in the park. But it sounds terribly complicated. And it brings back memories of other doctors coaching other cyclists, frankly.
Realizing I've been in zone 1 all the time 😅
I used a 90% Z2 training plan for ultramarathon running and it absolutely works. My aerobic endurance has never been better. When I picked up cycling, I carried over this type of training and it has worked out really well on the bike too.
I have stage four cancer and was told that I had 4-6 months.. 10 years ago now. I am a very old roadie and extremely interested in this type of interviews/ research.
I honestly believe that my bike has kept me alive.
Great interview
Big words here. Keep it up!
It is known that cancer cells need high amounts of glucose in order to lie and grow and once you restrict glucose, they may stop growing, so yes, practicing endurance sport helps the body eliminate the excess of glucose due to today's high carb diets.
**live not lie
so happy you're still with us
@@AR-lz2br It's not as simple as you state. Healthy cells also require glucose and there's no way of telling our bodies to let healthy cells have the glucose they need, but not give it to the cancer cells.
Having this level of information for free is just incredible. Thanks GCN!
Then Peter Attia's interviews with Dr San Millán will BLOW YOUR MIND! 😊
@@james5150 I'll be sure to check those. I'm just now diving into these subjects because I don't want to make in cycling the same mistake I did in running: too hard too often. Cheers.
Absolutely 👍👍👍
I worked under Dr. San Millan for 5 years in his Colorado lab and also hung on to every word he said. He is brilliant, making a huge impact with his research and great at breaking down and explaining complex physiological concepts!
Truly a legend!
If possible, you can dedicate your precious time and knowledge to advise amateur cyclings.
Thanks
I’m working on this. I rarely ride over 10 hrs/week. A lot of 6-7 hr weeks but I’m going to put as much as I can into training like this.
@@johnpenner1318 the way i think about it isn't necessarily"get faster" but avoid burnout and injury. Maybe that's just because I'm old though 😜
Phil Maffetone approach. Mark Allen was his pupil. Formule 180-age = zone 2 with adjustments.
This really explains why when I was commuting by bike I was always so much stronger/faster than when only training via turbo with occasional outdoors. Zone 2 always seemed to be the right intensity for the commute. Of course, I was also 10 years younger at the time...
Yesss exactly that. I was so slim in Japan, cycling to work in a shirt, and this only going zone two.. But regularly, and I think having to work, rather than sitting in the sofa, also maintained my metabolism
Oh. Very good point. Especially given xovid and lack of commuting.
Perhaps riding your bike twice a day contributed as well:p
especially riding in traffic. the constant braking, slowing down, ramping up again, full stops then oops forgot to switch to the lower chainring then the traffic resumes, it all adds to the training. the bumps on the road? additional plates to your bar in gym terms.
And it really explains why when I was commuting by bike I always was tired and often getting cold. Been riding in Zone 3/4 all the freakin time, seemed right back then;)
As a reminder. Your Zone 2 will change as you gain endurance, so don't think your giving up fitness. Be positive about your outcome from a 3 day focus in Z2. You will see results!
Keep it up GCN, we need these interviews.
Great point. As Iñigo says, Tadej Pogačar's zone 2 is serious power output!
Already seen a huge difference after my first 4 days!
I've been following this training regime for 7 months. Yes my zones have changed positively, but whilst I have been using the 80/20 idea, I've lost 11 watts of power and my strength has decreased terribly. Personally I think as individuals we should be looking at "what fits me best". Sorry to put a damper on the discussion.
@@47Seagull then your nutrition or recovery might be off. How on top of your nutrition are you? Are you taking supplements like magnesium, Omega 3, zinc, vitamins, etc? Enough protein and carbs? Do you fuel during your workouts? Do you stretch daily? Sleeping enough? Honestly all these points unlocked crazy fitness for me in terms of endurance and strength training. Injury free too so far. One thing I did notice with higher volume / lower intensity training is you gotta fuel up before, during and after your sessions.
this might be a weird question but how do you measure when your zones have changed? how do you determine that or what is even meant by that? I come from running so not completely uaware of the concept but just don‘t get that
I have to be honest and say that I haven’t been a fan on GCN content for a while but this interview of absolute gold. Well done Simon on great questions, style and a really good summary at the end. One of the best videos I’ve seen on RUclips. 👏🏻
Haterz gonna hate 😉
@@ironmantooltime haters? "Reviewing" sponsored gear with conflict of interest claims is being a hater? Dipsh*t
@@quantumdecoherence1289 sorry darling, looks like you were deleted 😘
@@ironmantooltime criticism = hate nowadays. Snowflake generation.
agree, simon is a great interviewer.
As a novice rider that enjoys cycling SOOO much as it is the catalyst for my weight loss and maintenance for the last three years, I appreciate your sharing this VALUABLE information and presented in a way that my novice brain can put it to use. A+++
Thanks Craig! The brilliant thing is, is that we can all incorporate this into our riding, and see improvements!
