  Ep. 68 - Muscle Fiber Types & Training: How to Trigger the Right Adaptations for Your Goals

  Aug 18, 202648 min

  Get A Demo: https://korr.com/contact/video-demo/ Ever wonder what's actually changing in your body when VO2 max stays flat but your performance improves? In this episode, we break down the hidden adaptations happening at the biochemical, cellular, and tissue levels—and why patience with your training matters more than you think. We dive deep into energy systems (phosphocreatine, glycolytic, and oxidative pathways), explore how different muscle fiber types adapt to training stress, and reveal why rest intervals between workouts can completely change your results. Plus, discover why central fatigue, sleep, and nutrition are often the real limiting factors in your performance. You Will Learn: What metabolic changes occur BEFORE you see improvements in VO2 max How the three energy systems work and which training style targets each one Why rest intervals between sets determine whether you build endurance or power The critical role of muscle fiber type adaptations in athletic performance How sleep deprivation can sabotage your training adaptations (even when everything else is perfect) Why your training plateau might actually be a lifestyle factor, not a programming issue The difference between peripheral fatigue and central nervous system fatigue How to individualize training based on your unique physiology and constraints The importance of metabolic testing beyond just VO2 max numbers Practical frameworks for designing training that actually produces results

  Ep. 67 - The 6 Pillars of Health: Reverse Aging Without Extreme Exercise

  Aug 11, 202657 min

  Get A Demo: https://korr.com/contact/video-demo/ Is maintenance really possible, or is it a lie? In this episode, we debunk the myth that doing the same fitness routine forever keeps you healthy. Discover why progressive overload matters more than you think, and how the SAID principle (specific adaptation to imposed demands) explains why your body adapts—or declines—based on the demands you place on it. We explore the six pillars of sustainable health, real-world examples of staying young at 90+, and why metabolic testing is your crystal ball for future fitness. Learn how to design a maintenance program that actually works, prevent the 10% VO2 max decline per decade, and combat muscle loss with actionable strategies. You Will Learn: Why "maintenance" requires continuous progression, not repetition How the SAID principle drives aging and fitness adaptations The six pillars of health and how to optimize each one Real data: VO2 max, muscle mass, and metabolic rate changes with age Why activity levels matter more than genetics for longevity How metabolic testing reveals your fitness future and prevents burnout Practical strategies to stay active across all life stages Why your 93-year-old neighbor stays younger than people half his age

  Ep. 66 - VO2 Max vs VLAMax: The Missing Piece in Your Training Program with Sebastian Weber

  Aug 4, 202657 min

  Follow Sebastian: Get A Demo: https://korr.com/contact/video-demo/ Join hosts Dr. Marc Humbert and Dr. Cameron Garber as we explore advanced metabolic testing, energy systems training, and performance optimization with industry-leading experts. In this episode, we dive deep into energy metabolism with Sebastian Weber, founder of Inside and renowned sports scientist. Discover why your current training zones might be limiting your progress, how lactate testing reveals hidden training insights, and the practical applications that separate elite athletes from everyone else. You Will Learn: Why standardized training zones fail (and what actually works) The difference between VO2 Max and VLAMax — and why both matter How lactate production and clearance determine race strategy Muscle fiber recruitment patterns and why you can't neglect glycolytic power Real case studies: Programming for HyROX athletes, cyclists, and endurance performers The truth about fasted training, periodization, and training variation How metabolic data creates a "crystal ball" into what athletes have been doing Why understanding the mechanism behind training beats following trends Perfect for coaches, athletes, fitness professionals, and anyone serious about optimizing performance through science.

  Ep. 65 - Is VO2 Max Testing Just a Fitness Fad? (The Truth)

  Jul 28, 20261h 6m

  Get A Demo: https://korr.com/contact/video-demo/ Is VO2 max testing the real deal, or is it just another fitness fad riding a social media wave? In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber pull from their "Fitness Fad Decoder" framework 10 practical questions anyone can use to separate real, sustainable science from hype and apply them directly to VO2 max testing, zone training, and cardiopulmonary exercise testing (CPET). They break down why VO2 max is a powerful, well-validated number, but a dangerous one to chase in isolation and what actually determines whether VO2 max testing will help you build lasting fitness or just become this decade's fleeting trend. You Will Learn: The 10-question "Fitness Fad Decoder" framework for evaluating any health or fitness trend Why VO2 max is a great indicator of fitness but not a complete picture of health or longevity The difference between population-based heart rate zones and physiology-based training zones Why chasing a single VO2 max score can actually increase injury and burnout risk How fat oxidation (fat-burn zone) differs from fat loss — and why the two get confused What determines whether high-intensity training like the Norwegian 4x4 is right for you right now How symptom-limited and submaximal testing can safely inform training for nearly any population Why cardiovascular reserve and muscle mass both matter for long-term health, not just VO2 max How to evaluate research claims and identify influencer overclaims around fitness trends Why investing in accurate metabolic testing may be one of the highest-ROI decisions for your health or your practice

  Ep. 63 - Why Your Smartwatch's VO2 Max Is Wrong With Daniel Crumback

  Jul 14, 20261h 10m

  Get A Demo: https://korr.com/contact/video-demo/ Wearables and influencers have made VO2 max a household term but most of what's being said about it is misleading, oversimplified, or flat-out wrong. In this episode, Dr. Marc Humbert sits down with Daniel Crumback Director of International Sales at KORR, certified exercise physiologist, chartered physiotherapist, and strength and conditioning specialist to cut through the noise around VO2 max, zone training, and metabolic testing. Daniel breaks down why devices measuring O2 only can't actually calculate a true VO2 max, why a high VO2 max doesn't mean someone is metabolically healthy, and how misapplied protocols like the Norwegian 4x4 can do more harm than good when they ignore an individual's actual limiters. Using a real case study a high-performing executive whose cardiovascular numbers looked great but whose metabolic health was quietly falling apart Daniel shows why testing without proper analysis is nearly worthless. You Will Learn: Why VO2 max and VO2 peak are not the same thing, and why that distinction matters Why O2-only devices can't truly measure VO2 max (and what gets lost in the algorithm) How to identify which system — cardiovascular, respiratory, or metabolic — is actually limiting performance Why "zone two" and "zone five" training aren't competing philosophies but serve different physiological purposes What near-infrared spectroscopy (NIRS) can and can't tell you about performance Why lactate testing has real limits — and where marketing claims cross into dishonesty How AI-generated fitness advice can sound convincing while being physiologically inaccurate Why testing to the modality (rather than testing to find true limitations) leads to bad programming How proper zoning through metabolic testing can prevent long-term issues like metabolic disease What separates a trustworthy fitness expert from an untrustworthy one (hint: they say "it depends")
