Another great thoughtful review. If Garmin can improve their data presentation in their apps and can make it more actionable, personally, I can't see a place for this device on my wrist given the cost. Although, I don't love going to sleep with my Fenix 7s (even if it is the smallest device of that line) so I do think these minimalist devices have a place. I would love to see companies like Garmin come out with a low-cost, low-profile companion device for sleep tracking only.

[@DesFit]

There are certainly opportunities from other companies to present this data better and also provide more historical feedback. It will be interesting to see how Whoop does in the long term.

[@SD-ko4tz]

I dislike the fact that sport watches show you all kind of things which effects me. It can also be in a negative way. So just wearing and not shwoing all kinds of things is the positive of the whoop for me

[@hotmail6]

I moved from the galaxy watch 3 to whoop and garmin (by accident, had trouble getting whoop initially and they both ended up showing up on the same day). The galaxy watch 3 showed my HR as sitting between 66 to about 77 throughout the day as it's not sampling as frequently, although it appeared to capture cardio workouts with reasonable accuracy. I'm loving these devices the resolution is awesome HRV and spO2 tracking is wicked and as above great in depth review DesFit. Subscribed.

My experience was with Whoop 3.0 and while I find what Whoop is trying to do with analytics and presentation really interesting, I found it overkill for me, and the expense unjustified. I am also an arthritis sufferer, and if I followed Whoop's strain recommendation following good sleep recovery consistently, my joint health would suffer severely. I certainly dialed back to what I knew my body could sustain, but the analytics called me out as an underperforming slacker. 😆As for the form factor, I found the wristband didn't hold up for me and the device itself caused a skin rash, something no sports watch has ever done. Perhaps that's been improved in this new version. It will be interesting to see how it all progresses into the future. Nice review Des, thanks!

It's an amazing device in terms of sleep tracking, that being said the really important feature that isn't there is being able to observe all the data during the current time when you're actually doing something, unless you're actually looking at your phone, which isn't really that doable in many activities. so the sleep tracker is useful af, other things lack in accuracy and are not actually visible at the point of time you're doing something.

[@JeremyBarbell]

I found it to be extremely unreliable when it came to sleep accuracy. I had to go back and edit my sleep time almost every single day.

[@askeladd709]

Another thing to keep in mind is health insurance subsidies for health wearables. I'm getting reimbursed $150, and ended up paying $265 for the 12 month subscription, making the $22 a month turn into a very reasonable $9 a month for 1 year. The subscription model works well with that kind of yearly reimbursement, versus the purchase of a $750 watch and only getting the single $150 reimbursement. As long as it's comparable to the fitbit, that's good with me.

i did a serious dive and compared a whoop 3 for 18 months, against Garmin instinct solar, oura ring and apple watch. i kept the apple watch because insurance paid and it seemed more accurate than all the others. i liked the body battery with garmin but it seemed to me that the oura ring was better with recovery info and sleep. garmin was more hit and miss even though i loved the instinct in general. oura was much more consistent for sleep than the others. whoop just seemed to miss with heart rate and that messed with hrv/recovery. i decided against trying whoop 4. oura and apple are plenty.

[@craigclark5845]

Good review, I have had my whoop 4 for a week now, I love how light it is. I find the heart rate as accurate or the same as my Apple Watch series 6 when worn on the wrist. I really like it so far, I also have that battery issue, where you need to slide it off and back on again to charge. I am sure this could be fixed with a firmware update, I did update the battery pack firmware and the watch firmware. It is expensive and I also dislike subscription services, but so far I’m happy with the device.

[@louisschmidt1421]

A fitbit inspire is smaller and lighter. Offers similar metrics, has a display. Cost 70Euro for the device and 12 month premium. The app is a little bit to coloured and not intuitiv. But this wasn’t whoop as well. Both are not good which deep sleep detection. That’s why I finally switched to Vivomove sports, which also looks like a normal watch. Using the fitbit at night for hrv and sending back the whoop.

Out of curiosity and since it was worth a Desfit review spot, I casually checked the pricing of this piece of tech. Are they nuts? Anyone who is not depending on optimal performance and the features, feedback- app stuff, AND community is likely to be repelled by the price tag. Suddenly my Fenix 7 seems a much cheaper investment with ongoing development, body battery, and an actual frigging smartwatch with a screen on my wrist. Not to mention the better wrist HR, which is the base for all the fancy calculations...

