Why it matters

Your body keeps scoreeven when you don't

Most people have no idea how recovered they are, how well they slept, or when they're heading toward injury. These four metrics change that — and elite athletes have used them for years.

HRV — Heart Rate Variability

The millisecond gap between heartbeats reveals your nervous system's readiness. Higher HRV = more recovered, better adapted. Low HRV after a rough night? Your body is telling you to back off before you injure yourself.

Most athletes see HRV rise 15–30% within 60 days of consistent tracking.

Recovery Score

A single 0–100 number each morning that answers: should I push hard today or take it easy? Calibrated to your personal baseline using HRV, resting heart rate, and sleep quality — not someone else's average.

Athletes who train to their recovery score reduce injury risk by up to 40%.

Sleep Quality

Not all sleep is equal. Deep sleep repairs your muscles and immune system; REM consolidates memory and emotion. See exactly how much of each stage you got — and identify the specific habits dragging your score down.

One extra hour of deep sleep improves next-day recovery by an average of 18%.

Strain Score

How hard did your cardiovascular system work today — workouts, stress, commute, and all? Strain (0–21) lets you balance your training load so you push hard enough to grow but not so hard you break down.

Balancing strain to recovery reduces overtraining syndrome risk by 3×.

The best athletes in the world track these metrics daily.

Now you can too — for free, on the watch you already own.
