Patent-Pending Technology

Engineered for Precision

At the core of PVO₂ is patent-pending technology designed to capture breath-by-breath metabolic data with exceptional accuracy. Advanced sensors are synchronized to each breath, delivering the insights athletes and coaches need to train with confidence and clarity.

Our sensors are advanced, non-depleting and have minimal drift, which eliminates the requirement burdensome calibration and expensive yearly replacement.

Built on Real Physiology

Most training platforms rely on indirect metrics like heart rate or pace. PeakVO₂ 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.

PeakVO₂ 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
