VO2 Max Estimator
Estimate aerobic fitness from a 12-minute Cooper run distance or a resting-heart-rate method.
Interactive calculator
Estimate VO2 max from field data
Use either a 12-minute Cooper run distance or a resting heart-rate estimate to approximate aerobic fitness. This is a screening-style estimate, not a lab-measured cardiopulmonary test.

Method
12-minute Cooper run estimate
How to use it
- 01Choose the method that matches the data you have: Cooper run distance or resting heart rate.
- 02Enter the required values and review the estimated VO2 max plus the broad fitness band.
- 03Track changes over time using the same method for more meaningful comparisons.
Result guide
- Different estimation methods can produce different values, so trend tracking works best when the same method is reused.
- VO2 max is a training metric and not a substitute for medical evaluation of chest pain, breathlessness, or exercise intolerance.
- Field-test conditions, pacing, and heart-rate accuracy all affect the estimate.
About this calculator
VO2 max is one of the most searched fitness quality markers because it gives users a compact way to talk about endurance capacity. A practical tool should offer both a field-test path and a lighter estimate path.
This page therefore supports a Cooper test estimate for active users and a resting-heart-rate estimate when a run test is not practical.
Frequently asked questions
Which method is better on this page?
The Cooper test is usually the stronger field estimate when you can perform it safely, while the resting-heart-rate method is a lighter screening approach.
Can I compare my result with someone else's?
Broadly yes, but method differences, training background, and test conditions still matter when interpreting the number.
