Wearable Recovery Score

A wearable recovery score compresses sleep duration and stages, HRV, resting heart rate, and sometimes prior-day strain into one daily readiness number. Vendors weight those inputs differently, so the same night can score 62 on one device and 80 on another—the number is a model, not a measurement.

Use it for trends: a week of falling scores alongside poor mood and heavy legs is a real signal, while one bad morning after a hard leg day is noise. Cross-check against how you actually feel before changing a session.
