Understanding VO₂ Max: Your Complete Guide to Cardiovascular Fitness

VO₂ max measures your body’s maximum oxygen consumption during intense exercise and is widely recognized as the gold standard for assessing cardiovascular fitness. In this guide, we break down what VO₂ max is, why it matters, how you can measure and improve it, and how it relates to other important fitness metrics.

What is VO₂ Max?

VO₂ max represents the highest amount of oxygen your body can use during maximal exercise. It is expressed in milliliters per kilogram of body weight per minute (mL/kg/min) and is a key indicator of your cardiorespiratory efficiency. A higher VO₂ max generally reflects better endurance and a greater capacity for physical activity.
