VO2 Max Calculator

Enter your VO2 max, age, and sex to see which fitness category you fall into, and how you compare across the full range. Categories are based on standard published exercise physiology norms, not a specific device or provider's proprietary scale.

CategoryRange (mL/kg/min)

These ranges reflect standard published exercise physiology norms (ACSM/Cooper Institute style research), grouped by age and sex since VO2 max naturally declines with age and differs between men and women. They're a general benchmark, not a medical diagnosis, individual results can vary, and the test method used to estimate your VO2 max (lab test, fitness watch, submaximal test) also affects accuracy.
