I have been fortunate enough to have guidance from Dr. San Millan. I am not a professional athlete, but he treated me like I was! He genuinely cares about your success.
How is it you were guided by him? Did you go to his lab for testing?
Zone 2 training is wonderful. At least 80% of my training is in zone 2 so at least over 10 hours a week. It’s so important for all skill levels.
10 hours is a bit extreme for health reasons alone. Are you training for something specific?
Their name is Marathon5151 so I'm guessing they could be training for a marathon 😅
@@GabrielBacon Currently training for the Marine Corps Marathon and getting my time under 2:35. I then have the Disney Marathon in January and will plan a few more for the spring. I run about 5-7 marathons a year on my quest to run all 50 states in under three hours.
@@GabrielBaconExtreme? I do 10-14 hours a week and I’m training for nothing but being in the present moment. However, if I want to compete in something I can, but how silly it is to “pay money” to compete in some endeavour to have someone pat you on your back and tell you “good job” or have a need to seek validation or worse motivation to do something.
It’s far more than wonderful. What he’s describing here is the holy grail of the most efficient training in the world and it’s awesome.
And yes, the person saying that your training may be extreme obviously did not see that you are at the level of an athlete. Nothing extreme about that. Your training is normative for a higher leveling of cardio health and performance.

LOVE this video.
I had breast cancer and got myself through it by cycling every day and five years later am still doing b that. (And running and swimming) Oncologist’s main advice:”exercise!!” So I did!
Having listened to the whole thing I now feel like I’ve done a year at university ;-) Packed with information delivered in an unpatronising way. Perfect. 🎉
I'm 11 weeks postpartum. I've found that walking with my now 15lb baby in the carrier keeps me in zone 2 (zone 3 up hill). One of the few times I get to listen to long form podcasts too. I'm really focusing on enjoying this time before he's too big to carry
Progressive overload as the little one gets bigger!
Please watch the weight of the baby and follow the chart . Also human breast milk is the best food for babies immune system in the future and microbiome. I am Obestetrician very conscious about my patients weight and their babies. Prevention of diseases is better than the cure. Health start in utero and type of delivery. Hope this is helpful, if not I apologise and sorry.
@@samieramohamed2467 I appreciate your concern but all is well here. I exclusively breast feed, baby's length is proportional to weight gain, and his pediatrician is happy.
@@RXP91Milo of Croton 😄
@@RXP91 that was hilarious to me
The information in this podcast is so helpful! I realize that I have been beating up my poor mitochondria with lots of extreme daily exercise, both cardio and resistance. Thank you so much, Simon and Inigo. You both are doing such a great service to people.
@TheProofWithSimonHill I found it very interesting that he defended a low carb diet as a tool to get your mitochondrial/metabolic health back on track! Going low carb has changed dramatically how I feel. As I continue to surpass my health goals it will be Interesting to start adding back in some healthy carbs and see how I feel. I also plan to start adding in more zone 2 training after watching this, along with the zone 4 that I have been typically doing to this point.
He disproves so much of the “longevity expert” stuff with real science. Invaluable ❤
Wow, I was searching for zone 2 content so I could learn more about this and this was really the best and most helpful of all the videos I've watched. It truly makes a huge difference when you have an actual expert and researcher in the field, as well as a world-class interviewer (absolutely great questions!) than to have a somewhat knowledgeable RUclipsr, but who doesn't go as often on RUclips into this much depth. So thank you very much for this!
This is quite possibly the best of Simon's podcasts ever!! There are so many gems in this. Thank you both!!
This is the best interview with Dr. in Nico. Thank you Simon for asking so many intelligent, on the nose questions and to both of you for getting down to where the rubber meets the road in practical advice about training in zone two.
Great presentation. At 1hr 30:00 is a great reminder that the populations moving alot and eating 65-70% carbohydrates, 15-20% protein & 10-15% total fat intake. When fat is kept pretty low the insulin receptor sites wont be fat saturated. P.u.f.a.s now especially fried foods are I think one of the main reasons the receptors get altered/interference. Pure saturated fat from memory gets metabolised more instantly like mct oil. Its also why dling experiments with overfeeding subjects with 200cals a day of 90% cacao dark chocolate & organic coconut oil would have different metabolic outcome with 200cal of canola oil.