[@michaelrankins717]

I tried WHOOP and it did not work for me. It would randomly say my heart was racing at 215+ while standing still or walking to my car. I would compare the data with the data from my Fenix 5 to ensure I wasn’t dying and my Fenix was reading heart rate 78ish. This happened almost every other week. I let WHOOP know and I was told the shape of my wrist would make it impossible to be able to use the WHOOP. Hmmm.. OK 👌🏾. I sent the band back. Got an Apple Watch series 7 and have not had an issue with heart rate readings.

[@joshuanicholson420]

Thank for the wonderful in-depth review. This far exceeds what I’ve been researching for awhile. Love hearing the shortfalls too so it gives me some realistic expectations. I am bummed about the fairly expensive subscription too. For everything, I might be okay with something creeping towards USD $12 -15/mth. Maybe there could be tiered level of service with $2 for each component in the future. All things considered there is one thing that’s moving me towards using this. I prefer to not use a tracker on my wrist but rather have it higher on the forearm or even on my bicep. Forearm cos it doesn’t get in the way when I’m working with my hands generally. Bicep so I can have it hidden under my sleeve for whatever occasion. I feel sensors need to stop trying to be a watch and just be what they’re meant to be, sensors.

I love the fact that I can wear a whoop on my wrist with a skin colored strap and no one can tell I'm wearing anything from a distance. Leaves my dominant wrist free for a nice watch. I hate from other products that for me to get any tracking AT ALL I have to wear some gaudy type of sports watch or slim screen watch replacement that really takes the place of a regular watch. In other words, you can't be into nice watches and be into fitness at the same time. Whoop gets my money because I can still wear any watch I want and not look like douche wearing a mechanical watch on one wrist and digital sports fitness tracker on the other.

[@Stefanialak]

I’ve been on a whoop trial for almost a month and I’ve had a similar experience with recovery and sleep performance. I was really surprised on a morning where I didn’t sleep very well to find that my recovery was at 93%. That just didn’t seem right. Still on the fence about whether this is worth paying for. Appreciate the review!

[@michaelpadilla141]

The price + inability to connect to a much more accurate chest strap for HR measurement was the reason I cancelled my Whoop subscription after trying it out for a few months. Garmin is much better, although the downside there is that the presentation of the data needs to be improved. Nevertheless, Whoop (and Oura) are both massively overpriced for what you're getting, aesthetics and hype aside. I'm now using the Garmin Forerunner 745 with a heart strap and find it great for tracking and assessing my workouts (running, weights, crossfit-like hiit) and sleep.

[@DesFit]

Thanks for sharing your experience. Definitely agree on quite a few points.

[@michaelpadilla141]

@@DesFit Thanks for the comment. I love your reviews...thorough and well produced.

[@michaelpadilla141]

Incidentally, one additional point on Whoop vs Garmin...with Garmin, you have the ability to grow within the same ecosystem to the world of cycling power meters, swimming tracking (underwater HR straps) etc. With Whoop, you're forever stuck where you are and would have to move to a completely new system should your training ever evolve. I got my Garmin Forerunner 745 used, but in mint condition, on EBay for about $250.

[@DesFit]

Another great point you bring up regarding the ecosystem 👍 Thanks!

[@hercegmario8679]

So I have Garmin Fenix 6x Pro and I'm looking for exactly something like whoop. Something to track my sleep (Fenix is uncomfortable to sleep with), give additional health info, status, recovery (that I can compare to Fenix) etc. Just a simple strap not a watch with a screen. I did some research and it also appears in this great review as well that Whoop is something like a Beats By Dre (who knows will know what I meant) so my question is there any alternative to Whoop or that's the best we got?

[@Haider1236]

Can you do an updated review? Quantified scientist has said that whoop have massively upgraded there algorithms for HR?

[@MD_COLO]

I was an early adopter of Whoop. Their previous hardware was crap… heartrate data was useless. The 4.0 iteration is much better, as well as their updated algorithm. However, I still find that they put too much emphasis on HRV. And, considering that HRV can be affected by so many other factors other than workout strain, such as temperature, illness, alcohol consumption, stress, etc., it’s not ideal for short-term tracking of recovery. Likewise, Whoop do not actually track the stages of sleep that well. A few somnologists have evaluated Whoop, and their results were not that good. Whoop could not accurately detect between REM and deep sleep. Whoop also seem to penalize your recovery score more when you don’t sleep well, but underweight recovery when you get great sleep. And, ironically, going back to bed after waking up or taking naps seem to have more weight on recovery than if you had gotten the same amount of sleep in one sleep session. Whoop’s calculation of strain seems arbitrary. I realize that it’s impossible to measure resistance/load of a workout with a wrist-based sensor, but Whoop calling it “strain score” is misleading. Whoop should change the name to “Cardio Strain” since this seems to be the emphasis of the strain algorithm. This is where Whoop falls short. Putting aside whether one trusts the data they collect from the hardware, their strain, sleep and recovery algorithm just aren’t useful for making daily decisions on how much effort I should put into my workouts on a given day. The Whoop data might be better used in understanding long-term trends (weeks and months). In my experience with Whoop, the data they present through their algorithm, which is what you’re paying a premium subscription to use, is unreliable and useless for daily training decision making.

