VO2 Max Calculator (Cooper Test)
Estimate your VO2 max, a measure of aerobic fitness.
A benchmark of aerobic fitness
VO2 max reflects how much oxygen your body can use during hard exercise, and it is one of the best single measures of aerobic fitness. This estimates it from a performance or fitness input, giving a benchmark you can track as your conditioning improves.

Estimates, trends and what it means
A true VO2 max is measured in a lab with specialised equipment; any calculator or wearable gives an estimate from a proxy like a running performance or a submaximal test, which is approximate and can differ from the real value. Its main use for most people is as a trackable benchmark — a rising estimate under a consistent method signals improving aerobic fitness, which matters, since aerobic fitness is strongly linked to long-term health. VO2 max also naturally varies with age, sex and genetics, so comparisons are most meaningful against yourself over time. This is general fitness information; if you are new to intense exercise or have any health condition, consult a doctor before hard training.