When pre Westernised Japanese ate lots of white rice and not too much fat alongside it they didnt get obese even on 300g+ carbs a day perhaps 60g fat and 120g protein example etc.
Now we take the same 300g carbs from daily Kfc and oreos and fatty icecreams say 200g of fat with the same 120g protein the massive increase in fat increased total caloric load plus was loaded with toxic oils which increase insulin resistance.
Outstanding work. If this content was only available in a book, I’d buy it instantly.
Thanks , up to the point. Good explanation about zone 2 which most talk about as if we know it. Also good explanation about lactate. He is a good humble scientist no inflated ballon bubbles ego which most speaker have super inflated ego and self wasting our valuable time to learn but always sell themselves in a market. Amazing high standard interview by both host and guest . Keep the high standard and don’t sink as others. People wants honesty, clarity, simplicity and down to the understanding of lay people. This comment from professional medical doctor who is the more I know and learn the more don’t know.
I just found your channel and can't get enough of your videos. Very informative,. It looks like you aim to be as inclusive, thorough and impartial as possible. You also have the most insghtful guests. Top of their field. Thank you!
Amazing questions, Simon! I've seen multiple interviews with Dr Inigo but for me this one was the best, simply because it came from someone who is not an MD or DO or interested in one aspect alone of his work.
I've been doing something approximating zone 2 trainings for about half a year and I can say my recovery from a hard Z4 or even Z5 is less than 5 minutes compared with last year when it would take me 15-20 minutes to recover. Now I have also a lactate meter to try to figure our where my Z2 is precisely, yet that depends also on how rested you are or how fatigued your muscles are, and Dr Inigo is bang on with the perceived exertion. It happened to me to be able to do Z2 at 200W in one day and on a different day after a hard bike session in weekend I was already at 2.4-2.5 mmol of lactate at the same power, yet it felt way harder.
Thank you for the great interview!
46:59 “I’m not sure if I articulated that well”
That question was articulated exquisitely!! Doubt it could possibly have been articulated more specifically or more clearly…
An amazing discussion. As a cclinician who utilizes VO2 testing in my cardiology practice, it has been exciting to incorporate the information gained from this test to help our patients in cardiac rehab and pulmonary rehab. I too have had questions about testing , benefits of zone, directed, exercise, supplements, etc. San Milan seem to keep saying “a great question“ because brother Hill kept asking great questions. Questions that I wanted to know or hear discussion about. Simply an excellent podcast. I subscribed :-)
Totally agree, better interview than the Peter Attia podcast
Have you seen improvements in LV EF? I'm 38, and for an unknown reason was found to be at 50%, Im not hypertensive, 110/60-124/77 range BP during the day, have a 0% calcium score, never had a heart attack. I don't understand why I'm borderline heart failure at this point.
Simon you ask intelligent and well thought out questions and don’t ignore the basics either making these conversations extremely valuable. Cheers 👍🏼
I'm about to watch this - my favourite type of podcast! First, I feel compelled to say that I think the host is the healthiest and most glowing person I've ever seen (and I'm 57!) He exudes health and wellbeing. Impressive!
I wish Inigo would write a book or article for those of us who aren't athletes. Put it all down in one place. His stuff is so great.
@@TheProofWithSimonHill The clear description of the talk test. I'd like to know more about the trade offs. I'm not interested in being an elite athlete. So if I do an extra hour a week in zone two what benefit does this get me?
@evanhadkins5532 the more you do, the more benefit you get.
@@evanhadkins5532you’ll get no benefit from that type of time in zone 2
He’s the best
@@MarkMetternichPhotographyLLC Thanks Mark
This is the best video with Inigo I've seen so far, thank you so much for the quality of the questions.
Thank you for your time, Dr. Millan!!
Thank you guys for this. It is priceless. Your gratitude towards one another at the end of the video is wholesome. And you deserve the credits. You're changing lives with this content Simon, and Iñigo it is really admirable that you dedicate yourself to sharing your knowledge through the divulgators like Simon or Fissac in Spain, we're lucky to have access to such scientifical wisdom.
I've been taking notes and I think it was all very clear. If I ever have any doubt, I'll make sure I'll share them with you guys in case you meet again :)
Bless you!
