Why does VO2 max matter?

VO2 max is one of the strongest predictors of all-cause mortality — stronger than smoking, diabetes, or heart disease as individual risk factors. Improving your VO2 max by even a small amount significantly reduces your risk of premature death.

How can I improve my VO2 max?

Combine Zone 2 training (3-4 sessions/week) with high-intensity intervals (1-2 sessions/week). HIIT protocols like 4x4 minutes at 90-95% max HR with 3-minute recovery are highly effective. Consistency over months matters more than intensity.