[@DesFit]

Thanks for sharing your experience. I agree with you with many of the points you covered.

[@Scott-zt4iq]

Can you provide the “study” that was done, I’d like to read it and newest and the data integrity issues you purport

[@arsenalzm]

What product would you recommend?

[@MD_COLO]

@@Scott-zt4iq I never said “study”, though I do like that you put it in quotes. I said “reviewed”. The only “study” I’m aware of is from the University of Arizona, which was sponsored by Whoop…. So take what you want from that. But, by in large, Whoop was only 50% - 70% accurate at detecting various stages of sleep. And, ~80% accurate at detecting when one falls asleep. Are those acceptable numbers? Compared to other devices that use heart rate and an accelerometer to detect sleep, I suppose it is. But, is the data reliable? Not just from Whoop, but all sleep trackers and/or fitness trackers in general? Reliable and useful data was the point of my original post. And, as stated in my original post, this is my personal experience using whoop and other fitness trackers, as well as the experience of other Whoop users I’ve heard from. So, is the data whoop records reliable? IMO, it’s acceptable. But the bigger question is whether the information derived from that data is useful. IMO, as I said in my original post, it depends. Using Whoop for daily training decisions is a mixed bag. For the most part, it aligns with self reporting. But, there are plenty of occasions where Whoop and my self reporting are polar opposites. Using Whoop for long term trends where one is looking at performance over weeks and months? This is perhaps where Whoop is useful. Is it worth the $30 a month? Again, IMO, it is not. There are plenty of alternative methods to track ones fitness that are much cheaper and just as reliable. Self reporting is free. How do I feel today? Are my muscles sore? Am I struggling to achieve my targets for my intended workout? Was my heat rate suppressed during max efforts? Am I waking up more than usual at night. Am I moody and impatient. These are all indicators of training stress that I can self report just as reliably as Whoop’s strain scope. And for most people that aren’t at the tip of the spear in their sport, self reporting is perfectly adequate to track performance. If you’re a cyclist or multi-sport athlete, Training Peaks can be as cheap as $10/mo. With a proper heart rate monitor and a power meter I have much better data that is far more useful both in tracking daily training input, as well as understanding long tern trends. In general, I find all fitness trackers a novelty. Most people geek out over the data for a period of time. At some point, most people find that the output derived from fitness trackers (Whoop, Oura, Fitbit, etc) to be trivial. Garmin, and other devices in this category, are useful since they track distance, heart rate, as well as receive input from other devices, like power meters, and then upload that data to be processed for training analysis, such as TP. But, even Garmin’s Body Battery is a novelty that most serious athletes ignore. Again, just one persons opinion.

[@MD_COLO]

​@@arsenalzm I don’t recommend any fitness trackers. See my reply to Scott in this thread. What I recommend depends on a number of factors. What sport? How serious of an athlete are you? What are your goals? What’s your budget? And so on. For serious cycling and multi-sport, get a good GPS tracker… wrist based for running, and bar mount for cycling. Then, if your serious about training, get a power meter. Use Training Peaks to track your activities and fitness, as well as understanding the methodology around training for your specific sport. If you still have more budget, find a good coach.

[@RohitSharma-yr7li]

The accuracy of the whoop band is still problematic - so much so, that I probably will not renew my yearly subscription. I have, however, found an easy hack for precise accuracy, especially while running, which is the least accurate of the three sports I do: swimming, cycling, and running. I place the rubber band designed to be worn over the whoop band while swimming, to any time I work out. And the hr data is almost exactly matching my chest strap. Overall, I don’t feel the price justifies the value here anymore. Thanks for your video.

I understand that you can't quantitatively compare them against smth robust like polar h10 in the case of the HR, but even how you "feel" the suggestions of one are more informative than the other would be useful. I own whoop because it has no screens/etc and the data is presented in an information-dense way. I wish it did something like the body battery for the stress/strain incurred during the day, and gave me access to my data. I wouldn't mind switching to something more accurate once other devices (e.g. garmin) are low profile (no screen, can be worn on the bicep).