I really am excited about getting into some of the Zone 2 training.
I remember Simon made an episode on this not so long ago and was constantly remembering myself I had to watch it but I never really made it. Now with Iñigo it was a must-watch. I'm sure I'll enjoy the hours of Zone 2 walking heheh
Dr Inigo San Millan - WONDEFUL! WELL DONE SIMON HILL!
Great discussion tying together many different fields of interest (biochemistry, metabolism, mitochondrial function, sports medicine, ICU recovery).
I deep dove into his publications last night.
Definitely a podcast to listen to multiple times.
Thank you for the update on the lactate shuttle.
A job well done! Your complementary comments and pertinent and clearly articulated questions culminated in an immensely valuable and practical guide \ manual for a healthy existence and, once again, brought out the very best of Inigo San Millan. Be well!
This was a really interesting topic, and you both were awesome at reviewing and summarizing the information. Thanks to both of you for sharing your time and expertise ❤
Amazing episode. Z2 has truly changed my life. Especially when it comes to the stresses of life. Thanks for going deep and scientific, gents. Truly wonderful.
I haven't listened to this yet but I wanted to say thank you so much for this podcast!!
You have the best questions in the business!
Wow, this was a bang. Scientific background and practical application. Everything related to exercise hits the spot for me. I’m curious to learn more. And Simon, your qualities as a host are beyond excellent. Summarising, asking simple questions the listeners might have, challenging believes - you evolved so much.
Thanks Simon, eye-opening interview!
Although I've seen several other interviews to Iñigo before, this is the best ever!
Well done! Clearly, even if there were "free healthy lunch", it would never be as helpful as a "free zone-2 hour"!
No doubt about it, this live was a game change for me in any way that you can imagine. Thanks a lot for that.
There's an important part from 2:19:02 to about 2:21:00. Simon asks if you're in zone 2 if you do maybe resistance training and your heart rate passes through the zone 2 range, it cumulatively counts as zone 2. Dr. San Millan basically says no it does not.
Heart rate applies as an approximate measure of zone 2 _only if it is done during continuous, steady aerobic exercise._ The zone 2 benefits come from the muscles working for a sustained time at an intensity that uses the mitochondria to burn the most fat. The heart rate is just a surrogate measurement of the important part- the muscles working continuously.
A panic attack or horror movie can put your heart rate to 130, but your muscles aren't doing work in the chair. And if you've been doing resistance training, your body is just catching up for several seconds of high intensity work, not supporting minutes of mitochondria-building medium light intensity work. As Dr. San Millan says at 2:20:07 "it's a recovery phase, it's not a metabolic phase". In both cases the heart rate is meaningless even if it is in "zone 2" because it doesn't represent that type of muscle activity.
When your muscles are working at a steady pace, warmed up/vasodilated, and calling for oxygen for several minutes straight, your heart will increase both speed and strength of contractions, and that's where heart rate actually means something, it can approximate what metabolic phase you're in because the heart rate comes from the metabolism itself. I've seen people make this mistake, if your watch/app says "zone 2" but you're just passing through instead of doing it for 10+ minutes, you're not really in zone 2 even if your pulse is.
From 2:10:00 to 2:10:30 (and earlier in this podcast I think) he seems to imply you can get zone 2 benefits at 30 minutes (maybe even 15 minutes at 2:05:30 because it takes that long to start up) but it's better to go 60 minutes or so continuously.
Just found this channel. I am now 61, have been running for several years, but now coming off a foot injury. Starting up again I decided on Zone 2 or low heart rate training (MAF). My maximum heart rate is 177bpm, MUCH higher than any calculations indicate for my age. Based on the “calculations” my max zone 2 is 140 hbm, however, on the conversation “test” that can be done up to 154 hpm. The 140 currently results in a lot of walking but not for the 154 so I continually wrestle with the correct zone 2 level for myself.
Fascinating and informative conversation. Thank you both for your time. 🙏🕉
Fantastic podcast !! Thank you so much for it, I am trying to understand better all aspects of metabolic health as part of my health goals and the info you got here helps me tons!! You asked the exact issues that are around my head and also made clear the complexity of the topic; now I got to get back to BIO 101 to remember the metabolic pathways 🤣 Thanks again and keep up with the good work!!
