WHOOP claims biceps placement rivals wrist-worn heart rate accuracy in swimming and hard efforts, but won’t name the wearables it tested against. For people with wrist discomfort it’s worth tracking, but undisclosed benchmarks don’t prove competitive parity.

Marty’s Take:

Biceps placement finally clearing the accuracy bar in swimming and intervals is the real story: WHOOP is normalizing strap-free wearables, not just fixing a sensor quirk. Watch for Garmin and Polar to follow with their own upper-arm modes within a year. Shoppers chasing wrist comfort should check our best fitness tracker picks before assuming wrist is the only reliable spot.
