Measure your aerobic fitness and cardiovascular health

What is VO2 Max?

VO2 Max is the maximum amount of oxygen your body can use during intense exercise. It's the gold standard for measuring cardiovascular fitness and endurance capacity. Higher values indicate better aerobic fitness.

Cooper 12-Minute Run Test

Run or walk as far as possible in exactly 12 minutes on a flat surface.

These calculations provide estimates of VO2 Max. For laboratory-accurate measurements, consider professional testing with gas exchange analysis. Consult a physician before starting any intense exercise program.
