How to raise VO₂ max
The reliable recipe is high aerobic volume at easy intensity plus one or two hard interval sessions weekly — classic 4×4 minutes at 90–95% of max heart rate with three minutes easy between. Beginners often gain 10–20% in three months.
- • Losing excess body fat raises VO₂ max mathematically since it is expressed per kilogram.
- • Consistency beats intensity — three sessions a week for a year beats six for a month.
- • Retest with the same protocol so the comparison is valid.
FAQ
What is a good VO2 max?
For a 35-year-old man, 43 ml/kg/min is roughly median and above 52 is excellent. For a 35-year-old woman, roughly 36 is median and above 44 is excellent.
How accurate is a VO2 max estimate from a watch?
Consumer wearables typically land within 10–15% of lab values and track trends well, which is what matters for training decisions.
Can VO2 max improve after 50?
Yes. Trainability declines but does not disappear — older adults regularly gain 10–15% with structured aerobic training.
