WHOOP MG/5.0 Bicep Band L/XL Black

I bought this WHOOP Bicep Band specifically to wear my WHOOP while kickboxing. Unfortunately, I am very disappointed.

During movement, and especially during kickboxing, the band constantly twists and shifts on my upper arm. I have tried various ways to wear it properly and securely, but during intense movement, it keeps rotating.

The biggest problem is that this causes the contact with the sensor to become unreliable. During a kickboxing training session of about an hour, my workout was recorded, but absolutely no heart rate data was measured: 0 bpm, 0 calories, and no heart rate zones. Consequently, the band is practically unusable for me precisely during the moment I bought it for.

For a product specifically intended for sports involving a lot of movement and contact, I had expected much more from it. On paper, the Bicep Band sounds ideal for intense sports, but in my experience, it does not stay in place properly during kickboxing.

For normal use on the wrist, my WHOOP works well, but unfortunately, the Bicep Band is not worth the money for my specific needs. That is why I sent it back.

Returned after consultation with Whoop regarding functionality
