Considering the Whoop Strap 3.0 is water resistant, you’re able to keep it on in the shower or for a swim, but it can be a bit uncomfortable when it’s still dripping wet. There is an optional Hydroband strap that’s designed to dry faster. The Whoop Strap 3.0 can also be worn further up your arm, either on your forearm or on your triceps, similar to the Polar OH1+ heart rate monitor. For anyone whose workouts require wrist wraps, like CrossFitters, this is a useful option. There are also optional arm and bicep sleeves, or longer bicep bands
Underneath that unassuming build, there is a lot of activity going on. Every second, the band measures heart rate, heart rate variability (HRV), temperature, motion and whether it is on or off the wrist. This data is synced to the user’s iPhone via Bluetooth (Android compatibility is coming soon) and is used to calculate the three fundamental scores for Whoop: strain, sleep, and recovery
