Metabolic Mastery

Get A Demo: https://korr.com/contact/video-demo/ In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber are joined by Daniel Crumback (Director of International Sales at Core Medical Technologies, and Director of Strategic Health & Performance) to break down how physiological testing can uncover the real reason someone stalls in fitness, performance, and health. Most people think VO2 max and RMR testing ends with a score and a set of training zones. Daniel makes the case that's just the surface. By analyzing oxygen and carbon dioxide data (not O2 alone), you can differentiate whether a person is primarily limited by cardiovascular capacity, respiratory mechanics, metabolic flexibility, neuromuscular function, or efficiency—and then build training and nutrition prescriptions around the true limiter instead of guessing. The team also walks through practical interpretations: heart rate recovery, VO2 peak vs VO2 max, tidal volume vs breathing frequency, fat/carbohydrate crossover, peak fat oxidation, and "efficiency" markers like VO2 per breath and VO2 pulse. They emphasize why protocol design matters, how bad assumptions (like mis-set warmups or mislabeled "fat max") lead to wrong prescriptions, and why retesting every 8–12 weeks is the difference between "working out" and actually improving physiology. What you will learn How to identify whether a person's primary limiter is cardio, respiratory, metabolic, neuromuscular, or efficiency The difference between VO2 peak vs VO2 max, and why it matters for prescribing training Why O2 + CO2 measurement unlocks a deeper analysis (fat oxidation, crossover, metabolic flexibility) How to interpret heart rate recovery and what it can indicate about stress and cardiovascular fitness What tidal volume vs breathing frequency can reveal about respiratory limitations and hyper/hypoventilation How to use fat/carbohydrate crossover and peak fat oxidation to spot metabolic dysfunction (and training mistakes) Why "zone 2" prescriptions often fail without correct protocol setup and correct interpretation How METs relate to real-world function and why very low METs can signal broader limitations Two powerful efficiency lenses: VO2 pulse (oxygen per heartbeat) and VO2 per breath (oxygen per breath) A practical retesting cadence: why 8–12 weeks after consistent implementation is the sweet spot  Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery  

Get A Demo: https://korr.com/contact/video-demo/ In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber walk through a real-world consultation involving a collegiate runner whose metabolic test results didn't match expectations. What starts as a simple test review turns into a deep exploration of training errors, load vs. capacity, the dangers of chronic overload, and how individualized training can transform performance and longevity. Cameron and Marc break down why athletes—especially collegiate endurance athletes—often fall into cycles of injury, overtraining, and frustration. They discuss how heart rate–based training, metabolic testing, fueling strategies, and better lifestyle assessment can uncover the true causes of plateaued performance. You'll learn how elite runners train (hint: much slower than you think), why most people spend too much time in Zone 3, and what it takes to build a resilient, high-performing athlete. This episode is a masterclass in how to ask the right questions, interpret metabolic data, and design training that keeps athletes in the game rather than sidelined by injury. WHAT YOU WILL LEARN How to interpret metabolic test results in the context of an athlete's training history Why most performance problems are training errors, not equipment errors The difference between overload vs. overuse, and why it matters for injury prevention How chronic life stress, poor sleep, and inadequate fueling disrupt performance Why Zone 2 training is foundational—and why Zone 3 can be the "no-progress zone" How elite athletes use slow training to build world-class performance The importance of heart rate auto-regulation for day-to-day training decisions How metabolic testing improves fueling strategies, resilience, and recovery Why individualized plans outperform group training standards How to design the right test based on the athlete's goals and limitations   Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

