Why it matters

A number that makes the long game visible

Workouts pay off over years, which makes them easy to skip today. Body age turns that slow progress into something you can see move.

Cardio fitness matters most, and the rest of your habits nudge it. Keep what works, fix the one thing that doesn’t, and watch the number follow.

FAQ

Body age, answered.

Is body age a medical measure?

No. It is an estimate to show where your habits point, built on published research, not a diagnosis.

Why does body age need a recent VO₂max?

Cardio fitness matters most. Your Apple Watch estimates it on outdoor walks and runs; without a recent one inbeat waits rather than guess.

How do I lower my body age?

Start with the change inbeat suggests. For most people it is more hard workouts, more regular bedtimes or simply more steps.