I suck, but I'm healthy and feel pretty darned good. I once read elite level athletes only hit it hard once a week, the rest is training like this guy says. Best gains in lifting are ay 70% of one rep max effort. Mike Metzler worked some good suff on not overtraining in bodybuilding back in the 70s-80s
Time crunched, pushing 50 weekend warrior here. This was the single best GCN video I've ever seen. Zone 2 is a critical oversight in everything I've ever done and just from hearing this I believe this will have the single biggest impact on my training. Thank you!
Its worked for me. Ive ended up doing 3 local group rides per week, and at about zone 2 for 2 hours or so per ride..........and I kept thinking this cant be doing much for me.
But its fun and I kept doing the rides. For well over a year and a half.
Coming back from getting a new knee put in, and some years off due to the knee.
I wasnt showing much improvement on the occasional climbing ride.............but then something happened, and my pace now keeps picking up, and up. I'm going better overall than I was 30 years ago. I'm 65 and I keep ending up at the front on climbs ,some riders in their 40's and they are busting a gut trying to beat me. Obviously we arent racers.
But I'm always competitive no matter what, I'm enjoying be able to just pick up and go on climbs, and cruise at a good pace on flat. 22mph is fine for a long time. Its all about the fun.
How’d it go?
Iñigo's words absolutely match with my personal experience. I was freaking out about getting faster and doing all that high intensity trainnings, but got into a plateau. Then I saw some other guys in the internet saying you could improve your performance by taking it easier. I tryed it. Guess what? It worked. So now I always do some Z2 trainings.
This is the only thing I miss about my daily commute and not doing it anymore. 5 days 1hr per day Z2 just to get to work. It was a great free workout, the fitness level was so high with this as a base.
I absolutely loved this ❤! Please make more of theses sports performance and science based videos.
Thanks Adam
I encourage you to listen to Peter Attia's excellent interviews with Dr San Millán if you interested to dig deeper 🙂
@@james5150 Attia, Endurance Planet, Andrew Huberman, and of course Dylan Johnson (especially for despite backwards cap Dylan take on things) are my go-to podcasts for related information. I missed the one you mentioned so that going up on my playlist today! 🙏🏻 thanks.
Definitely, we all know cycling and exercise are healthy for you but when you learn more about how healthy and how to make the most of your time it makes all this exercise even more motivating 🙏💪👍
Having done my fair share of overtraining, I appreciate what this guy is saying. There is nothing worse than putting more energy into training and seeing results get worse. Not to mention the night sweats and low quality sleep that comes with overtraining.
What's interesting about what he's advocating is how similar it is to the way it was suggested that riders should train in the 80's.
I did zone 2 last offseason to condition for mountain biking because I was recovering from shoulder surgery. My second ride of the season resulted in a PR. Basically I was conditioned equally to the end of the season.
This is the way I train. I ride a 'Slow, Steady distance' from home to my son's home 90 miles away. A small amount of soreness but no D.O.M.S.
I share out grinding ( uphill ) and spinning. BTW, longest gear on my touring bike is 75 inches, and when it's loaded, its 32 lb.
I manage my intake and rest at cafes along the route. Essential to stretch out before getting going.
PS. I'm 62.
90 milers at 62, I'll be aiming for that in 30 years time, legend
Make sure you stretch at the end also. Keep enjoying the 🚴
Awesome! SSD was always a staple of base training for years.
@@acanfield87 Well, they also called it "LSD," "long slow distance," back in the '70s, something like the first 1000 miles after the winter layoff to burn off the fat and get everything working.
Yes! I’ve been taking ‘LSD’ since I first started riding in the 80’s 😮! I think I’ve been practicing/benefiting from Zone 2 training for years and not aware of it. I’m 68 now 😂
In rowing this is talked about as base speed training. It's been well recognized in the community that base speed training is essential to get faster. Glad to see this is actually supported.
Weirdly enough I find it difficult to reach Zone 2 when rowing (unless I push hard), which seems counterintuitve given rowing engages more muscles than cycling. 😊
It used to be the basis for many UK club rides in the past, youngsters were advised "little ring until Spring" and "Winter miles mean Summer smiles" but it became unpopular because it requires patience and consistency - riders with egos thought that winning town sign sprints in January was important.
When HIIT training and Zwift soared in popularity these longer rides were maligned unfairly as 'junk miles' but we now know that the polarised method is still valid for recreational and amateur cyclists as well as professionals.
I've been doing this for a while now and find zone 2 type riding is more fun and I can enjoy the ride and my surroundings much better if I'm not so focussed on making every ride a hard one in an attempt to get fitter.
I've made some progress in the last two months by putting most of my time in the saddle in zone 2. I notice the improvement on sprints over short hills. Feels good to blast over my favorite bumps faster with less thigh burn. This video confirms what I'd suspected. BTW, I'm 66.
Good on ya, I'm 65 and giving it bloody hell. Ive never been better than mid to back of pack on climbs.
Now I'm going better than when I was 30. (I wasnt fast then) It really surprises me, I seem to go better every ride out.