Phenomenal content ! Thank you Simon for your exquisite quality of content., your kindness and your style of interview. Dr San Milan is amazing Your podcasts with Dr Dayspring changed my husband’s health trajectory as we found a stellar lipidologist who walks the same line as Dr Dayspring and knows him . Much gratitude always !
Damnn! You really brought San Millan! How amazing.
For Spanish metabolism adepts like me he is a legend.
@@TheProofWithSimonHill Oh man I'm loving it!
@@TheProofWithSimonHill Okay Simon, I've got some doubts for you guys if you ever get to meet again. Or you can make these questions to another person if you like.
1. Iñigo said that for teamsports athletes, the planification of training might be slightly different. I guess it is less Zone 2 focussed compared to athletes like swimmers or runners.. Is it because it isn't efficient for teams to dedicate their (sometimes limited) training time for the metabolic aspect when they have so much tactical and technical aspects to train + physical that is more focussed on strength and prevention programs? Would the athletes still benefit just as much of Zone 2 training time, maybe isolated from their teams training sessions? Is it that much benefitial, considering their kind of physical deployment (change of directions & rythms & sometimes long sprints, but still with a good amount of runs that aren't extremely explosive)?
2. Is it counterproductive for people that want to build another type of muscle fibers (such as, let's say, powerlifters), to train in Zone 2 and therefore develop more / differentiate their muscle more in a slowtwitch fashion?
3. Whenever an individual's respiratory system is compromised, would that compromise the utility of the 'talking test' to find the Zone 2 (/any other Zone) of that person? What would be the tips to avoid false results? Is there any adaptation to the test/ other tests that would work too without needing the lab exam?
Much anticipated! Thank you 🙏🏽
This is the best nutrition video ever. Finally TRUTH I have watched so much garbage, lied to for decades. Thank you
GREAT CONVERSATION. Best podcast i've ever watched on the subject. Dr Iñigo is so interesting and humble. And the questions were perfect. Congrats
Can't wait for the second podcast with Inigo
Insanely incredibly valuable information that everyone should know.
Thank you for another great interview, I always appreciate and look forward to your show. Greetings from Okinawa! 🌺
Great listen! I bought a treadmill specifically for JUST Z2 and have yet to use it for that. Oddly enough, I now enjoy hiking and run+walk on it as well as hiking bootcamp. Now I'm convinced I was right in the beginning and must incorporate Z2 into my workload. That many minutes will be unattainable though.
Amazing and awesome discussion. Answered so many questions. The interviewer did an awesome job and interviewee was of course par excellence!
Thanks so much for that sensationell Podcast.Unbelievable to get al this Information for free…🙏☺️🙏
You guys are gold! Thank you.
Wonderfull and very interesting conversation - and I loved when he mentioned the core question: What causes the mitochondrial disfunction? And the important conclusion to improve mitochondrial numbers and Health is exercise - that just sounds as a very good message - keep moving moderate exercise is important for everybody
Fascinating discussion, lots of details and actionable information. 🎯🙏
Brilliant !!!!!! Circulate widely....
That initial story was incredibly inspiring.
well thought questions. A comprehensive session. Thank you .
Brilliant exposé on z2 ! Thanks 🙏 guys
Loved this episode. I just happened to come across it. you asked excellent questions. I subscribed right away.
This was brilliant as always. I learned to much. Thank you to you both.
Great video- a lot of the questions that I’ve wondered about were addressed here.
Thank you, Simon, for such a wonderful, detailed, insightful session. It helped me to understand what actually Zone 2 means in terms of science and practical implications.
Glad you found it helpful!
Today I went for a 5km run around 25min listening to you, did 23km on zone 2ish in 2h29 👌
One of the best segments. Inspiring and genuine, authentic. Great contribution to the world, guys
Glad you enjoyed it
I’ve watched and rewatched most of the Zone 2 podcasts published. I have the theory down now but what would be really helpful is a short demonstration with Iñigo watching and commenting on the demonstration. Because the margin for error is relatively small (10 bpm) it would be good to see what he means by the ‘talk test’ indicator. Thanks for adding to this growing area of knowledge.
Check out some of the GCN videos with Inigo, as it’s described in more detail there.
