Shervin! Quality content as usual! I'm stalking the internet for the best deal on a does everything fitness watch. Training for a triathlon and want something to aid in run pacing, hr tracking, switching between sports easily. Looking for value but there's just so many frickin choices. Tell me what to get and why please! Money is not a big deal but I don't like wasting it on stuff I don't need either! I'm subbed ❤
If you did a test while walking that would have been awesome. Walking would give you a good baseline. You really can't mess up tracking walking.
Please also do it with samsung I want to which is better I have series 8 and my friend watch 4 classic which is better
Literally have been trying to find a video that does exactly this! Why aren't there more videos doing this? It's crazy, I was curious which would be more accurate
hopefully this will inspire more videos like this!
On multiple times I’ve been looking for a video on a specific health topic and 5 out of 6 times Shervin did it!
I recommend watching "Quantified Scientist", he tests these regularly
@@Dev-Austin he doesn't test calorie tracker accuracy. I watch him too.
@neuroresilience true, I stand corrected.
The average of the four wearables was actually really close to the actual calories burned.
So…. Wear all??
More wearables the better 😂
the comment I was looking for
This makes sense actually based off the error range of these devices. Additionally, it is probable that if you were to add up all of your workouts from the week and compare actual calories burned to device calories,any of these devices would be pretty close (except Apple Watch which seems to be heavily biased in one direction).
if you’re goal is to lose weight the priority is not to overestimate expenditure. So just take half the number it says you burned! Worst case scenario you get a slight bonus deficit which will help balance the innacurate calorie labels of products. You shouldn’t expect to burn a lot of calories in the gym anyways, calorie management is the main way you lose weight.
I still rely on my Apple Watch, whether close to accurate or not I went from 230lbs in late February and to 148lbs now in September. I’ve been pretty happy with what my watch has been tracking so far
Wow, congratulations on your transformation, I've had a similar transformation and I had lost about 40 pounds, the problem you'll face now is your body will try to get that weight back by making you binge eat, have a high protein diet so you don't feel much hungry and stay this weight until your bodyfat genetic setpoint lowers down to 150lbs
@@Eatsuk33how long does it take until my bodyfat genetic setpoint to lower to the weight I want to maintain?
How so fast? so much?
@@martinblazek1090 I don't really know, but I'll say a year or so after that you'll not crave so many calories
@@Eatsuk33iv had this exact problem.
I proper struggle with it.
just started watching this video, already want to comment thanks for this, it has been a question in my head too for a long time!
I love this dude. Going through all this hassle to provided valuable information.
Keep it up my man, you are doing great!
Thank you!! Means a ton
Thanks needed this info
Thank you for the valuable knowledge!
Fantastic video. Thank you for doing this!
I’m on a cut right now and I use a calories tracker app. But I always leave an extra 300 cals on the table after each week to account for caloric discrepancies in nutrition labels and calorie expenditure 👍
Same here. This Video is great for showing the accurarcy Problems of those watches but they are still Good for us in Terms of pointing in the Right Direction :)
Bro this is a good ass channel. Thank you for these experiments and shared results/data.
Thank you for the video and research! Was looking for this kind of channel!
Thank you!
Love this channel! Very entertaining and informative. Great take away statements! Also, if you do shift work, these wearable calculations particularly the sleep are even more off and unreliable. 🤷♀️
Very interesting video. Quick,short and effective!
No useless talking.
Keep up the good work! 👍🏼
Thank you for everything you go through to provide these tests, I hope you realize how helpful you are :)
i'm honored, it's comments like yours that keep me going
Shervin goes so hard to make sure his videos are rigorous and transparent - he's an absolute G
Amazing video! Exactly what I needed
This video is inspiring, we need more people like you who take tests as share the results with people
You've earned a new sub! Appreciate the work!
I’ve usually always take my calories burned with a grain of salt, I just love tracking workouts in general to see trends in my activity and focus on areas I can improve. I love being able to see my paces on long runs, HR is definitely something I wish was more accurate though without having to buy a chest strap.
