Hey guys,
I have been using whoop for some time already and got the MG just on release. Initially I wore it as I did with 4.0 on my wrist but I thought I give it a try and see how much better the data gets when I wear it 24/7 on my biceps.
So I got the whoop biceps band and tried.
Unfortunately the results are so much worse than I was hoping for. I believe generally on 24/7 usage and weight lifting the biceps data looks reasonably well but then I did a Intervall running sessions today.
The results are very bad. The sensor is sitting tight in my biceps as it should I guess (comparing to that how to wear whoop on biceps video from whoop on YouTube)
See data below. 1st image is whoop data, 2nd image is my reference data from polar h10 and 3rd image is another Intervall session when I wore the whoop on wrist.
What’s the issue here? Any comments from whoop team?
This will only work for people with smallish arms, but I use the regular strap on my bicep instead of hassling with a bicep band. Both the hydroknit and this band work when I use the device “unfolded” as in the photo.
So, if your arms are on the smaller size, save money.
update: today I did some indoor rowing and exactly the same thing happened with whoop on biceps.
The first 10min or so are looking great but then the HR explodes and is absolutely off.
I had a very consistent HR of approx 120 throughout the session but whoop reports this:
Hi @Jakub87, I asked a member of our Sensor Intelligence team to look into your specific account based on the data you posted earlier. They reviewed your data, and according to our internal flag, the strap appears to have become loose around the same time the heart rate data became less accurate. There was a clear drop in tightness approximately 15 minutes into the activity, which aligns with your decline in HR accuracy. Our advice is to tighten the strap tighter. That should fix the issue. If it continues, feel free to ping Membership Services at support@whoop.com and they can take a look at your strap with you.
Hey @Durkin , thanks for the quick reply and support. Okay I see, I will give this a try tomorrow with tighter band on the biceps and report back if it fixes it.
I hope I won’t need to tighten it so much it becomes uncomfortable for 24/7 wear
@Durkin getting back to you. I tried to put it a bit tighter on the biceps and can in fact confirm, data from the run today looks good again!
Thanks for your support and looking into the data. Helped me to narrow down and fix the issue!
