The Basics

What is VO₂ max, and why it matters

VO₂ max is the maximum amount of oxygen your body can use during intense exercise, measured in millilitres of oxygen per kilogram of body weight per minute.

Your fitness engine

It reflects how efficiently your heart, lungs and muscles deliver and use oxygen, the truest measure of aerobic fitness.

A longevity marker

Research links higher VO₂ max to a dramatically lower risk of all-cause mortality. It's one of the strongest predictors of a long, healthy life.

It can be trained

Unlike your height, VO₂ max responds to training. Zone 2 cardio and interval work can raise it by 15–20% in a few months.

What's a good score?

It depends on age and sex. Use the calculator above, then check the norms table below to see where you land.

VO₂ max, answered

How accurate is this calculator?
These formulas (Uth resting-HR, Rockport walk, Cooper run and Daniels VDOT) are well-validated field estimates, typically landing within about 10–15% of a lab VO₂ max test. They're excellent for tracking trends, but a continuous wearable or a metabolic-cart test will always be more precise.
Which method should I use?
If you don't want to exercise, use the Resting Heart Rate method. You just need your age and a resting pulse. If you're fit and have a recent race result, Race Time is the most accurate. The walk and run tests sit in between and only need a stopwatch.
What's a good VO₂ max for my age?
It drops with age and differs by sex. A fit 30-year-old man is often around 45–52, a fit 30-year-old woman around 38–45. Scroll up to the norms table to find the exact band for your age and sex.
How do I improve my VO₂ max?
A mix of low-intensity Zone 2 cardio (long, easy sessions) and short high-intensity intervals is the proven recipe. Consistency matters most, and tracking your trend, like the Hume Band does, keeps you honest.
Does the Hume Band measure VO₂ max directly?
The Band continuously tracks the signals VO₂ max is built on (heart rate, HRV and effort) and turns them into a live Metabolic Capacity score plus recovery, strain and biological-age insights, so you can watch your fitness change without a lab.