Almost 2 years of around zone 2 group rides seems to have worked..it takes much time to make it happen. For me anyway.
Do you refer to zone 2 effort or zone 2 heart rate?
Fascinating to draw the link with metabolism and cancer treatment as well as his statements about how nothing has changed and we need to push into new lines of thought. So I can tell my non cyclist friends who shake their head at me when I get excited about a race that pro cycling is contributing to cancer research. Thank you Dr. San Millan. Go CU!
Yes been doing alot of reading lately on how to reverse types diabetes , best diet etc . Fasting has come up alot . There is a lot of hype around, even with Dr making false claims on utube . I watch nutrition made simple lots of science information on healthy diet. But yes there is evidence on how fasting can slow some cancers and speed up other cancers . But no doubt an active life style , healthy bmi bodyweight low calorie intake and healthy foods can make a real difference on cancer and diabetes
Fantastic information. As a cancer patient, I found the section on the causes of cancer particularly informative. I also liked the information on Zone 2 training. That is something I will do once I am back on my bike. Dr. San Millian is a brilliant, multi-talented man.
Wishing you the best with your illness, Jeff. Look forward to you being out on the bike in due time 👍
@@murphyia1980 Thank you. I appreciate your good wishes.
Thank you for making this video! I too have fallen into the trap of doing intense training sessions all the time thinking it will help me improve
It can be really hard to take a step back as it feels we're not improving when actually we are!
Thank you for you making how to ride bike.
Was planning on making this winter predominantly Z2 after overtraining the last two winters. Glad I saw this as it was getting tempting to just go hard as that's so ingrained.
Lol you know you're still going to overtrain 😂
@@ironmantooltime 😆 yup, probably...
That was one of the best videos you guys have done love it when you talk to experts and get more into the science behind health and fitness on the bike
Great interview! I had already listened to Iñigo in the Peter Attia podcast, and I highly recommend checking those out if anyone is interested in the details, but this one goes straight to the main points of Z2 training. Iñigo is also the guy who introduced low intensity pedaling after a race to clear out excess lactate.
Speaking in sentences: Zone 1
in phrases: Zone 2
in words: Zone 3
Grunts: Zone 4
The best way I have heard the knowing you are in Z2 talking test phrased - if you were talking to someone on the other end of a phone call you can sustain the conversation indefinitely but the other person can tell you are exercising i.e. the effort is evident in your voice, micro pauses etc. A number of scientific sources state this invariably matches up very well with precise lab testing that most of us will never have the resources to undergo. The great thing is we can all talk out loud to ourselves when on a ride in or outdoors to get a feel for where this sits for us.
I inadvertently did a big chunk of zone 2 work by doing a cycle tour over 7 weeks across europe. I came back home and 3 weeks later did a standard distance triathlon after what I thought was no training and set a 15 minute pb for the cycle. In fact I did a 13 min pb for the whole event so the daily low intensity cycling was a huge fitness benefit to me.
those cycle tourists are fitter than they let on! 👀 Well done on the PB 🙌
A new cyclist here! Bought a bike following the UCI road world championships coming to town and I'm obsessed. Thanks for another great video
As a keen Z3 cyclist and cancer survivor (I had half my right lung removed last year), this video was right on point, thanks! Great questions from Simon and very clearly answered by Iñigo! I am certainly guilty of training way too hard, way too long and then being so tired that I wouldn't be able to do the really high intensity training at the top end. Whilst I knew this was an issue, it is hard when you're riding with a group that likes to push hard! I have found the solution though, as I have also now have Atrial Fibrillation so have been forced to reduce intensity and duration of my riding. This may well be as a result of too much training and riding generally in Zone 3/4, so don't make my mistake and listen to Iñigo everyone!
Bike! Now that sounds good! 🏎
I was a keen long distance runner with many marathons under my belt. Also, big into the high intensity stuff back then. I also developed A Fib and had to have an ablation which worked great TG. This appears to be a common enough condition among endurance athletes but you need to look after your heart and not push too hard continuously. Doing a lot more cycling these days and sticking to Zone 2.
Rest, too, is an important part of a training program and often overlooked/ignored.
As both a triathlete and a cancer survivor, I loved this interview! Thank you!
The importance of LISS training is quite common knowledge in the distance running community but the general public doesn’t seem to know much about it, I appreciate you sharing this knowledge to more people with the huge platform you got.
During the early 90's, I lived in Norther California and was very serious about my training. My coach at the time (Early stages of Wenzel Coaching) preached this z1-z2 focused philosophy and honestly, it produced the best results for me.
I had the privileged of keeping company of many elite/pro riders and what they use to tell me about riding w/ non-elite/pros was they rode too fast.
I obviously couldn't keep up w/ them on the intensity days, but they would *chose* to invite me along for their z1/z2 days, if I promised not to go too fast (not that hard). This led to many, many enjoyable miles of chatting w/ the worlds best cyclist as we leisurely made our way from coffee shop to coffee shop for most of each day.
