Readiness score

A readiness score is a vendor-defined daily index, popularized by devices like Oura and Garmin (whose analogous metric is branded Training Readiness or Body Battery), that aims to indicate how prepared the body is for physical or cognitive load. Whoop's analogous metric is branded Recovery, not Readiness. It typically blends HRV, resting heart rate, body temperature deviation, sleep quality, and prior strain. Algorithms differ by manufacturer and lack peer-reviewed standardization, so values should be treated as proprietary longitudinal signals rather than clinically validated measures.