I would be careful with HR as Z2 indicator. Switching from summer to autumn my HR is now easily 10 bpm lower just because of temp. LT1 is around upper Z2 is around VT1. VT being ventilatory threshold. It is basically where you start to breath deeper because of higher O2 demand. Talk test refer to that. You are still able to talk, but the other side would notice that you are exercising..
@@danb7808 I use a combination of indicators. At the moment the main one is the ‘talk test’ or what i believe it to be. Secondly, using a chest strap and the point just before the heart rate takes off and becomes out of control. So the heart rate is at its highest stable point, for me it’s around 115 bpm. The heart rate figure will increase over time so this needs to be remembered.
I’ve heard two slightly different descriptions of the ‘talk test’ and that’s why i’d like to see a demonstration. You really only need to be out a little on the talk test to be out of your zone 2 band, it’s a very narrow window.
Watching way too many videos and doing absolutely nothing about it, just watching videos. 10 bpm is definitely not a relatively small margin of error. I just made it smaller for you, get on bike and cycle 120-125 bpm. Ride in the morning upon waking when your resting heart rate is not raised from a whole day of sun, caffeine, stress, talking, thinking and emotional regulation. Learn how to control your thoughts and emotions to keep your bpm steady, keep your cadence high, don’t cheat with low cadence. Ride at least 3 times a week for 2 hours and once a week for 4 hours (in this ride you should see your bpm raise and it will be a test overtime of your bpm stability)
@@HigherInfluence Good you don‘t take a fixed HR rate. I never really did the talk test, but am slightly above where I need to breath deeper/faster.
Your best guest ever🎉
It's funny when you think about Jim Fix who popularized running,for fitness, and who said "anyone who could complete a marathon was immune from heart attack" before he promptly died of a heart attack while running.
Then you tour the blue zones and she all the little old ladies over 100. Then I think about my older relatives, they're all female in their late 80s and 90s and have outlived multiple "fit" husbands while not doing 1 minutes zone 2 training in their lives. Funny that 😅
Problem is runners eat a lot more due to the exercise and usually eat a lot more crap that hurts their arteries. Even though they look fit, on the inside they have lots of damage. That is why I switched to a whole foods plant-based diet.
@@Marathon5151This. Spot on. So many ppl miss this fact.
Even fit ppl get heart disease, as many studies show. Many runners eat tons of saturated fat as a result of eating tons of poor quality calories. Many fit pol can have a high Apoo B. So many ppl in the low carb community wrongly think as long as they have a six pack they won’t drop dead of a heart attack. Such a wrong and common misconception.
@@BlahBlahPoop617 Agreed. You can't outrun a bad diet. My father-in-law has run over 70 marathons, but thinks because of his exercise that he can eat a couple extra burgers or sausages in a meal. He then wonders why his cholesterol and blood pressure numbers are getting worse. I keep telling him to eat more plant-based and get rid of the saturated fats.
Jim Fixx had poor genetics, and that belief about running 'allowed' him a poor diet. You can read a bit about him in the book 'Eat to Win' by the tennis Doctor Robert Haas (not 'Eat to Live' by Fuhrman). You could also use Jack LaLanne as a data point, who died at 94 after a lifetime of fitness, rather than Fixx.
@@BlahBlahPoop617 saturated fat?! most runners eat a shitload of carbs.
Glad to hear him covering NMN, rapamycin and resveratrol at the end there as my opinion is starting to lean heavily in the direction of just leave all that sort of stuff alone. Also 300-600mins a week is going to take me ages to get too because my understanding was you should only increase your range or duration by a little bit at a time and I struggle to do the 150 per week
Man, I am hoping this information will help me pick the lock of my training for martial arts. Just started 2 years ago, currently 46 years old, and just can’t figure out of how make more significant improvements in my endurance during sparring. I think building this zone 2 base vs thinking I can just power through until I get better (likely in my high end zone 4 or greater) might be the change I need.
Also, your line of questioning during the interview was very much what I wanted to ask as I was listening. This episode is another gem, thank you as always!
This is an excellent 👌 conversation . Tq guys .
Feel like I've learned so much after this one!
