VO2 Max Calculator

VO2 max is the gold standard measurement for cardiovascular fitness.

What this calculator does

Elite athletes: 70–90 ml/kg/min. Average adults: 30–45 ml/kg/min.

How it works

Improve VO2 max with interval training and consistent cardio.

When to use this calculator

Use this calculator as a starting point for any health or fitness goal that requires a numeric benchmark. The result is an estimate, not a diagnosis — but it provides a concrete figure to track against over time.

Common mistakes

Many users apply adult health classifications to children and teenagers, which is incorrect. Paediatric norms for height, weight, BMI, and body composition are age-and-sex-specific. Use age-appropriate reference tools for anyone under 18.

Real-world scenarios

A personal trainer uses the calculator with a new client to set a measurable starting point. Re-running the calculation at 4-week intervals provides an objective progress metric that supports motivation and programme adjustments.
