I just got a Garmin a few days ago. And I use it mainly for runs. Need to track pace, cadence etc. I only wear it when I run. I know I probably went overboard with that purchase, but for sleep/recovery etc I use the Whoop. Best combo ever.

That is the rechargeable battery pack, typically attached when it is off wrist to recharge for a couple hours. The Whoop itself is integrated with the band/strap and very slim. https://preview.redd.it/p5k2ovy62iff1.png?width=2196&format=png&auto=webp&s=7be112a670ae0907ce0aa102cdb1299f822637d9

I was one of the people who, angry about the way Whoop handled the 5.0/MG launch, rage-quit and switched to an apple watch. Even after the "upgrade fee" issue was resolved for users like me who had a long subscription remaining, I was still mad that upgrading would mean I would lose all the bands I had purchased over the years, in exchange for what seemed to me to be just slightly longer battery life. The whole rollout put a bad taste in my mouth, and I decided to throw my whoop in the drawer and instead just use my apple watch. So I went all-in on an apple watch with bevel. And the apple watch is great! I love it. It's fantastic for outdoor activities - runs, biking, etc - and I love being able to go places without my cell phone and still be reachable. Not to mention, because I use(d) natural cycles, I sleep with my apple watch anyway. I used my apple watch heavily all summer, and figured that bevel was pretty close to the same as whoop for strain and recovery insights, so I really wasn't missing much of anything. Well, after a few months my anger died down and I decided that hey, I've pre-paid for my whoop subscription until fall 2026 anyway, I may as well put it back on and make the most of it. So I did. ........You guys. It's gotten better. The UI has improved, the whoop AI coach is significantly improved and the hormonal insights are \*massively\* improved, to the point where I feel like whoop is potentially the best women's health tracker on the market for fitness-focused people (oura has really leaned into women's health, but I think we can all agree that oura can't hold a candle to whoop for fitness). Comparing bevel to whoop, I mean..... look. Bevel is pretty good. As far as apple watch apps go I think it's the best whoop competitor. But it's just not the same at all. Lol. It's not even bevel's fault - the reality is that your apple watch, taking measurements intermittently when not specifically in a workout, is never going to be able to compare with the 24/7 data from the whoop. No matter how good the algorithm is, you're still making connections between dots that are farther apart. And before people comment that "the whoop HR data is unreliable!!", I can tell you that when I work out with my AWU and my whoop on a bicep band, the HR data is within a hair of each other. So, I'm willing to admit when I'm wrong. The apple watch is a fitness \*tracker\* (and phone extension), the whoop is a dedicated fitness & health \*coach\*. That's the difference. Whoop really does provide something special. I'll be here for the foreseeable future, with my 4.0, and my nicer wristband and my bicep band that fit with it. When my subscription is up, maybe I'll upgrade to the 5.0 and buy \*all new bands\* (still raging about this). Or maybe I won't. Either way though, I am satisfied with the value I'm getting from whoop, and no, I don't think the apple watch is the same. Anyway, thanks for coming to my TED Talk.

I’ve had a garmin, an AWU, an oura and a whoop (mostly not overlapping with each other). AWU is best for outdoor activities requiring gps (for me) and whoop has been the best for general life, hormone, fitness and recovery tracking.

I used it for a whole year, it was fun and useful, It did make me learn about myself and sleep pattern. But then some accuracy issues and the fact wearing 24/7 got to my head. Now I am back to Apple watch for steps counting.

By the time I stopped using it, it was BETA and Whoop 4.0. It wasnt accurate at all, increases while im driving the car. I dont know how it performs now. But lets its assume its perfect, i no longer want to wear something 24/7. I wear apple watch for the specific physical activity/stopwatch/timer, and sometimes its a good accessory for casual fashion.

My own personal data showed different for HR accuracy. Apple Watch Ultra 3, Pixel Watch 4, and even Garmin Forerunner 965 did very well compared to Polar H9 chest strap. The Amazfit Helio Strap was even closer. But, Whoop 4.0 and 5.0 devices are just "all over the place" for HR. I don't have an Oura to compare [https://imgur.com/a/C0eXjXl](https://imgur.com/a/C0eXjXl) These are all walking on a treadmill at 3.0 MPH to try to get an "easy" workout for the devices (so no running, no cycling, etc)

I am from India, used whoop for a year when the 4.0 launched. Post that I have used a Garmin, a coros, a pixel watch, a chest strap and an apple watch as well. Now I am back on whoop. It depends on one's goals actually. The apple watch is good at general tracking. The whole rings system is a good daily motivator and social aspect pushes one to achieve daily/weekly/monthly goals. The strength training part was usually an overestimate, so not much of a use unless a third party app is used. Sleep tracking was a bit hard for me cause of the comfort as well as battery/charging issues. Coros and Garmin were good for running and cardio tracking. The battery life was so good. The sleep and recovery part felt really bad on both. I used it mainly to maintain zone 2 heart beat during my cardio sessions. I returned to whoop because it was the one that actually helped me improve my sleep, my daily intensity and habits. Also the trends and data felt more usable than every other wearable. Its the best if you like optimising things based on data. With whoop 5.0/MG the battery is finally really good, the comfort for sleeping is the still the best. Yes, the tracking is sometimes off during upper body workout days, for which I used a bicep band when I was on 4.0. But, I currently only have the wrist version for the MG, so yeah it sucks sometimes but I guess I am fine. The pace of aging, whoop age, bp etc feel like a gimmick and mostly derived from the trends and data already available previously. I think 5.0 peak is good enough. I wish I could downgrade to peak, but they are not letting me do that. The only upgrade of 5.0/MG over the 4.0 is the battery life imo. Still I find whoop to be the best for my current needs. Its really good with sleep tracking and recovery estimates. Also, the RHR and Vo2max trends help me set goals. Plus it lets me wear my wrist watches.

I have had a 4.0 and now an MG. I have never seen my HR numbers stray much from Garmin.

I broadcast my HR from my Whoop to my Bike+ and it works perfectly. In the past I have also done it with a Garmin strap as well as various watches. It is just a matter of preference.

Just go into the Whoop app and turn on HR broadcasting, then go into the BT settings on the bike, and add it like any other HR sensor. Very easy. It should auto connect every time once you have it configured. Took me all of 30 seconds.

only recently been diagnosed but i wear a Whoop! it’s mainly used in the sports world/athletes but it has such valuable data and it helped me a lot in keeping track of things. Whoop shows; heart rate, resting heart rate, respiratory rate, estimated blood oxygen, heart rate variability and skin temp (from baseline)* it also tracks sleep very thoroughly: all the data shown above* REM, deep sleep, light sleep, time awake and stress during sleep. it also has a stress meter, which can affect your bodies daily recovery. aside from all that, it logs every single activity you do. walk? it’s logged. swim? it’s logged. it’ll calculate the strain for you, and add it to your sleep need. it is meant for 24/7 wear (it is completely waterproof!). it works subscription based, so the device is free (you can even try it for free for a month) but you need the subscription to be able to use your whoop. i’m currently on the Whoop 4.0, haven’t upgraded to the new 5.0 or MG which is supposed to be better and show more data😅
