The VO2 Max Calculator will instantly calculate VO2 Max for you if you can input your time to complete a one mile walk (walking as fast as you can) and your heart rate immediately after completing the one mile walk. VO2 Max (Volume Oxygen Max) is a measure of how much oxygen a person can use during difficult exercise. VO2 Max is a commonly used indicator of an individual’s cardiovascular respiratory fitness level. Our VO2 max calculator will give you a very good estimate of your VO2 max using the VO2 Max formula above.

To use the calculator, first you must walk one mile as fast as you can. Upon completion, immediately measure your heart rate and record your completion time (in seconds). Use those numbers in our calculator to find out your VO2 max. Over time, you should see your VO2 max increase as you increase your level of fitness.

Let's be honest - sometimes the best vo2 max calculator is the one that is easy to use and doesn't require us to even know what the vo2 max formula is in the first place! But if you want to know the exact formula for calculating vo2 max then please check out the "Formula" box above.
