What is VO₂ max, and why it matters
VO₂ max is the maximum amount of oxygen your body can use during intense exercise, measured in millilitres of oxygen per kilogram of body weight per minute.
Your fitness engine
It reflects how efficiently your heart, lungs and muscles deliver and use oxygen, the truest measure of aerobic fitness.
A longevity marker
Research links higher VO₂ max to a dramatically lower risk of all-cause mortality. It's one of the strongest predictors of a long, healthy life.
It can be trained
Unlike your height, VO₂ max responds to training. Zone 2 cardio and interval work can raise it by 15–20% in a few months.
What's a good score?
It depends on age and sex. Use the calculator above, then check the norms table below to see where you land.
VO₂ max norms by age & sex
Standard cardiorespiratory fitness classifications (ml/kg/min). Find your age row, then see which band your score falls into.
| Age | Very Poor | Poor | Fair | Good | Excellent | Superior |
