Outcome
VO₂max
A ceiling metric: useful, but endurance performance is usually limited by durability and pacing.
What to do first
- • Get consistent weekly volume for 6–10 weeks before stacking VO₂max intervals.
- • Use one hard session/week if you’re new to intensity; recover well.
- • Measure progress via repeatable workouts, not one-off tests.
