How 39 compares

This is below average for most adults under 50 — the good news is that the biggest health gains come from moving up from here. Elite endurance athletes typically test at 70–85+ (men) and 60–75+ (women) — see VO2max of elite athletes.

How to raise it

Consistent aerobic volume plus one or two interval sessions a week usually adds several points within a few months: 12-week plan · VO2max workouts · 4×4 intervals.