Bob shares how failing his first sprint triathlon as a "land athlete" soccer player became the catalyst for a career spent in the trenches with athletes. He walks through the origins of nutrition periodization, the birth of metabolic efficiency testing, and why traditional "just eat more carbs" advice often leads to GI distress, underperformance, and confusion—especially for recreational athletes. You'll hear how metabolic carts, substrate oxidation data, and smart training can transform an athlete from a carb-dependent "sugar burner" into a fat-burning, metabolically efficient machine, all while improving health, longevity, and performance. What You'll Learn Bob's unique path from exercise physiologist to registered dietitian and how that dual background shaped Metabolic Efficiency Training. Why energy systems matter (aerobic vs anaerobic) and how misunderstanding them wrecked Bob's first triathlon—and shaped his entire career. The origin of nutrition periodization and why athletes should eat to train, not train to eat. How GI distress in endurance sports led Bob to develop metabolic efficiency testing and rethink high-carb race fueling. What metabolic efficiency testing actually measures: Fat vs carbohydrate oxidation The metabolic efficiency (crossover) point Calories burned per hour How to turn that data into precise fueling plans Why so many recreational runners and triathletes show up as "pure carb burners" on the metabolic cart—and what to do about it. The difference between elite fueling strategies and what's realistic (and safe) for everyday athletes. How optimizing blood sugar and fat oxidation improves performance and long-term health and longevity. Why Zone 2 training is so uncomfortable mentally, and how heart rate monitors should mostly be used to hold you back, not push you harder. How metabolic efficiency testing can guide calorie and carbohydrate intake per hour instead of guessing from generic "30–90g carbs per hour" charts. The role of metabolic flexibility and how to train your body to use the right fuel at the right time. The power of N=1 experiments and why self-testing (with good equipment) is one of the fastest ways to gain coaching wisdom. Why Bob advocates simple, qualitative nutrition models instead of obsessive calorie and macro counting for most people. The difference between biological hunger, habitual hunger, and emotional hunger, and how each one affects performance and body composition. How often you should feel hungry if your blood sugar and fat oxidation are dialed in. Why Bob waited 10 years to release the 3rd edition of Metabolic Efficiency Training and what's new in it (masters athletes, updated strategies, case studies).

Diane shares how she went from an "on again, off again" athlete stuck in a painful injury–weight gain cycle to a consistent runner logging 6 days a week, 1,000+ miles a year, multiple half marathons, and 22 minutes off her half-marathon time – all while avoiding burnout and major injury. You'll hear how VO₂ testing, low heart-rate (Zone 2) training, and data-driven coaching helped her repair her relationship with exercise, food, and her own identity as an athlete. Whether you're a clinician, coach, or everyday runner who feels like you've "tried everything," this conversation shows how the right data, the right plan, and relentless consistency can completely change what you believe is possible. What You'll Learn How Diane broke a years-long cycle of overtraining, injury, and weight regain Why VO₂ and metabolic testing helped her finally trust that her body wasn't broken What true Zone 2 / low heart-rate training looks and feels like in real life How to use heart rate and symptoms as data, not drama, to guide your training The difference between "just resting" and smart load management that keeps you moving How slow, consistent progress led to 22 minutes off her half marathon and ~1,200 miles/year Practical ways Diane and her husband plan runs into a busy family schedule How shifting from "I'm not an athlete" to "I can do hard things" reshaped her identity and relationships Why focusing on health behaviors first (not the scale) protected her resting metabolic rate How to talk to clients about going three layers deep on their "why" so they're ready to change Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery  

Share KORR's Tips For The Holidays With Your Clients: https://korr.com/go/download-korrs-metabolic-holiday-tips/ The holidays are a delicious time of year… and a dangerous time for your metabolism. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down why most people only gain 1–2 pounds over the holidays—yet end up 30–40 pounds heavier a couple of decades later. They walk you through a practical, science-based game plan: from getting your RMR and VO₂ tested before the season, to "calorie budget Tetris," mindful eating at parties, and building holiday traditions that actually move your body instead of parking you on the couch. Whether you're a health professional coaching clients or just trying not to start over every January, this episode will help you enjoy the food, skip the shame, and protect your long-term metabolic health. What you will learn Why average holiday weight gain is "only" 1–2 pounds—and how that quietly compounds into 30–40 pounds over time How RMR and VO₂ testing give you a personalized "holiday baseline" instead of relying on generic calorie calculators The idea of calorie budget Tetris and why weekly trends matter more than a single "bad" day How to use the scale without shame by weighing consistently and understanding normal daily fluctuations Practical mindful-eating tactics: smaller plates, portioning from the source, not "having to" eat everything, and navigating buffet lines How drinks (eggnog, punch, alcohol, holiday lattes) silently blow up your calorie budget Why culture, environment, and family traditions drive overeating more than "willpower"—and how to redesign them Ways to keep movement in the plan through the holidays, including NEAT, daily activity, and building active family traditions   Get A Demo: https://korr.com/contact/video-demo/   Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery  