Charts are pretty look at, but when heart rates are being measured 10-20% lower consistently (e.g., in weight lifting workouts), it's worrisome. It's clear that there is a design fault due to the inability to adjust to quick heart rate jumps, which then further devalues their whole concept of giving HRV a high score in their algo. HRV is literally dependent on being able to track quick changes in your heart rate, which the product can't do well. All over all -- I think the product has potential and has pretty charts-- but the charts and algo are meaningless when studying them from a scientific point of view.

Excellent video,very well presented, product certainly not worth it for the price. Good honest review.

[@DesFit]

Thank you!

[@emthomas10]

Definitely getting one of these since it’s HSA eligible!

[@bikeinmotion]

10 bucks a month and I might consider it. Also it would be nice if it would be as good as my polar OH1 / verity sense so I could replace it. But since it's not as good as the polar (so I have to keep wearing the polar for good data) and way too expensive it's just not worth it. Make it as expensive as my Trainingpeaks subscription and we're talking :)

[@luismarriot586]

Thanks for the video / review man. Really detailed and thought out. I'm currently rocking a Fitbit Charge 2 (I know, it's shockingly still going). Obviously, I'm looking for a new sports watch and had considered a Whoop until I came across this review. I mostly weight-lift and run 3 - 4 times a week (just a 3k). But due to my crazy work schedule, the sleep factor was attractive. I won't be moving forward with my purchase but if anyone has any suggestions on an investment piece for the next 3 - 5 years would love to hear.

[@djwawa5517]

Fitbit charge 2 is amazing and wish i never switched out of mine 😭

[@xFersureMatt]

I just like the way it looks. I dont care about the fitness features.. i wish i could find a regular band look so slick

[@Mr767267]

Great review. I don't prefer the subscription based model but I guess it works for sport professionals.

[@TheBrendNew]

I don't think I can afford WHOOP, however I really like that it is a stylish band and not a "smart watch". Are there any cheaper alternatives that keep the style and also help with fitness and health?

[@SuperDuperCoopster]

Great review - I fully agree with everything you have said. For me, Whoop is worth it because of the gamification of wellness/fitness in which I can compete with my friends. I look forward to seeing my recovery every morning but I know it has its flaws (hardware, price). What wearable do you personally use and believe in now - Garmin? I am very open to trying new wearables. Thank you!

[@johnofavalon1]

It's a big scam. Make sure you slept at least 7 hours a night. Log your sleep with a simple free sleep app. Drink minimum 8 glasses of water upto 16 glasses of water. Eat nutritious food when you are hungry and stop before you are full. You don't need any gadgets and gimmicks.

[@dankspain]

With all these advanced metrics always keep one thing in mind: Garbage in = garbage out. If the HR readings are not accurate I doubt the metrics are any good.

[@captaincommodore8901]

I think there is a big problem with HRV baseline. If for example you get the device and start off a little sick without noticing it, the baseline the device will calculate is ultimately wrong. Thus the whole recovery score could be quite off.

[@tedportnay4086]

Great review. I was an early whoop adopter - started w 2.0 and then 3.0. Then moved over to the Garmin ecosystem. Would love to have seen a comparison of how sleeping tracking and readiness score (green, yellow, red) compared w Garmin’s sleep score and body battery. Thanks

[@DesFit]

I have some comparison videos in the works. Thanks!

[@johnswiderski1494]

Great video.

[@DesFit]

Thanks!

[@bh9262]

I wish you could track your blood sugar levels with Whoop, or a modified version of Whoop. That would be a nice all-in-one health tracker.

[@lewdude2k8]

No chance at the moment unfortunately as good as it would be. Need CGM or needle probably take years for an accurate reading from a watch for blood sugar. If whoop pull that off in the 5.0 then it will be the biggest selling watch of all time probably even overtaking Apple Watch sales

[@wars1ck]

Thanks a lot for taking the time to make this review, you put a lot of effort into it and it really shows! I did have one question about the subscription I'm not sure if you know, what happens if you subscribe for one month and don't like the watch. Can you just cancel and keep the device? Or do you need to send it back? Thanks!

[@BluntBlowinn]

u can send it back within the 30 days but if you decide to keep it for even one month you have to commit to 12 months with whoop. im just now finding that out 6 months later bc i want to switch. dont do it.

[@riskyraccoon]

I'm fine with the subscription, but 3-4 days of battery life is kind of ridiculous when the Inspire 3 lasts a week

[@oryx-lordy87]

Great video, maybe discuss the customer service of WOOP in great detail as it is poor at best. I actually ordered one on the 23rd November 2022, now is the 13th December 2022 and no delivery to date. In contacting WOOP, nothing but continuous excuses and a total lack of customer care skills in fulfilling a clients order. Their postal service is terrible and they do not keep up to date with the postal strikers in the United Kingdom. Their world wide delivery options are terrible. In my opinion, WOOP is a complete scam of an item and i am about to expose them for such.

