VO2 Max Estimator
How to run the Cooper test
- Warm up 10 minutes (easy jog or brisk walk).
- Find a flat measured loop (400m track ideal) or use GPS.
- Cover as much distance as possible in 12 minutes. Pace evenly — most fail by starting too fast.
- Cool down 5 minutes.
- Re-test every 8–12 weeks to track aerobic fitness change.
Why VO2 max matters for longevity
VO2 max — your body's maximum oxygen utilization — is the single best fitness predictor of all-cause mortality. A 2018 JAMA Network Open cohort showed that going from "low" to "high" cardiorespiratory fitness halved 10-year mortality risk, with no upper ceiling on benefit (Mandsager et al.).
Frequently Asked Questions
What is a good VO2 max?
It depends on age and sex, but broadly: for men, ~35–45 ml/kg/min is above average and 50+ is excellent; for women, ~30–38 is above average and 45+ is excellent. What matters most for longevity is moving out of the lowest fitness quartile — that is where the mortality benefit is largest.
How does VO2 max affect longevity?
VO2 max is the single best fitness predictor of all-cause mortality. A 2018 JAMA Network Open cohort found that going from low to high cardiorespiratory fitness roughly halved 10-year mortality risk, with no observed upper ceiling on benefit.
How accurate is the Cooper 12-minute test?
The Cooper test estimates VO2 max from how far you run in 12 minutes. It is a well-validated field estimate — typically within a few ml/kg/min of lab testing — and is most reliable when you pace evenly and run on flat, measured ground.
