Readiness score

A readiness score is a daily index defined by each vendor. Devices like Oura and Garmin made it popular (Garmin's version is branded Training Readiness or Body Battery). Whoop's version is branded Recovery, not Readiness. The score tries to tell you how prepared your body is for physical or mental load. It typically blends your HRV, resting heart rate, body-temperature shift, sleep quality, and recent strain. The algorithms differ by maker and lack peer-reviewed standardization. So treat the values as proprietary, trend-over-time signals, not as clinically validated measures.
