Built on Real Physiology

Most training platforms rely on indirect metrics like heart rate or pace. Peak VO₂ is different.

We measure your body’s true response to effort—capturing the data that actually drives performance: oxygen consumption, carbon dioxide output, and fuel use.

This is the foundation of smarter training.

Measures more than just exercise metrics

Beyond VO₂—Understand Your Metabolism at Rest

Resting Metabolic Rate (RMR) reveals how much energy your body uses at rest—giving you a clearer picture of your baseline metabolism.

Prediction formulas can be meaningfully inaccurate for individuals; measured RMR gives a more personalized baseline.

Peak VO₂ measures your RMR with precision, helping you understand how your body burns energy throughout the day—not just during exercise.

This insight allows you to:

  • Personalize nutrition strategies

  • Support performance and recovery

  • Track metabolic changes over time

  • Support weight-management and body-composition planning
