    7:30 I am defying the laws! Dont change my mind!

  2. @jp_retrospect on April 16, 2025 at 12:08 pm

    I highly suggest you redo a test like this, but with the Polar H10 with any recommended adjustments to it. I really wanna see if the Polar H10 is more accurate than the wrist watches when it comes to tracking calorie burn, since it’s rated by many reviewers and YouTubers as the absolute best and most accurate HR monitor. I also suggest you give a look at Calibre Biometrics, they are attempting to create a vo2 mask/metabolic cart that is both affordable and portable and claims to come very close to those lab-grade results. If this ends up being the case, those kind of masks will likely become mainstream for accurate calorie-burning measurements.

  3. @SayWhaaaaaaaaaaaaaaaaaaaaaaat on April 16, 2025 at 12:09 pm

    BRAIN BURNS THE MOST CALORIES [if you american than no..cause you have to have brain first], AND THERE IS NO WATCH OR LAB THAT CAN MEASURE HOW MUCH CALORIES BRAIN BURNED.

  4. @Brownie861 on April 16, 2025 at 12:09 pm

    3:26 Your Math is the furthest one of Garmin was closest. with 593kcal to the actual 579kcal

  5. @TannerWilson-tj9fb on April 16, 2025 at 12:10 pm

    Super useful video man thanks!

  6. @vittoriobiondi4855 on April 16, 2025 at 12:10 pm

    Isn’t clear whether your test has been performed with the built-in wearables (garmin, apple etc….) wrist heart rate sensor or always with a chest strap connected to the wearables.

  7. @aposebi8591 on April 16, 2025 at 12:10 pm

    How about a chest strap? For example the ones from polar are they also as inaccurate as the watches?

  8. @ItsMido84 on April 16, 2025 at 12:11 pm

    My god this guys so fine 🤤🫠

  9. @rockinrico6206 on April 16, 2025 at 12:13 pm

    really nice video! thank you!

  10. @fredfrenulum2764 on April 16, 2025 at 12:14 pm

    What matters is results.

  11. @fxaman on April 16, 2025 at 12:16 pm

    I had been using Apple Watch for 8 years, working out daily, but eating according to calories burned. In 8 years I gained 90 pounds. That’s how accurate Apple Watch is. Back at that time I had no idea what I was doing wrong. Nowadays I use Garmin, but I lowered my weight by 20 kg and now the numbers feel accurate (I maintain my weight). Lately I’ve been testing Apple Watch as well. On those I had to lower my weight by 30 kg to get similar numbers. Just reduce your Garmin weight by roughly 22 % or Apple Watch by 30 % and you’re good as an estimate.

  12. @ocdjulian on April 16, 2025 at 12:16 pm

    Yo this is kind of a different question than you probably get lol but is there any shot you know of a way around my Apple Watch not being able to read through Tattoos? Had to turn off Wrist Detection because my watch doesn’t read its on my wrist when its on due to the tattoos. Therefor I lose functions like tracking sleep, fitness stuff etc.

  13. @jadedFk on April 16, 2025 at 12:18 pm

    Great video Bin Laden 🙂

  14. @LiberateThePlanet on April 16, 2025 at 12:18 pm

    Absolute accuracy isn’t important. Anyone expecting a wearable to give accurate readings needs to reset their expectations. My advice is to just use it to understand if you are using more or less over time.

  15. @AnaCorrea-yu3qr on April 16, 2025 at 12:18 pm

    This man is so handsome . 😅 thank you . At least I know now I can trust ate least 50 percent on my Apple Watch

  16. @eliryt1002 on April 16, 2025 at 12:20 pm

    It must be possible, for apple atleast, because they are expensive, that you can feed your watch with that information you get with the medical sports test. So the Apple Watch knows you and don’t take average data. 2-4 times a year going to medical sports test, feed your Apple Watch with that information and bam. Ultimate Apple Watch calorie counting

  17. @Somebody294 on April 16, 2025 at 12:21 pm

    It’s worth noting that the calories burned calculations would be a lot more accurate if the watch(es) were connected to a power meter on a bike. Obviously only applicable if your main sport is cycling. Even if the calculations they use are inaccurate you can always just look at total power spent for the ride and do the math with it.

  18. @dupreymartin1 on April 16, 2025 at 12:22 pm

    Accurate or not you gotta admit at least it puts you in the mind set where you need to move at the least 🫡

  19. @TigerKingpin on April 16, 2025 at 12:22 pm

    Just finished a MTB ride. Apple Watch roughly 700 calories. Whoop 1100+ 🤨

  20. @alabenotman7160 on April 16, 2025 at 12:27 pm

    So in conclusion is the Apple Watch accurate or no ?

  21. @anime130 on April 16, 2025 at 12:30 pm

    I heard you get more accurate numbers if you had your Apple Watch on an arm strap closer to your heart.