Important topic-- much needed and well-executed. Thanks to all making it possible!❤
Amazing Ty for podcast
Super important what he said in 1:44:50, because people think HR up in his watch, they need to stop or walk... if you feel you can talk and HR is little higher on your watch, That Ok... You are in Zone2 Yet. Good Interview
very good set of questions. Amazing interview
Great stuff, loaded with infos. I swim 30min 4 days a week, now I know I need to bump it up to 60 min 😅❤
Thank you so much
I just finished watching this great episode. I really enjoyed the very practical questions you asked that we part-time athletes struggle with.
I just had one unanswered question related to the amount of exercise per week. As a triathlete we practice different muscle groups per activity. Can we add the time spent in different activities up to come to the 300 weekly minutes or is this time minimum set per activity discipline?
I actually listened to your interview of Dr Stacy Sims before this one and now I'm a bit confused. She doesn't seem to be in favor of zone 2/moderate intensity cardio for women, especially that many hours a week. I don't know if this whole conversation only applies to men because the studies were done on men and excluded healthy premenopausal women as they often do, or what do you think Simon? Is this something that's gonna be covered in a future episode?
Best podcast I’ve seen! Thx 🙏
Thanks for listening
Ok that is truly good stuff when directing immediatly to some parts of the video .. ❤
Would of expected he would of said creatine when you asked about supplements. Be good to have dived into the food part more, when and what to eat to optimise zone 2 training. Great episode as always.
Hi Simon,
I'm a big fan of the podcast! I listen to you, Gil, and Chris almost every time you release a podcast/episode. One question about this podcast:
I'm an recreational ultramarathon runner, and everyone in this sport consumes carbohydrates for fuel - almost exclusively. And generally speaking, unless you're an elite level runner, the majority of your run will be in zone 2. If fat is the preffered macro on a metabolic level - why then isn't fat the preferred macro for ultra running?
Thanks for everything you do!
Senya
Good advice is supplements don't take if messes up other pathways. Too many supposedly supplements are being listed, trending, I will save my money eat real food. Glad 150 minutes a week is low as I walk hike hills hours DAILEY; likely in zones. RT I do daily as I remember being on a farm in the countryside which was a natural active 7 days a week lifestyle. Enjoyed this discussion with a passion. Thankyou both. Please another podcast, part 2.❤
I have enjoyed this so much. Great content thank you.
Glad you enjoyed it!
thx iñigo! tu trabajo es increible, pero quedaria enterrado si no lo compartieras!
Thx for sharing your knowledge through podcast and new media, otherwise we wont be able to reach it and learn from it
Thanks. Great running company.
Dr San Milan is very persuasive I have to say. But he is asking a lot. Not even Peter Attia in his Centenarian Decathlon asks so much of his patients in terms of time in Zone 2. He mentioned that sustainability in exercise and diet is important and everyone would agree. But wow! 600 minutes plus per week plus Zone 5 plus resistance training. Thank you Simon for exploring breaking it up into two 30 minute sessions. That seems much more sustainable especially if it is broken into two modalities to keep exercise interesting. Thank you as always for an informative and beneficial podcast.
I do between 600-840 minutes of zone 2 per week. If you do that much zone 2, you’ll realize the benefits overall much greater than the ones you are chasing. Wtf are two thirty minute modalities? That’s a joke in any type of endurance training. Most people are never able to make the sacrifices and handle the suffering needed for even the things the claim they want because keeping something “interesting” is more important. If that’s how weak your psychology is, then no offence but you need more zone 2 training. Put in the work or don’t.
Thank you for your opinion. I disagree. Exercise is never an all or nothing proposition. Something is always better than nothing. Pleased you are so mentally tough. Good for you.
@@jimpatek6244 You are free, free enough to make choices. Just don’t think there aren’t others making other choices. You see, you call it “exercise.” You do it for health benefits or for some goal, milestone in the exercise you are doing at which point you will feel some sort of validation. But remember, that we are spiritual beings having a human experience and in that 4th hour of one of my zone 2, non stop cycling rides, I am in the “present moment” with reality. There is no outside programmed belief or internal insecurities, conscious or subconscious that I am validating or chasing. I just am with reality and in 4 hours non stop, enough thoughts and emotions pass by and I observe them, not attach to them, let pass, it’s like active meditation and I feel no suffering because I can sit in the moment and experience it for what it is. The “exercise” or “health benefits” from Zone 2 cycling are simply shallow fodder and if that’s all you get out of it then it explains what you are after and your reasoning for it and thus you need to make a compromise and maybe devote more hours to something pleasurable because this seems painful to you. It’s not to me.
