VO2 max is having a moment—and with popularity comes misinformation. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the most common myths and misconceptions around VO2 max, why "more breath" usually isn't the problem, and how performance depends on far more than one number. They cover what's actually trainable, why wearables can mislead, how fat burning and VO2 max don't always move together, and why the best program isn't the most intense—it's the one you can recover from and repeat.
What you will learn Why VO2 max is not "lung capacity," and what typically limits most people
How trainable VO2 max really is—and why "genetics" is often an excuse
Why VO2 max alone doesn't predict who wins (threshold, economy, utilization matter)
Why VO2 max matters for longevity and mortality risk—not just athletes
How Zone 2 and high-intensity work fit together (and why "moderate-hard" stalls progress)
Why higher VO2 max doesn't automatically mean better fat burning
Where wearables help, where they don't, and how to interpret the data responsibly
How metabolic testing can reduce guesswork and improve training decisions