Your videos are mind bogglingly good. Every video tops the previous. Hope you keep gaining subscribers you deserve it!
Just trying to get better!
I noticed my garmin epix heart rate measurement would jump all over during workouts…probably due it moving around on my wrist too much or changes in angles doing push ups etc. I synced my Polar H10 chest strap to the watch and after doing that it was perfectly consistent throughout the whole workout. Having consistent heart rate data the whole workout is key for the watch to do it’s calculations correctly.
yes! and height + weight
Now this is the kind of info I find helpful!! Thanks dude!
Glad it was helpful!
This is the kind of stuff we need! Amazing work man.. keep it up! Is there a way to check accuracy of these watches while working out with weights?
Great video. Thank you very much for making it.
Shervin my man, great content as usual. Maybe you could add a URL to the Aim7 article?
You sir, just earned yourself a sub!!! 🙌🏼 Thank you for this!!
Just watched a couple of your videos loved them and subbed
Great vid mate. Would definitely be great to see the same tests with chest straps.
I’m curious if you added your cadence/ step length and heart zones in the devices after going through one of the test to give the devices the best chance to track your runs.
Bro doing good work here. Ig it was great i encountered this video. Thanks for putting so much effort for this video. Genuine appreciations sir👍💪
Great video. Another number that seems to be off is your subscriber count at just under 100K. How can that be, with this quality of content? 😮
I appreciate the effort to go through this 🎉
Good review. Thanks. I use Garmin but I almost never look at the calories 👍🏻
Been watching the channel for a while and rewatching vids, you use the polar chest strap, id like to see you use the polar wearables
Your humor is the best. Subscribed!
I've noticed the difference in calorie algorithms myself, each brand has its own set of values -- Fitbit tends to be on the "low side" (compared to other devices, not a lab) when estimating calories, and a lot of that seems to come from their look-up table where they use the exercise assigned (e.g. Ice Hockey has a different value than Power Walking) to adjust the rate of burn. Garmin skews higher and aligns with things like Wahoo and Polar.
One thing I'm not positive about, but I suspect Fitbit's algorithm might be EXCESS calories you burned over basal metabolic rate, whereas some of the others appear to be cumulative. When you subtract your expected BMR from some of the higher ones, they tend to align with Fitbit.
Best approach? Use this as a "relative" metric. If the watch says you burned +1000 calories above average, you were probably more active than usual .. or operating a jackhammer (tends to throw them off).
This is an astute comment and quite frankly the biggest component to this whole topic that was woefully missing in the video. I’ve been religiously using an Apple Watch since it first came out which was right before graduate school for me and I’ve observed many different things with it and other watches. I’m an exercise physiologist and a dietitian so I have a deeper background with this topic than most and I’ve came to some determinations that this video did as well when discussing it with experts but he missed some things. The equations are either poor, don’t use weight, VO2 max, etc. so they’re not going to be calibrated to each person, that’s a HUGE flaw. Also, these watches sometimes use “active” calories or “total” calories like apple who tells you what the different totals are whereas some do this but give you the “active” calories only which makes it much lower than the total calories. There’s no such thing as “active” calories, that’s dumb and isn’t how things are done with exercise research. We just take some means of measure like oxygen intake/co2 output or heart rate and base our calculations off that and potentially your weight depending upon which variable we’re using. I use ACSM equations and others and just use the watch data to get a decent heart rate average for the duration of my workout and put it in cells of a spreadsheet and have a more accurate equation that uses my body weight, VO2, etc. to get much more precise measurements based upon MY BODY rather than whatever the watch is using to make its calculations. There’s error in all of this but my method uses my bodies variables at least to help better predict it though it’s never going to be as good as gas exchange measurements done in a lab as this video pointed out. Overall I think this video was great, but missed a few of those small things that some people don’t know about these different watches.
