- Your VO2 max number Often with training zones
A VO2 max test measures how much oxygen your body can use when you are working as hard as you can. You wear a mask and walk, run or cycle while the effort slowly builds. The mask reads the air you breathe in and out, and the highest amount of oxygen your body uses is your VO2 max.
It is one of the clearest ways to measure cardiorespiratory fitness: how well your heart, lungs and muscles work together. Large studies link higher fitness with better long-term health, so many people use the number as a starting point, then train and retest to watch it move. Many clinics also turn the results into heart-rate zones for your own workouts.
