The full breakdown. What it is, why it matters, how to use it.
VO2 max measures the peak rate your body can absorb and use oxygen, in ml/kg/min. It's the gold-standard marker of cardiovascular fitness and one of the strongest predictors of all-cause mortality. Zone 2 work raises the floor; HIIT raises the ceiling.

Question 01
How do I improve VO2 max?
Combine 2–3 Zone 2 sessions per week with 1 HIIT session (e.g. 4×4 minutes hard, 3 minutes easy). Most people add 5–10 points in 12 weeks.