I had an experience with a treadmill run where my fitbit read my heartrate as 195-210 for over 15 minutes. I got a runner's high, so I pushed myself a bit, but I felt genuinely amazing after the workout. The heart rate reading and the experience just don't match up at all.
Thank you for spending the money for us to provide important information! Shervin you are the best!
My pleasure!
Thank you for the effort!
Hello from Spain!
Amazing videos!!! Congrats. I saw in workout you have edited a training for KickBoxing. I do Boxing and I struggle how to measure since during sparring i do not use Apple Watch it incase I break it. is there any possibility to track with a band? or that data is not exported into Apple watch? Cheers!! :)
Great video! You answered a question I’ve had for a while. Subscribed!
Great video! Almost 100k subs. Let’s go!
Your videos are consistently amazing. They have the quality of a channel with 10 - 50x the subs. Idk if that’s your goal, but you’re gonna get there if you just keep it up.
That's the plan!
@@ShervinShares And you are growing sooooo fast !!
not me thinking I ran enough to burn off all the chelow kabab i ate last night....keep it up Sherv! Your uploads have been great
On the cycling test did you have a power meter connected to the garmin?
I want to thank you so much for this information. I was using my Apple Watch to figure out how much I burn versus how much I eat to lose weight. I was always frustrated on why I wasn't losing. The answer was that Apple gave me a higher calorie burn rate versus the actual amount. I know people say never eat back your calories... But I love food. So I learned it's best if I take off my watch and focus on calories in. You've got yourself a new subscriber!
I would love to see this with Apple watch and his polar H10 connected to see if this is more accurate? Or ways to maybe improve the accuracy of these devices
@ShervinShares Did you use the active cal burned or total cal burned for your Apple Watch?
Would be great if you could calibrate them to your specifications. I’ve been wearing an Apple Watch for years now, my Health app collects a lot of other data that I put into it. I wonder if that data influences my results or not.
thats really the video, i‘ve been looking for the last years. it‘s even better seeing it from you.
thank you!
Im 1 week trying to find a video like this, finally. In Portuguese is impossible to find!
How does this compare to a HRM chest strap? And how much more accurate are they?
great video.., very curious about this.., I knew that the watches weren’t accurate, but to learn how much B they can vary is good to know
yup very fascinating!
hey, thanks for this video. can you see how accurate calorie counters are at restaurant? Like at Chick-Fil-A!!!!
Calorimeter vs Chick-Fil-A
That's not going to be useful information. Calorimeters account for all of the energy stored as heat in the food, but they don't account for the heat that gets wasted during the act of utilizing the food's energy, ie. the thermic effect of food. Food labels generally use food specific atwater factors that do account for an approximate estimate of the food's thermic effect, which means the calorie count on the food label should be lower than the calorimeter reading. And neither, by the way, account for the fact that the average human only absorbs about 80-90% (as low as 30% or as high as nearly 100%) of the calories they eat, the rest is wasted and excreted in the form of urine and feces--although there is no way to uniformly account for this as calorie absorption varies wildly from person to person based upon genetics (for example, I have celiac disease which causes fat malabsorption), lifestyle differences (incl. avg calorie consumption, physical activity, fluid intake), and the composition of your diet (principally fiber intake and degree of food processing)
Outstanding information. Thank you.
You bet!
I lost 80 lbs in 8 months while wearing an Apple Watch Series 7 & learned quickly that the watch was inaccurate because I weighed myself in the morning & at night. I just now set my calorie goal to be 1,600 & know that I actually burn more like 1,200+ calories which is my true goal anyways. While I know it’s inaccurate, it still keeps me driven to reach that number, which has still made me healthier & more active & to be honest I’m completely ok with. Monitoring my sleep habits at least gives me some kinda data that I can go off of that I know when I had a good night’s sleep versus when I didn’t & has changed my sleeping habits to be better. I wish there were more accurate wearables, but for me it’s helped achieve my goals & live healthier so I can’t complain that much.