It’s really great to hear a professional voicing what I’ve been saying for years. Trouble is people ain’t patient enough. There is no quick fix, just Frequency, Functional and Fun. Best video I’ve seen in a while 👏🏻 ❤. Well done GCN.
Lack of PATIENCE is the reason most people fail in life.
Nice interview Si, well worth listening to... I'm in my early mid 70s and developed COPD (now stage 2 never having actively smoked) when I was aged around 67 largely through heavy road pollution and having biked as an endurance cylist for over 30 years too often in heavy traffic (both in the UK as a young teen and the EU Alps from age 40 onward), but also in NZ from 1980, a surprisingly heavily traffic polluted country emission wise especially in the biggest city Auckland with commuter traffic (in older vehicles of the larger Austrialian-US sort made in the 60s but driven in NZ in the 1970s, 80s and 90s). I'm still cycling. It's saved me absolutely no doubt at all. Kept the lungs open way more than I could have expected for the past 7 years. Never ever give up. Ever! Cycling is the best!
slow is smooth, smooth is fast...a piece of advice that changed my entire training strategy
Wise approach for most things in life. 🚲
I can relate so much to this Zone 2 training. I`ve come back from having a brain tumor removed in 2020, i wanted to challenge myself to complete the Fred Whitton Challenge this year. I started a structured training (Spoked) last December and i thought the plan was far to easy after a couple of months mostly Z2. But it built a great base and by May i completed the Fred in 8hrs 34mins but i felt fresh at the end not burnt out. Then in October i went to Majorca for the first time in 3 years and smashed PB`s that i`d set 7 years ago. Zone 2 really does work. Great video.
That's the spirit dude, Z2 needs more love across the board, its broadly beneficial for so many things outside of riding 🤙🏾 congratulations on smashing those PBs 👌🏾
Awesome. This is definitely one of the most directly applicable videos for us mortal cyclists that I've seen on GCN. Very much appreciated and very well presented by Si. Thank you.
That was really interesting. Like the thought of either training the slow twitch system or fast twitch. It's made me realise that a lot of the time I don't keep the 2 separate. Quite often I sprint over a rise and he's made me realise that may be making the training less effective.
I was trying it out on the indoor trainer today. Doing 100 minutes. It is extremely hard to stay in zone 2. Also, I have a hard time feeling "satisfied" afterwards. It's a mental thing, but I need to feel exhausted to mentally feel like it was a good session. But I'm not giving up. Dr Iñigo definitely knows what he's talking about. So much knowledge. Thanks for uploading the full interview.
Cant you sprint at the end of your session?
Thank you, Simon. I really enjoyed watching and learning from Inigo, and I really appreciate listening to full, articulate and intelligent responses, of which most mainstream news media outlets would only be interested in producing and releasing soundbites. It heartens me to know that GCN respect their audience and their intelligence. Great work, and really great interviewing!
He's talking about Polarized training. I've been doing Polarized training for years, so 80% - 90% of my riding is in zone 1 (polarized training uses only 3 zones) with 1 or 2 days a week used for super hard intervals. Zone 2 (tempo pace or "sweet spot") is really never used. And thus the problem riding with others. Every group ride out there is typically riding at sweet spot, hard but not hard enough, and too hard for zone 1. And if you try to find a local riding buddy, it's nearly impossible because most cyclists believe what SI believed which is you have to hammer it every time you're on the bike. So, most of my rides are solo, which is fine with me. Also, even if you find someone who agrees with the philosophy of polarized training, the odds that their zone 1 and your zone 1 are the same are pretty long.
I can guarantee you, pros used zone 2 in their training. Inigo just doesn’t say anything because SI does not ask the right questions. If you have pro hours to ride then follow that as black and white. Im sure an average weekend warrior only have 5 hours to train would not do just polarised training. It will always depends on the phases of training.
Any tangible improvements from Polarized trainings? Cheers!
@@Jarek. Many. My ability to put in long miles without wearing myself out. I'm definitely faster and stronger than I was when I was doing like most others and just riding as fast as I could all the time. Plus there are other benefits. I actually enjoy riding when I do my zone 1 rides. I'm not going slow by any means, but I'm riding at a pace that actually allows me to enjoy the scenery, or talk with others I'm riding with. And there is much less burnout when the majority of your rides are endurance pace. So many cyclists I know end up taking time off the bike once or twice a year because they just get burned out from all the hammer fests. Cycling should always be enjoyable so you stay motivated to get on your bike. The minute it seems like work instead of fun, you're going to make excuses not to ride. Try it and see for yourself. 65-75% of your FTP is zone 1 in polarized training. Try riding at that pace for two hours and let me know how your legs feel. You'll be surprised at how much you'll feel it. Also, make sure you don't have any uncoupling. That means your heart rate should stay pretty much in the same range while riding at that zone. If it drifts up quite a bit, it's a sign that your fitness needs work. If after 30 minutes your heart rate is 125, and then after an hour it's 140, and after 90 minutes it's 145 or higher, that's not good. It should rise, but only a little. Let me know if you try it.
