Just watched, he wore it both on wrist and on his bicep (with an old whoop strap). For the wrist the heart rate in various exercises was good to very good (correlation above 0.9 in all cases with reference device). On the bicep it was the best or among the best he's ever tested (0.97-1.0 correlation

Only just started my journey, I was drinking every night not a massive amount but 7 days a week it soon adds up. I’ve noticed my sleep is much better. I’ve got a whoop strap and my sleep rating an recovery have both jumped since I’ve cut down on alcohol. Another change is my resting heart rate is lo

Yes yes yes a 1000 times yes. I used to work out from 2000-2130 with the last 45 mins being cardio. I too used to "sleep" normally or so I thought. But since I got a whoop band I realised that my quality of sleep is piss poor. While my H/R goes down to normal from HIIT in 15 mins resting HR at night

2 year whoop user converted to Helio. Whoop is very useful in the beginning for people who are new to trackers and need help making lifestyle changes but once I understood how to manage my HRV, RHR and sleep cycles I felt like I was paying for a load of stuff I didn't need. Hello covers all that I w

FWIW: I wear a Whoop (optical HR monitor) on my upper arm 24/7. I barely notice it. For 98% of my rides, I just use the data from the whoop strap instead of my garmin chest strap. I have compared the 2 of them multiple times by double recording and the whoop is usually 99% in-line with the garmin. A

I'm pleasantly surprised at how similar both were.

The manhattan chart of heart rate is very similar, particularly the peaks and lows.

The heart rate zones use different metrics, but allowing for that (i.e. zone 3 for Garmin is a mix of Zone 1 and 2 for Whoop) they seem to correlate quite well.

As promised in the previous comparison - Three months with WHOOP MG 5.0, Oura 4, Polar365/Loop, Garmin Instinct 3, Helio strap - here’s the follow‑up focused on half‑marathon heart‑rate measurement.

I also incorporated feedback from the last post; this time I included the Polar H10 as a reference

Okay, so ChatGPT, love it, use it all the time, don’t trust it for shit when it comes to TDEE. I am 208, 5’7, and 25, so very similar to you, my BMR is 1816, and my TDEE is 2250-2400 daily. ChatGPT puts me at about 3300-3600. That’s with 6x weight training sessions at about 45-1hr, and a 30-45 minut
