Work out biological age instantly with clear inputs, formula shown and shareable results.
Expresses cardiorespiratory fitness as an age: the age at which your measured VO2max would be average, given the typical annual decline.
Fitness age
Biological age = chronological age - (measured VO2max - population average at that age) / annual decline in VO2max
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
It is the single best-validated physiological predictor of all-cause mortality, which makes it a defensible basis for a fitness age.
No. Methylation clocks measure something different and are not interchangeable with a fitness-based age.