  22. @paulorr7 on April 16, 2025 at 12:33 pm

    🇧🇷

  23. @kuenholmstrom4525 on April 16, 2025 at 12:34 pm

    The Apple Watch isn’t that accurate for any sports, the steps and calories make me scratch my head. I would only take it with a pinch of salt

  24. @lakshhminarasimhashubhrave8638 on April 16, 2025 at 12:35 pm

    Based on first test, we actually burn 60% of what Apple Watch shows. So will use this as a correction factor.

  25. @weizhen77 on April 16, 2025 at 12:35 pm

    As an engineer myself, there are things that needs to be accurate, and there are things that deserved to be an approximate. One example is Chinese medicine, everything are in approximation, but still effective.

  26. @rcc7170 on April 16, 2025 at 12:36 pm

    What if we don’t use any workout and go solely off of move calories? Would that always underestimate the true calorie expenditure? Would rather underestimate than over

  27. @arbo3495 on April 16, 2025 at 12:36 pm

    The Woop seems very accurate though

  28. @gonrico on April 16, 2025 at 12:36 pm

    Apple watch was off by avg of 11%

  29. @metalhead2328 on April 16, 2025 at 12:37 pm

    your best calorie tracker is your bathroom scale, that bitch doesnt lie

  30. @kuldeepmohanty3063 on April 16, 2025 at 12:37 pm

    Means this smartwatch are only good enough for picking calls and texting hi’ and bye. Its basically a smartphone on the wrist . For fitness and health we still are going through the old ways . I am ok with normal watches

  31. @asianawe9326 on April 16, 2025 at 12:39 pm

    Feel so sad that I spent money on an apple watch for the purpose of motivation to count calories only for it to be an error overall

  32. @dsosys on April 16, 2025 at 12:40 pm

    What about Samsung watch 2

  33. @trustnoone270 on April 16, 2025 at 12:41 pm

    Okay that explains a lot 🫃🏽

  34. @glansingColt2 on April 16, 2025 at 12:42 pm

    lol i just ordered an apple watch

  35. @susikinzki on April 16, 2025 at 12:47 pm

    Apple Watch
    After talking to a lot of people :
    • adjust height/age/ weight(update regular)!
    • total calories burned =/= active calories burned

  36. @HandleName_CB on April 16, 2025 at 12:48 pm

    Lmao, the whole calorie system itself is pseudoscience. 100% error is not as bad as it sounds. Do you know how the fk the calorie of food is measured? If you do, do you think your stomach is a fking crematorium? Also the fancy equipment that measures your reference of “actual calories” has a typical error rate of 38% and its calculation is based on an over simplified theory. Scientifically, it means nothing.

    Those calories number just give you a very rough idea what you eats and what you do. It is meaningless to do math between them.

  37. @farouqnimer on April 16, 2025 at 12:49 pm

    It 2012 i lost 82.5 lbs without having to use any smart device whatsoever and without reading any calorie labels. The internet has no shortage of people like that. It’s not rocket science and we don’t need any of these electronics. Save the money and buy a real luxury watch like Rolex or Cartier

  38. @sebastian3291 on April 16, 2025 at 12:49 pm

    What Apple Watch version did you use?

    first time i see a taliban youtuber

  42. @KatarinaLee-y4f on April 16, 2025 at 12:56 pm

    This dude said, most people spend hours in the gym every week 😂😂😂

  43. @jujuuthebeastONYT on April 16, 2025 at 12:56 pm

    One thing to keep in mind:
    While the Apple Watch might be inaccurate, it is consistenly inaccurate. So you can still use it as an indicator to see trends.

  44. @SayWhaaaaaaaaaaaaaaaaaaaaaaat on April 16, 2025 at 12:57 pm

    ONLY AMERICANS CARE ABOUT CALORIES….. NORMAL PEOPLE FEEL HOW MUCH THEY EAT.

  45. @97itachiuchiha on April 16, 2025 at 12:58 pm

    Im curious how other products that strap around your chest compare, like myzone for example

  46. @kdilkington on April 16, 2025 at 12:59 pm

    3:37 "most people spend hours in the gym every week". They certainly dont…

  47. @adam_doesthings817 on April 16, 2025 at 12:59 pm

    One of the obvious problems with The straps tracking calories is that they use heart rate, I think it’s better to use distance of a walk or a run because it’s always the same. Going faster only makes you burn the same amount of calories in a shorter amount of time So if I walk a mile I burn about 79 calories because of my weight, if I walk quite fast like a 17 min mile, one of these wearables might notice my heart rate being higher and count it as more than if I walk it very slow like 30 min mile. I’m still saying this with a questioning tone because while I’m not 100% sure that I burn 79 calories a mile I am quite sure that whatever I do burn a mile it doesn’t matter if I walk it in 17 minutes or 30 minutes it will be about the same.

  48. @skurt2752 on April 16, 2025 at 1:00 pm

    Did you post the Apple Watch’s “ total calories burned or the “active calories” because your readings for what you did see high

  49. @tonymanero7428 on April 16, 2025 at 1:03 pm

    I dont use the watch to determine my calorie intake but as a measurement of daily activity. 500 or less is a leisurely day, 1000 is active, 1500+ busy as fuck.
