Inside a VO₂ Max Test using the COSMED Q-NRG Max at Revolution Fitness

Published: 19 June 2026

Discover how the COSMED Q-NRG Max is transforming metabolic testing and helping individuals better understand their health, fitness, and performance. In this video, filmed at Revolution Fitness in Glen Ellyn, Dr. Greg Castello teams up with Zach from Revolution Physical Therapy to guide viewers through a complete VO₂ max test using the Q-NRG Max.

VO₂ max is one of the most reliable indicators of health, longevity, and aerobic performance. The Q-NRG Max provides accurate, real-time measurements of how the body consumes oxygen and uses different fuel sources (fats or carbohydrates) during exercise. From identifying the ideal Zone 2 heart rate for fat metabolism to pinpointing the higher zones needed for sports performance, the system delivers actionable data that helps athletes, patients, and everyday individuals train smarter.

Beyond metabolic testing, the Lab offers a comprehensive, science-based approach to health: physical therapy, lifestyle medicine, weight-loss support, nutritional counseling, behavioral coaching, and expert exercise physiology.

The Q-NRG Max integrates seamlessly into this multidisciplinary model, providing the precision data needed to drive long-term results.

Watch the video to see how cutting-edge metabolic technology, expert analysis, and personalized coaching come together to empower better health and performance.