[@sg2664]

Amazing review! Could you please comment on what it was like to sleep with it on and in that regard how it compared with the comfort of something like an Oura ring? Thank you!

[@ivananelovic3425]

Hvala!

[@DesFit]

Thank you! 🙏

[@ivananelovic3425]

@@DesFit thank you for the detailed review, really helped me understand the product and decide that in the end, it's not exactly appropriate for me.

[@RC-gd7nt]

I’m getting one for my 47th bday in a few weeks and can’t wait! I guess that’s when you know you’re getting old 😂

[@scottleggejr]

I bought it when my fitbit sense died and there's no real repair support for their flagship devices. Whoop's support for the hw is included in the sub so I am using a whoop for fitness/sleep and a smartwatch for smart watch stuff which I take off when I go maniac mode. I'd like to hear about those who have broken a screen on the garmin and what that repair process looks like.

[@howiehirsch1733]

It seems to me that the Whoop device is functionally more like an Oura ring that’s worn on the wrist rather than a smartwatch. I was wondering how it’s features and accuracy compare with the Oura ring. I’d love to see you compare these two devices.

[@DesFit]

I'll see what I can do when Oura finally releases their new algorithms and functions (hopefully mid this year?) Thanks

[@MrDomestosWC]

Whoop recently had a big whoop on their subscription fees. Why? Because many people cancelled their memberships after their honeymoon period was over. So to attract more customers they decided to drop their subscription fees. You may find out that in 2 yrs or so their subscription will be slammed by half. Businesses must soon realize that subscription models don’t work that well. People who thought the product was for them cancel in a short period. People who loved the product will stay but not many of them. While if you sell a device with one time profit you benefit from one time buyers, continuous product supports and younger generations entering the social age where your business aim. By rule I don’t pay subscriptions unless it’s a constantly improving product like Netflix with new shows every month.

[@jonathanberent3182]

Would be curious what you think of a concept that does something similar, but for the brain / mind - strain, recovery rest.

[@megiMove]

I just got mine. Very disappointed that i can't have it on my right arm where i have tattoos. The sensor doesn't work if you have tattoos. So i have to use my garmin on my right since it has no problem getting a reading. Hope they will fix it in the future

[@frankconte264]

If garmin could come out with a band that can be worn during the night because wearing the fenix series watches at night bug the crap out of me

[@ADVRaiderKTM]

How is it different/better than my Apple Watch 7. It seems that Apple Watch, with a combo of native apps and Strava, allow me to get the same exact metric tracking as Whoop. AW also provides significantly more functionality than Whoop

[@michaelheideman3717]

After six months, I like (not love) my Whoop; however, be careful buying any accessories/clothes. If you need to return/exchange, their customer service is terrible, they are slow (30 days) to refund your money and charge you handling/shipping charges for returns/exchanges.

[@Haider1236]

Amazing video. Could you do a review on the xiamoi S1 active? Would love to see that.

[@tyronesnz]

just want to point out that we shouldnt give kudos for support doing their job while the company falsely advertises the battery life..

[@ludwigrosiclair8203]

I actually like that it just looks like a wrist band because I miss wearing nice watches

[@thewildman4300]

any chance you could compare athletic to whoop? I love the apple watch and have tried both the whoop and athlytic and see that the numbers i get are close enough for me to not want to pay for the whoop.

[@jhupiterz]

Hi! Thanks for the in-depth review! How did you get access to the data in order to plot those graphs comparing several sensors?

[@DesFit]

Via the Strava export/sync. Thanks!

[@thesmartsnake]

Wonderful video! I have whoop for a week now! I have had a Fenix 6x solar for the past 2 years now! I wanted to upgrade to the 7 but said let me try something else. from my 1 week's use of whoop I just think it completes my Garmin in the recovery part! also, HR readings are a 1 beat difference between my F6 and whoop 4.0. I like that whoop detects naps. I like the sleep part of it. Garmin's body battery is good sometimes but I still like the part where whoop tells you to go to sleep at a particular time!

[@HunterGabriel-e9l]

When using the bicep band try placing the sensor on the inside of your arm it might detect better HR maybe overall since the artery is right there

[@David-ic4by]

Very simply, this is for people who train every single day or even more than once a day. If you don’t train every day, the thing is unnecessary. Oh, and on the sleep coaching? Don’t drink caffeine after 3 PM and don’t do screen time in bed. You’re welcome.

[@Wayne_Hodge]

What would be a good competitor to the Whoop? Preferably without a subscription
