What is VO2max anyway and why should I care?

You may have heard of VO₂max, but what does it actually mean?

​

Think of your body like a car. Your muscles are the engine, and oxygen is the fuel. VO₂max tells us how big that engine is—how much oxygen your body can use to produce energy during exercise.

​

The higher your VO₂max, the greater your endurance, the better your cardiovascular fitness, and—most importantly—the better your long-term health. In fact, VO₂max is one of the strongest predictors of longevity that we can measure.​