Keep in mind that Dr San Millán's five zones are based on bioenergetics and how muscles utilise different energy systems at different intensities of exercise, so his reference to zone 2 may not be directly comparable to your reference of zone 2, but I understand you're making a general point 🙂
@@james5150 That's very true. In a 5 zone system, which is most often used, my zone 1 would be their zone 2, my zone 2 would be their zone 3-4, and my zone 3 would be their zone 5. Either way, it is generally understood that you get the most benefit from either endurance effort or high intensity intervals. Most people trod along somewhere in the middle, which is the least helpful zone to ride in.
After some health issues I'm now back on the bike. I didn't realize how much I missed it. This video was very informative. I'm 71 and now getting back on the saddle. There's definitely fire left in the furnace!!
Amazing sir!
Great effort mate
I watched some of his RUclips videos about 12 months ago and it was a lightbulb moment for me and have been using z2 indoors ever since and getting my high intensity outdoors only. I'm not a competition or club rider, just recreational, but it has definitely made me a stronger rider and helped me to lose weight at the same time. It feels counter-intuitve at first, but you soon feel the benefits. For us mere mortals there are some z2 calculators out there, but use with a pinch of salt - the being able to talk while riding is a good indicator. Also be aware there are different z2's, some are part of a 5 zone and some part of a 7 zone intensity level set up.
@thejonesy66 Interestingly, I pretty much do the reverse. I prefer to do my zone 2 work out on the road with longer, steady rides and my VO2 max intervals on the trainer. There's too many variables out on the road to control the intervals properly I find unless you just do hill repeats.
@@ashleyhouse9690 Same here.
@@ashleyhouse9690 Correct, it is better to do your high intensity workouts on a trainer which are shorter compared to zone 2 long rides and gives you the facility to maintain the desired power under a control environment.
Interesting, I'm recovering from a collar bone fracture so only indoors for now but normally I do almost only high intensity on the trainer... how long shoud be this Z2 sessions indoor?
As a mountain biker I am interested in this topic too. I wanted to get more serious with training the right way but enjoy cycling outdoors so much, I can never stick to Zone 2 and keep pushing because I enjoy exhausting myself so much. Same with skiing, as ex racer I can only enjoy max angle full send. Maybe I need to do the opposite approach aswell.
Most effective advice I've ever been given on becoming strong on the bike, is to ride easier on easy days and harder on hard days. This video exactly explains why that works so well. Thanks GCN!
Absolutely! Thanks for watching Mark 😁
Amazing interview and such valuable information! Thanks GCN for arranging this and giving us basically the whole conversation, super interesting stuff! Also, Si knows how to talk to a scientist! As one myself, that kind of interest in the whole field (not only the bike specific things) strikes a sting in my heart too!
I love when someone is both brilliant and humble, such a rare combination 👍👍👍
Awesome timing cause I pushed too hard this week while being sick and took a day off to ride even more, but I feel so tired today I don't wanna go out 😅 watching gcn and bike videos is a good alternative 🎉
I skipped work to rest today from 3 days of riding. I'm doing exactly the same watching these videos. I'm calling it active recovery 😂
Amateurs. A professional knows you don’t try to win the work outs.
This is outstanding and because I spend a lot of time in zone 3, it explains why so much of my training seems wasted. Also, my partner doesn't ride as much as me and worries that I'm not getting a workout when I ride with her. I can use her this to show that riding with her slower benefits my training to ride.
Great and very interesting video. keep up the good work. I have been pushing too hard every time I jump on the back and, instead of making me stronger, I have peaked and now I'm getting weaker. I'm definitely going to be doing more zone 2.
A few years ago I experienced this. I simply rode my normal courses at an easy pace well within my limits and after a few months was setting PBs on the local climbs. I write this as I'm about to go for a 2-hour spin.
Been there, done that! This makes sense. Z2 to get the body being efficient at using/clearing lactate and Z4+ for getting fast which produces lactate. Both systems need to be working well to get the best out of oneself. Scary how high pro's Z2 power tops out at though. Often above 290W's. Just crazy!
That must be some heavy riders, no?
@@Rcck.7282 Not super heavy. Generally around 70/75kg
@@swites so 4W/kg for Z2,whoa
A great educational interview, and very interesting to hear how one field of study could potentially benefit athletes of all levels, our general health and well-being, as well as cancer treatment too. Thank you to GCN and Dr Iñigo San Millán for creating this video.
another great GCN info cast. Totally agree that this 'polarised' system of training is the way to go, as Tony Gibb said 'Know how to take easy days really easy so I could do hard days really hard. If you don’t do that you end up training at 90% all the time. Never hard enough to make a big difference and never easy enough to fully recover.' By the way - a pleasure to meet you in Cafe Nero in Ross Simon.
Understanding that video is about a year ago. New sub.
This is exactly why fixed gear is good for training. You have control of the speed you are going even though it's constant pedaling.
