About VO2 Max
VO2 max represents the maximum amount of oxygen your body can utilize during intense exercise. It’s measured in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min).
This measurement is considered the gold standard for assessing cardiovascular fitness and aerobic endurance. Higher VO2 max values indicate better cardiovascular health and fitness levels.
Fitness Level Classification
| VO2 Max Range | Classification | Fitness Level |
|---|---|---|
| < 30 | Very Poor | Low fitness, high health risk |
| 30-34 | Poor | Below average fitness |
| 35-39 | Fair | Average fitness |
| 40-44 | Good | Above average fitness |
| 45-49 | Very Good | High fitness level |
| 50+ | Excellent | Elite fitness level |
Improving Your VO2 Max