Hi. Nice video. Would you please let us know what is the name of the app on Apple Watch at minute 4:48? Thanks.
Are the Apple Watch calories you displayed the “Active Calories” from the workout or “Total Calories”?
It looks like it’s total from this.
exactly. I am curious but I don't see any respond here
I wondered about this too. I only pay attention to my active calories burned and not total calories. Apple Watch will also tell you that for certain workout types, you're going to be estimated to burn calories at the same rate as a walk (which is what climbing workout says which is what I do), so it's fair to say that those type of workouts are totally just estimates.
Would also have been interested to see less cardio comparison and a strength-focused workout.
I’ve always only taken wearable numbers and even calories I track in my lose it app as a rough general estimate and tweak according to results and what I’m seeing in the mirror, scale and how I’m feeling. But my thinking is it’s better to have the general estimate than not at all!
great video. also funny to see how the lab techs still wore smart watches even though they know they are often inaccurate.
I need to find a lab that will push the fitness test further than the work supported one i have now. They only push to 70-80% calculated max HR and use a forecasting line for VO2. The one you used to take lactate while running was neat.
that would be cool!
Awesome vid. Love your content!
I feel Garmin is really good at running numbers, but sounds like there's some work to do with the cycling algorithm. I still wear chest strap for my targeted Zone 2 work (just to be sure). I like to verify the chest strap accuracy on incline treadmill walk. It's usually within a couple of points with the treadmill itself. So I definitely trust the chest strap more than the watch itself.
On a related, but trivial, note about the calorie counts being inaccurate. I'm pretty sure Costco is undercounting how many calories are in a serving of their Organic Greek Yogurt. They say 170g == 100 Calories. But my trends show that not to be the case. Even though it's not exactly scientific, it's cool to have trends over a months or even years and be able to tell things like this.
Wow this is very interesting! Thank you for sharing.
And how accurate the the Garmin epix gen 2 in terms of the calories?
I think it would add to your videos to say explicitly which sensor you are using for each device. E.g., I used the Apple Watch wrist sensor only. Then I paired my Apple Watch with a chest strap made by Polar or Garmin, model X and then got these results. Thanks.
Your videos are very satisfying and interesting ❤️
You’ve quickly become my favorite RUclipsr! PLEASE don’t change your style when you grow, you do so great!
i'm honored, thank you!
@ShervinShares What is the best wearable heart rate monitor to pair with the apple watch? I want to start getting the most accurate results as possible.
Really loved your video ❤❤❤
Awesome work mate!
Sorry if this has been asked/answered- I stopped relying on watch heart rate/calorie counts as I had read that as heart rate increases the level of inaccuracy does dramatically as well- so I use a garmin chest strap HR monitor synced to iPhone/fitiv app…. Were any of your readings from a chest worn? I couldn’t tell if when you mentioned garmin (and one screen showed polar) if they were chest strap HR monitors (I still take all numbers with a grain of salt… but wondering if some of the chest monitors are at least narrowing the margin of error)
subscribed. good stuff!
Hi sherwin, to give you a short background. My 1st fitness tracker was xiaomi mi band 2 then transitioned to apple Watch 6 then upgraded to 8. Now I want to replace it with garmin watch. However, Upon watching your video. It gave me doubts if upgrading to garmin is realy worth it.?
You can still use the watch as a consistent barometer. I.e., at the start of my diet I was eating 2300 calories + whatever apple gave me from my daily workouts. I kept monitoring my weight and found 1900 calories + whatever weight loss my watch gives me is the sweet spot. I’ve lost 13 lbs in 2 months doing that
Exactly! Did the same and went -8kg in about 8 months, but with a couple diet breaks. Now I notice I've stagnated for the last 3-4 weeks so I will just bump the base calories down by 200 (I was on 1800) and that should theoretically start moving the needle again, slowly.
