What Is VO2 Max and How Can You Improve It?
Aerobic capacity is one of the strongest predictors of longevity.
What it measures
VO2 max is the greatest amount of oxygen your body can use during intense exercise. It is expressed in millilitres per kilogram per minute.
Why it matters
Higher VO2 max is linked to lower risk of heart disease and early death. Moving from the lowest fitness group to the next shows some of the biggest benefits.
Improving it
Combine regular easy aerobic sessions with one or two interval workouts weekly, such as four 4-minute hard efforts. Gains are often visible within 8 to 12 weeks.
