VO2 max is the maximum rate of oxygen your body can use during exercise. Higher values indicate better cardiovascular fitness.

What is a good VO2 max score?

For untrained adults, 35–45 ml/kg/min is average. Fit individuals score 45–55, and elite endurance athletes often exceed 60–70. Values above 60 are considered excellent for men; above 55 for women.

Can I improve my VO2 max?

Yes. High-intensity interval training (HIIT) and consistent aerobic exercise are the most effective ways to increase VO2 max. Significant improvements are often seen within 8–12 weeks of structured training.

About VO₂ Max Estimator

Everything you need to know about this tool and how to get the most out of it.

What is VO₂ Max Estimator?

VO2 Max (maximal oxygen uptake) is the maximum rate at which your body can consume oxygen during intense exercise. It's the gold standard measure of cardiovascular fitness and aerobic endurance capacity.

How VO₂ Max Estimator Works

Choose a test method: the Cooper 12-minute run test (run as far as possible in 12 minutes and enter the distance), or the resting heart rate method (enter your resting heart rate measured first thing in the morning). The calculator applies validated formulas to estimate your VO2 max.

Why Use VO₂ Max Estimator?

VO2 max is one of the strongest predictors of long-term health and longevity. Higher VO2 max is associated with lower risk of cardiovascular disease, diabetes, and all-cause mortality. Tracking it over time shows the effectiveness of your training.