Well damn. Would love to see how off watches are in tracking workout metrics when running, like speed, cadence, heart rate…etc,
Respect, tysm bro..
Son impresionantes tus análisis...Sigue así...Gracias por estos videos!!!
thanks!
Thanks brother, really like these videos.
Glad you like them!
I ran a test on PNOE that was working with Whoop to fine tune calorie burn. I am unsure if Whoop still supports this but for me, the calorie burn had a stronger correlation to other professional tests.
Idk if you read these but I was just wondering this yesterday. Im really curious if the Apple Watch ultra could be more accurate if paired with a chest strap HR monitor. I think it would make a great follow up video!! Thank you for all your videos.
This!! /\
Why no Fitbit, which is probably the most popular fitness tracker?
Aqui é do Brasil, obg pelo vídeo na prática!!
You should’ve done more tests to get the avg. I’d say 10 tests of each would’ve been better to assist the accuracy
epic. however if the measuring device is consistently inaccurate you will end up using it "correctly" right?
Dope as content. Love your work.
Thank you!!
In 4:47 Apple Watch shows some Intensity tracking app. Could you please share the name of the app?
How do you not have 1 mil subs yet, you are quality
it looks like the Whoop is usually under, witch could work to help lose weight. Going by a calorie intake lower would mean you can lose more weight but if your goal isnt to lose weight than it could be bad.
These are great vids Shervin. Thanks for taking the time to make them!
I found that the treadmill and watch are always within 10 calories "burned". So is there any real way of knowing? lol
Great video! Thanks! I wanted this information for ages! 🙌
You said that depending on how you wear the watch depends on how accurate it is but I was wondering how accurate the Apple Watch or other wearables would be with the polar heart rate monitor!
Rob at the Quantified Scientist has a ton of videos where he tests various watches against a Polar heart rate monitor. Apple Watch tends to be more accurate than many of the others for various exercises like weight lifting, cycling and running, but as he points out, this is just on him, and the weight and size and how you position the watches on your wrist are some of the variables to take into account.
yes! you're not the only one - i'll have to test that in future videos
Shervin, just curious, is the reported Apple Watch calories the Active Calories or total calories? Apple Watch reports both when you select a workout type.
he used total and I am not sure if it is good or not. Total should be used when you think about it but on the other hand this can be not that accurate because your resting calories are estimated only. So maybe showing active calories should be a way
awesome video, see tons of people take the apple watch numbers as king but obviously that’s not the case
Don't the test results hinge on how accurately the devices can measure the HR? From what I understand you'd have to use a chest strap and pair it with your watch to get an accurate HR reading. I usually pair my Apple Watch with a chest strap. Would be interesting to see if there is a difference. I couldn't tell from the video whether you tested that as well since that's how you seem to do your workouts.
OMG this is a video that I never know I need so bad. Love this video mannnn
thank you so much!
I have been tracking calories on my Apple ultra for about 8 months and it seems pretty accurate because my weight is changing in line with my goals. I was going for a small deficit and lost a lot of body fat. Now I am trying to lean bulk and if anything I find I need more calories than the Apple Watch says I am burning
Did you actually test what each device predicts for calories if you wear a chest strap to do the heart rate measurements?
Great vid. From my experience the apple watch is accurate in more physical (high hr) activities. If you just select an activity but continue doing nothing it will still count active calories. However it is highly consistent when i go for my daily runs (or consistently inaccurate?)
Did you have the same exact body metrics (body fat %, weight, height, gender) on all the companion apps for each device?
Wish you would have put the Fit bit in as well
Honestly, alls I need is a rough estimate. I don’t need it to be exact. It becomes a problem when you are eating a certain amount of calories BASED on that number. It becomes the differential between a calorie deficit, maintenance, or surplus. And at 100 calories in either direction, over time, you will either lose weight or gain weight if you eat based on the number on the watch.
I was so close to purchasing a FitBit purely for seeing my caloric expenditure. Im staying far away from that stuff now.
