In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber sit down with Dr. Asa Andrew, physician, chiropractor, functional medicine expert, and host of the nation’s largest health talk radio show.

Dr. Asa shares his unique journey from professional wrestling to clinical practice—and back again—highlighting how metabolic testing, VO₂ max, and cardiorespiratory fitness have become foundational tools for performance, injury prevention, and long-term health.

From elite athletes and entertainers to everyday patients in their 70s and 80s, this conversation explores why VO₂ max should be treated as a key vital sign, how it predicts longevity more effectively than many traditional metrics, and why most age-related decline is driven by deconditioning—not aging itself.

This episode bridges the gap between healthcare and fitness, showing how actionable metabolic data empowers people to stop guessing, avoid burnout, and take the next right step toward better health—at any age.
