FAQ

What is VO2 max?

VO2 max is the maximum amount of oxygen your body can use during intense exercise, and it's a common measure of cardiovascular fitness.

How does the Cooper test work?

Run as far as you can in exactly 12 minutes, then enter the distance you covered. The Cooper test formula estimates your VO2 max from that distance.

Is this as accurate as a lab test?

No. This is a field-test estimate, not a lab-measured VO2 max. Actual results depend on pacing, terrain, weather and effort, so treat this as a general fitness indicator rather than a medical measurement.
