How 43 compares
This is around or above average for many adults, and good to excellent after 50. 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.