What this man is talking about is a similar way to work out, learn instruments, and practice breathing. It's slow burn, you let your body improve. Your body is producing more of what is needed to grow. If you move faster, you are just using the energy you have to feel tired at the end. If you move faster when lifting, you are burning the energy you have to be tired at the end.
Train at a slower pace and your body will get used to that pace and will allow you to increase that pace.
When I was learning piano my instructor taught me to learn each section of the song slowly. When I can do sections of the song without thinking about it, the body is used to it and that will allow me to increase the speed.
I’m 13 years old and learned about zone 2. I train 3 days in zone 2 and 1 day in all out training.
I’ve been riding my road bike for 7 months now. I remember that early on, I couldn’t even finish the race. Now, I’m CAT 4 and competing agains older men.
Awesome Xaven!
Great Stuff 👍
Dude, at the age of 13 you improve irrespective of what you actually do on your bike😂
I’d agree with what Si was saying at the end, that the Z2 described in the interview is probably slightly harder than I would have thought if you use the conversation measure as a guide. If I was asked I’d have said a full conversation is possible in Z2 so perhaps I can go a little harder and still be doing a valid Z2 ride
Another useful indicator of Zone 2 is the highest intensity of exercise at which you can still breathe through your nose. As soon as you need to breathe through your mouth, you're pushing a little too hard. 🙂
best interview on GCN hands down. What a great guy. Utterly fascinating. I started supporting Pogacar's charity after he mentioned it and started reading up on the metabolism thing re cancer. So interesting and hopeful. Having got into cycling as a way to get/keep fit and stay sane when I had cancer a few years ago no two topics could be closer to my heart. I wish them all the best with the research and hope so so much that this is the answer or start of one that we need so badly. (also going to do a quick reassessment of whether my zone 2 is actually zone 2...)
That was one of the best explanation I've heard on base training.
You always hear that base is important, but explained that way will surely help me.
I do push almost in all of my bike ride, and I do suffer from time to time of really debilitating leg cramps.
I think now I do understand what may be the issue, and I'll surely refrain myself on pushing that hard in every rides so that I do build my "base".
Thanks again GCN for that incredible interview !
16:54ish to 16:57ish - One of the Best Set of words ever:
"You can't understand perfection if you don't know what IMPERFECTION is"...
I've been training slow since I started riding a bike...? It doesn't work, i'm still flipping slow! 😂😂
😂 Maybe you need to go _even_ slower??!
@@gcn Fantastic video. Inigo was very insightful and informative. Interesting parallels with 'body building' training processes - I.e. working energy systems and using steady state cardio (Z2) / deload weeks to clear lactate after periods of high intensity training.
Can confirm! Cheers fellow slow rider!
@@gcn Any slower for me and I will fall over!
same - cycling for a month and ave speed is still 12 mph 😆
The basics he is talking about is the same knowledge passed to me by older racers when I raced in the late 70’s. Fascinating.
Thank you for doing this!!! I Have been doing 3-5 hours of zone 2 for the past year because of Inigo San Milan. I also have been doing GCN workouts for almost 4 years. Love this!
Absolutely fascinating! Please make more of theses videos on sports performance and science.
So glad to see Iñigo over here. I've been doing only fasted training for over a decade. It shaped everything I do and I can't imagine doing otherwise. I'm always trying to convince clients that part of their belly and their energy problems are one and the same but it's so hard to break people from the "fuel your workout with products" mentality.
I think this was my favorite video you've done to date. Not only did it have a wealth of easy-to-understand information for all levels of riders, I found Dr. San Millan a joy to listen to. He explained things so well! I'd love to see more content like this on the channel. Well done.
Great video! Have been quite a few videos on training advice recently. Why not pull it all together with a video or two on training plan design, that brings together all the insight from this video, the strength training video and your combined experience? I think it would help a lot of people, including me!
Yeah periodization would be a good one.
thank you for taking the time to bookmark the "chapters." Loads of help!
What a fascinating and useful interview. Well done, Simon! (I am a big fan of lots of Zone 2 work.)
It's the trickle down info that helps us improve our lives that makes cycling so cool.
Especially info that improves this vehicle we use to cruise through life, our bodies.
Thanks for the lesson, very nice.
Keep it fun folks!
I'm not a biker but I've run some trail marathons and the zone 2 work was such a nice, sustainable way to train. Over time you get faster and faster at that lower heart rate and it's amazing how far you can travel in 4-5 hours when you dial that in.
Oh boy I can't even imagine training any different at this point. Especially for running it's so much higher impact. A good 10+ miler steady state effort is just a dream. My favorite workouts during the week for sure :)
this could be the most informative and life changing GCN. video ever..
Some high powered concepts that were very well explained. Thanks GCN
Really please you posted this up , definitely feeling wipe out with intense rides and now I know a super way with all the advice to get back in the game ❤🚴♂️
Great topic! Doing Z2 training for over two years, absolutely love it. My experience - first you need patience, because you ride / run slowly and it takes time to get better. Second, you need to get the zones right - preferably by blood testing during excersise. Third, combine with interval training. And get yourself a qualified coach for that. @gcn keep doing this type of content
This video inspired me to have a go! Takes a load of concentration and self control to sit at z2 for over an hour! Let’s hope it works! Truly cycling inspiration thank you
Golden advice No endorsing 5k bikes. All man no machine. Love it!
