VO₂ Max Estimator
Estimate aerobic capacity from resting heart rate using the Uth–Sørensen–Overgaard–Pedersen equation. Higher VO₂ max is the strongest predictor of longevity.
Formula: VO₂ max ≈ 15 × (Max HR / Resting HR). Max HR estimated as 220 − age. Measure resting HR first thing in the morning before getting up for best accuracy.
