I understand that ECG readings mean the MG must be on the wrist but other than that, when and why should you prefer wrist over bicep ? Blood pressure trends maybe but then that’s a sleep only requirement.
Also does changing from one to the other affect the overall readings relevance ?
I am thinking, maybe, wearing on bicep in the day and wrist at night.
Any insight from @WHOOP_Team would be really helpful. Thx.
Yes, wearing your WHOOP on your wrist at night and bicep during the day is a smart and valid setup.
Why wrist at night?
It’s required for ECG readings, AFib detection, and blood pressure trends during sleep—features that need closer contact and a consistent pulse signal from your wrist.
Why bicep during the day?
It’s ideal for workouts or activities with wrist movement. It’s more comfortable, discreet, and can improve accuracy during motion-heavy sessions.
Will switching locations mess with your data?
Nope. WHOOP’s validated to give reliable data from both wrist and bicep—just wear it snug. You might want to eyeball your trends for a few days after switching just to confirm all looks good.
TL;DR: Your plan = solid. Just wear it snugly in both spots.
Whoop chat told me the bicep band would work for blood pressure readings. In fact, the product description for the bicep band (see below) only warns that it does not work for ECG, not blood pressure. What is correct"
“The CoreKnit Bicep band is not ECG capable. Members with Life Memberships and Medical Grade devices will only get ECG readings while wearing the device on their wrist.”
It works just fine for blood pressure readings on the bicep
Just read your comment on wearing the biceps band during the day. I had the impression that steps tracked are then much lower at least with the 4.0 - has this changed with the 5.0 bands?
Whoop is just a strain data point for me. I typically wear a Fenix 8 and an Oura ring (the two are very closely aligned in step tracking)