Great video GCN. Ignacio is the man! For anyone who enjoyed this, I'd highly recommend listening to Peter Attia's podcast with Ignacio. There are actually two. It offers a really big deep dive into all this stuff if you're interested in the complex molecular details.
Indeed, I was going to mention his discussion with Dr. Attia as well. Truly eye-opening stuff.
There is over 3 hours of San Milan on the Peter Attia drive podcast, good listening for a long Z2 ride
Love hearing from professionals in specific fields as they relate to cycling. Thank you GCN for being the conduit, channeling us this information. Great interview. Si, Christchurch, NZ.
Great content. I have been following Iñigo and his Zone 2 training for about 3 years now. Just awesome. So you have some idea, my Zone 2 HR is between 75-81% of my max HR and 200w. Blood lactate averages about 1.7 at this level. Sleep or quality of sleep can affect these numbers as well. Weekend worrier, former racer
@@uberpekes Percentage of HR isn't a realiable indicator of Zone 2 because other confounding variables influence heart rate (e.g. level of fitness, how fatigued you are, how well you slept, whether you've eaten recently, etc.). The talk test is more reliable. Another great test is aiming for the highest intensity of exercise at which you can still breathe through your nose (assuming you don't have any difficulties breathing through your nose normally). 🙂
@@uberpekes Talk test and breathing test are really more useful and effective than HR 🙂
@@james5150 great tip with the nose breathing. Thank you.
Awesome vid with some great info. As other's commented, we need some 1-1.5-2-3 hrs zone 2 training videos for this winter.
Very interesting interview! What I would like you to explore more is how to actually do zone 2 training efficiently. If you ride in a bunch or just with a few mates, you are either in the wind or on the wheel, so it's not easy to keep that pure zone 2 all the time. Same if you are in an area with mountains, it can be hard to keep in zone 2 going up and actually hard to get over zone 1 on the descent.
Turbo trainer to the rescue?
I can’t do Z2 with anyone else. Too anti-social! Indoors is good. Inigo SM suggests a minimum of 3 sessions of 90 mins a week will result in improvements. I now do these on the Atom Wattbike and clamp my HR with ero mode (power) so I get the full 90 mimutes every time, no fluctuations like I would outside.
@@inz_uzi I live in perfect climate, so don't really want to train indoors, but yes you are right this is much easier on a trainer
@@inz_uzi I'd rather give up riding than turbo train, it is cycling but with all the good bits taken out! 😂
@@beankeef22 It's up to you to decide what is more important: having fun or having "results" 😀
Well that was a real eye opener. A scientist with a yellow jersey behind him telling you to go slow, I'm taking that advice and running with it. Well maybe I'll just walk at a fast pace with it! Thanks for the great information GCN.
Great interview and very interesting. I have heard of intermittent fasting but would like to know more about the fasting referred to in the interview and how it works for cycling. Excellent videos as always. Keep it up.🎉
What an awesome topic and interview! I have a horrible time riding in Zone 2. Im encouraged by the head of the racing team I’m on to put in more time at zone 2, and I just slough it off and hit another HIT session. I’m 66 now but in my youth I was an international level track and field sprinter - 100m, 200m and 400m. I had the personal moto ‘if I can’t go fast I don’t go’. I hated long slow runs then, still do. My brain says I’m a greyhound, but my heart now says no you’re not. This interview has given me a new perspective on zone 2 riding and much to think about. Thank you Simon and GCN for doing this program.
This is absolutely fascinating! Thank you for this. I have MELAS, which is a mitochondrial mutation that means I don't produce energy properly. I have to ride exclusively in zone 2, but it really helps
Uhh wish you health 🙏🏻 keep riding.
Just great to be reminded that zone2 really does work. And endless HIT schedules end in tears always! And heart rate training is not obsolete. All the measures are good to utilise when they work best. Thanks very much!
Great interview! Interesting stuff. I've seen huge improvement this last year in overall fitness by doing a lot of zone two during the week... with a bit of intervals or hill climbs added in... but mostly zone two improving my baseline.
In my opinion this is the best and most interesting video I have watched. Great job guys
Glad you enjoyed it!
I found moving to a lot of z2 made a lot of difference when I used to run; people would wonder why I was joining a slower group, but come race day it showed its value. I found it worked less well with cycling, because my musculature (or lack thereof) meant I could reach a point where I couldn't push the pedals despite my HR still being very low. I'd be interested in thoughts on how the muscular requirements of cycling compared to running may change things.
The talking thing, either being able to talk or not while pedaling along, was a good point.
I will chat while riding in a group...........and some people can hardly say a word. I dont realize how hard they're working even to stay in the draft. They will finish the ride and say it was the hardest ever. It takes miles and miles to make it work.