Great discussion.
I completely agree with ISM, anaerobic threshold is a total misnomer. My oxygen consumption increases perfectly linearly with power up to VO2max. All energy comes from oxygen (maybe short of some anaerobic to compensate for efficiency degration). Anaerobic begins to become significant above VO2max. Even Coggan got that one right already in 2003 when giving his training zone names above FTP.
It can’t get any better. Excellent interview , a very knowledgeable fascinating guest. Thank you Simon 🙏🏾🙏🏾
Great interview Simon!
New subscriber here. loved this discussion. Thank you.
Some athletes preparing for the Paris Olympic Games are producing greater output from ketones at high intensity than from glucose. Fat adaptation takes several months which is where most studies fail to demonstrate this in a laboratory. It would be interesting to see Dr San Mallán conducting side by side trials with athletes metabolising glucose, vegetable fat and animal fat who are fully adapted to ketosis.
After having listened to this excellent podcast, I have no choice but to subscribe to the channel.
Did I say ´excellent’? I meant mind blowing.
I knew this would be the clearest summary of ISM's thoughts. Future questions!
1) Does the modality of exercise have an impact? e.g. running or elliptical trainer would build mitochondria capacity in the whole body. Cycling mostly in the upper legs. Is one superior to the other? If not why not?
2) As you get fitter doing Z2 is actually very taxing on the body. Stephen Seiler's work has shown that most athletes don't actually spend a ton of their time in zone 2, but rather Zone 1. ISM's thoughts on that? (I can link to a Twitter thread where Seiler mentions it if needed). e.g. for me I'm up to 250w on the elliptical and 8:00 min miles running. That's a ton of stress on the body at the volumes he's talking about for a non elite
3) Intensity for duration. Seiler calls this extensify. Walking was mentioned a ton in this pod. Thru hikers who regularly do 20 miles a day get adapatations in vo2 max and resting HR that higher intensity zones do. There's clearly a point where low intensity but multipled by a huge volume can achieve the same. Zones are specific to a set duration. Your zone 2 wattage in hour 1 will certainly be Z4 at the end of hour 2 if you're not elite. What's ISM's views on that? The talk test doesn't work in these scenarios.
@@TheProofWithSimonHill Hi Simon, it's not that I can't pass the talk test (zones are lab tested and verified with field tests). But doing all your runs at what runners call "Tempo" pace is very taxing on the body - but I guess that's the fundamental difference between running and using cardio machines/cycling which have no impact or eccentric aspect so easy on the body - would love to get ISM's thoughts on that.
Totally shocked to hear that zone two is so narrow and how wrong we can get it by being outside that.
Please could you recommend a good way of finding a reputable place to get your zones sorted out/lactate tested-perhaps questions to ask, qualifications to check and then precisely what to ask for when you are there?
Thanks you so much.
I wish so much more people would listen to this. I will be spreading the world. It’s basic-move/exercise or you WILL get sick. Later maybe-but you will.
The thing about sedentary but healthy people is SUCH an important message to get out there.
Very big thanks to Simon and Inigo for the podcast and making your work and research available in this way. Such important messages that have the power to improve people's lives immeasurably. Thank you
Thank you Simon, A great pod cast. One question I have is are the mitochondrial benefits from zone 2 training body wide or isolated, or concentrated only in those muscles that dominate the exercise?
Great podcast, you’ve had a lot of awesome guests recently. Dr Fuhrman was super interesting!
Keep doing what your doing

Yet another excellent episode, TY.
As a TOFI T2D, I'd rather stay in Zone 1 until and unless the visceral fat completely dissolves, and only then upgrade to Zone 2 because for a hyperlipidemic state like diabetes, that level would most probably be too much of a mitochondrial strain and inevitably induce considerable lactate production...
@@TheProofWithSimonHill I'll keep it in mind. TY
Question: [Literally anything]
Inigo San Millan: "Wow, that's a really great question!"
That is an amazing interview with very clear and linear questions asked to understand the iceberg of zone 2 and its importance before jumping to its applications prematurely.
Thanks a lot Simon and Inigo.
