What VO2max Means
VO2max measures the maximum amount of oxygen your body can use during intense exercise.
Higher VO2max values generally indicate stronger cardiovascular fitness.
Why VO2max Matters
VO2max is often used as a marker of aerobic fitness and endurance performance.
Higher VO2max values are associated with lower cardiovascular risk and improved long-term health.
VO2max and Wearables
Wearables estimate VO2max using heart rate, pace and activity data.
These estimates can help track improvements in fitness over time.
See the VO2max Chart for typical ranges.
Core Understanding
VO2max is a central wearable metric for sleep, recovery, stress and training. A useful guide should not only define it, but also explain how to use it in practice.
What You Can Learn from This Metric
Depending on the situation, this metric can help you:
- balance strain and recovery better
- avoid overinterpreting wearable data
- read trends instead of single values
- make better health decisions
How to Use It in Daily Life
This metric becomes most useful when viewed regularly and in context with other signals:
- sleep
- stress
- training load
- subjective well-being
