VO2 max is one of the strongest single predictors of long-term health in research, and you can estimate it with a stopwatch and a track.
2 / 6
Pick a method: resting heart rate ratio, 12-minute run or 1-mile walk.
3 / 6
Enter your sex, age and the inputs for that method.
4 / 6
Read your estimated VO2 max in ml/kg/min.
5 / 6
Uth (resting ratio): 15.3 × max HR ÷ resting HR, with max HR from 208 − 0.7 × age.
6 / 6
Field estimates can be off by 10% or more compared with a lab treadmill test.
Estimate your VO2 max from your resting heart rate, a 12-minute run (Cooper) or a 1-mile walk (Rockport), with the formula shown for your numbers.
