The intelligence layer
Your watch knows.
Now your training does.
Garmin, WHOOP, Apple Watch, Oura — they already measure your sleep, HRV and strain. BOXING OS is the brain that turns those numbers into fight intelligence: one readiness score every morning, and a session that adapts to it. No more guessing whether today is a push day.
Your watch measures
Sleep, HRV, resting heart rate, strain — it already knows how recovered you are.
The OS interprets
Signals become one fight-readiness score, tuned for combat training, not step counts.
Your day adapts
Primed → push. Fatigued → skill work. Wrecked → recovery is the session. Automatically.
Feel it work — live
The readiness brain.
Move this morning's signals and watch today's session change. This is exactly what your watch will feed automatically — until then, a 20-second daily check-in teaches the OS your engine.
