Hello everyone,
Honestly, I think the Whoop is the most inaccurate heart rate tracking device I’ve ever used. I’m a 22-year-old high-performance cyclist, training with a Garmin chest strap. During Zone 2 rides, my HR is consistently between 110–135 bpm.
Other trackers (Garmin, Coros, etc.) show 35–38 bpm while sleeping — perfectly normal for my level of fitness. But Whoop? It shows an average of 47 bpm.
Even worse, while walking it randomly spikes from 90 bpm to 167 bpm in less than a minute. The strap is worn correctly — tight, on my left wrist, about 2 cm above the wrist bone — so the usual excuses don’t apply.
I’ve already replaced the device once and the issue is exactly the same. Honestly, at this point it feels like a joke.
Anyone else experiencing this level of inaccuracy?

Yes! I too cycle a lot and the Whoop MG is awful. On the Bicep it seems better but I will still get crazy high spikes for no reason at all. I have a bunch of posts about this subject. It seems to fall on deaf eats sadly..
one my recent posts. HR is soooooooooo bad still!
Search will show loads of people.
Thnx mate. Is ridiculous…

Like I said it’s better on the Bicep but I do not want to move from wrist to bicep constantly. It is designed for the wrist so should work..
I cycle every day and I run into this exact issue. I did an interval workout today and my Apple Watch was reporting 153bpm while my whoop heart rate was reporting 107bpm and continued to do so for the rest of the workout. My whoop heart rate data pushes to Apple health so I have the luxury of seeing where the split in heart rates between Whoop and Apple Watch were during my workout. See the disparity in the last third of my workout.
Yes, I’m aware that the Whoop band has a lower polling rate than the Apple Watch and a heart rate monitor, but can you guys release an update to give us the option to elect having a higher polling rate to increase heart rate accuracy during workouts? I mean, you guys provide a significant amount of activities to select so it’s obvious you guys had heart rate tracking in mind while performing activities. Yet, your hardware can’t even correctly track heart rate rates during said activity. It’s not even off by 10 to 15 bpm. It’s off by like 50 bpm, which is embarrassingly bad. I understand that the heart rate tracking for this band is supposed to be recovery focused, but you guys also added in components to the app like calculating strain and added in all these options to select an activity like cycling or rowing or running etc. You guys might as well remove the strain calculation component in the app as well as eliminating the option to choose activities because you guys can’t track it correctly in the first place. And if you guys come back and say, “wELl iT wOuLd ReDuCe BaTtErY LiFe.” I don’t care about that. It doesn’t take very long to charge it. If this is something you guys can’t fix through a firmware update, then you guys really need to think long and hard about how you’re going to actually improve the hardware on the next WHOOP band because this quite honestly sucks. My Apple Watch Series 6 is five years old and it tracks heart rate better during workouts than the latest whoop band. Get with the times.

Interesting that you report a lower HR. My experience is the opposite but I do tend to agree that the Hardware/Software is not great with the Whoop 5/MG
Another funny thing that came to mind was that I got my advanced labs clinician report today from the bloodwork I completed a few weeks ago and clinician recommended I to do more zone 4 and zone 5 cardio work on a weekly basis. HOW CAN I DO THAT WHEN THE WHOOP BAND CAN’T ACCURATELY TRACK HEART RATE RATES DURING WORKOUTS? RIDDLE ME THAT WHOOP TEAM.
This is an absolute joke especially when taking into account all the marketing they’ve done during UCI events and the Tour de France. It’s completely misleading. The very issue that it can’t accurately calculate heart rate during exercise bleeds into almost every other facet and feature of this app. This also means that the app CANNOT accurately calculate VO2 max. You guys have no business portraying VO2 max readings on the app. My Apple Watch states my VO2 max is 65, my Garmin bike computer reads 60 (but that number is probably lower because my Garmin bike computer is reading the heart rate data from my WHOOP band), and the WHOOP app states it as 51. It’s almost as if you guys should’ve just simply created just the app and figured out a way to read the vitals data off Apple and Garmin watches.
I’m just going to get the WATCH LINK pod so that my Garmin edge 1050 can read my Apple Watch heart rate in real time.

Get a chest strap for the best accuracy to link to your 1050. I personally use Powr Labs HR Chest Strap with my 1040 and at only $35 well worth the investment.
Good to know. Thanks for the recommendation!