I never took the time to do this when I was younger.
Very interesting interview! Thanks for that! One thing that really struck me was when he says that if you break the zone 2 “mode” by going too fast for a short while, it may take up to 30min to get back in the right mode… I’ve been feeling that exact scenario many times in my training without being able to explain it. If I let my guard down for a while and let myself slip into a faster pace, after going back to a slower pace again, it doesn’t feel the same anymore. As if my body is activated in another level and where my heart rate becomes much more responsive and sensitive to hills/or other change of pace. Hard to explain. Anyway… cool stuff and thanks for bringing us this good interview!
Everybody should watch his two podcasts with Dr. Peter Attia, they are amazing.
I've definitley improved by doing more zone 2 work, my only problem is self discipline - I go out for a steady ride and always end up thrashing it half way through.
;0)
Thank you Inigo for being so generous sharing this information, and to GCN for making. Super awesome
Zone 2 riding still requires progressive stress and rest. The single important variable is TIME. So you need to progressively step up your weekly Z2 time in a stair-stepped pattern for, say three weeks, then take a down week for rest. But you need to keep increasing Z2 to get increased benefits. But with Z4, it’s complex but more related to intensity levels and repeatability. But just doing the same Z2 every week is not optimal. Increase your time progressively to build base fitness and take rest weeks regularly. I typically advise people to do Z2 alone as it avoids competitive situations where intensities get too high. And flatter courses are generally better as they avoid high intensities climbing and zero descending. Just my two cents.
Dang someone adding in peridoization to training somebody knows what they are doing. Base, Hills, Tempo, Taper, Skills, Strides, Race. Periodization.
@@aethylwulfeiii6502 Thanks. I wrote the first periodized training programs for the US national team back in the early 1990s. Heart rate-based as we didn’t have power meters yet. I learned about how to periodize endurance programs from weight training and Scandinavian cross-country (Nordic) ski coaches. Nobody had systematically periodized cycling training yet or integrated weight training with cycling in-season. If anyone was weight training, they did it in the winter and promptly lost any gained strength in the spring when they stopped. I was the first to use computer spreadsheet programs like Excel to create customizable periodized programs that I could adapt to any individual or race schedule. I even created double periodized programs for one of my masters athletes who was a world-class age-group cyclist and Nordic skier and she needed a custom approach.
Just a reminder that your Z2 will change quickly if your are new to cycling. I started with a 226w ftp exactly one year ago and now i do my easy endurance at 200w (105-110bpm). Buying an indoor trainer is what really changed everything for me!
Really interesting video. Would love to see something on how to plan outdoor rides to target different training goals (not all of us have space for an indoor trainer at home!). Living in Devon I have a lot of huge hills all around and struggle to plan something that doesn't push me into zone 4 within the first 30 minutes
Same issue here in SoCal. I think some of this is more easily done on the trainer, then go hard on the weekend
Just slow down. I also live in SoCal, and while I am pretty far above average for power, you don't have to use it all the time. Put it in the lowest gear you have and enjoy the view!
That was a banger of an interview. chocked full of great information and solid ideas. Thanks Si and Dr San Milan
Interesting, I used to do a lot of running before I got into cycling and the "barely able to hold a conversation" has been the target point for run pacing for training for as long as I'd been keeping up with my fitness. Seems like it's a pretty good "universal" rule for most cardio based sports.
An equivalent target is the highest intensity of exercise at which you can still breathe through your nose (assuming you don't have any difficulties breathing through your nose normally). Again, another target point used by runners for decades 🙂
Another is that Z3 is where you can start to hear your breathing, or that someone else can.
I like your video. I watched the two hour podcast with Dr San Millan and Dr Peter Attia. It was great insight. I would suggest you watch it, as the "ZONE 2" they are discussing is not what cyclists call zone 2. I've now been doing this middle cycling "ZONE 3" , NOT SWEET SPOT AND NOT ZONE 2, for almost a year now and it works very effectively. How I interpreted it was you need to stay between 70-80% of your maxHR while not using above threshold power. Complicated for rolling hill style outdoor rides. It means throttling back to your easiest gear on some climbs, and even dropping the cadance to stay on just below your sweet spot on the climbs, but then actually riding harder than you usually would on the descents to stay inside the magic 70-80% maxHR, or what they call Peak Fat burning zone. All my solo rides are now done like this and sometimes I add in the threshold for the last 10-20 mins to get the benefit of the high intensity. I do 100-250 miles a week over 4 days. I use to get dropped by the ex-racers and triathletes on the Saturday group ride, but not anymore. Average speed in the group ride is never below 21mph, sometimes the middle hour is 25mph.
Really loved this kind of content from you guys . Getting into the medical with at home tips from a phd to help diagnose your zones in training. And the detail . Loved it great questions. Maybe he would be down for some follow up questions from viewers presented and sorted through by gcn
Listen to Peter Attia's excellent interviews with Dr San Millán if you interested to dig deeper 🙂
