Whoop 5.0

Whoop 5.0 (launched alongside the medical-grade Whoop MG) is the biggest jump in the line’s history. Battery goes from roughly four or five days to a marketed 14-plus via an on-wrist charging pack, the band is about 7% smaller, the sensor samples 26 times a second, and it adds FDA-cleared ECG, daily blood-pressure insights, and longevity metrics (Healthspan). For athletes who train by readiness, the coaching depth is still the reason to wear it.

Two things temper it. Reviewers still find heart-rate accuracy short of elite, and it remains subscription-only: the hardware comes with the membership, but there’s no buying your way out of the recurring cost. Screenless with no built-in GPS, it’s a pure recovery instrument, not an all-rounder.