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber sit down with Tony Orlando, founder of Dexa Plus and DexaScan.com, to unpack why DEXA scans are becoming one of the top longevity markers. They explore how DEXA goes far beyond a simple "body fat test," revealing bone density, muscle distribution, and visceral fat levels that directly impact long-term health, performance, and fracture risk. Tony explains why waiting until insurance finally covers a scan at age 65 or 70 is often too late, and how early, recurring testing—paired with VO₂ max and RMR—can completely change the trajectory of your health. The conversation also dives into GLP-1 medications, hidden muscle and bone loss, youth osteopenia, and how to choose a provider who doesn't just hand you a report, but actually gives you a plan. What You'll Learn What a DEXA scan actually measures (bone, muscle, and fat) and why it matters Why DEXA is a powerful longevity marker, not just a "fitness gadget" How visceral fat drives heart disease and type 2 diabetes risk The dangers of rapid GLP-1–driven weight loss without preserving muscle Why osteoporosis is a silent disease affecting younger adults than you think The critical bone-building window between ages 8–28 How strength training supports bone density for both men and women Why quarterly DEXA, VO₂ max, and RMR testing can guide long-term progress How to interpret body fat percentages realistically (not bodybuilding fantasies) What to look for in a high-quality DEXA provider and how DexaScan.com helps Get A Demo: https://korr.com/contact/video-demo/   Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

Dr. Marc Humbert and Dr. Cameron Garber break down how your body produces ATP through the ATP-PC, glycolytic, and oxidative systems, why "power" (max rate) and "capacity" (how long) are different, and how CardioCoach metabolic testing (VO₂, VCO₂, fuel use) turns those ideas into precise workouts. We dig into thresholds, "fat max," recovery timelines, the injury trap of single-day spikes, and why frequency → duration → intensity is the safest path—whether you're a lifter, runner, or weekend hockey hero. You'll leave with a practical framework to train what you can actually recover from, build longevity, and still hit top-end performance when it matters. What you'll learn The difference between metabolic power vs mechanical power How ATP-PC, glycolytic, and oxidative systems overlap in real workouts "Power" vs "capacity" (and why both matter for sport and longevity) Recovery timelines for ATP-PC/creatine and why rest intervals matter How metabolic testing (VO₂ max, thresholds, fuel use) personalizes training Using fat max and thresholds to place Zone 2 and HIIT correctly Why frequency → duration → intensity reduces injuries and burnout How to balance high- and low-intensity work (including when 80/20 is wrong) Sport-specific profiles (powerlifter vs marathoner vs field/court athletes) Cardio that doesn't kill your gains (fuel-sparing zones for lifters) Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

Schedule A Demo: https://korr.com/contact/video-demo/ "Zone 2" is everywhere—but are we even talking about the same thing? Dr. Marl Humbert and Dr. Cameron Garber sit down with performance physiologist Daniel Crumback to cut through the noise and reframe training zones around what actually matters: ATP production and substrate use. Instead of leaning on arbitrary percentages of HRmax or VO₂max—or single-point lactate snapshots—they unpack how real-time O₂ and CO₂ data reveals where your metabolism shifts, why inflection points beat "crossover" shortcuts, and how to translate those shifts into smarter prescriptions for everyday athletes, patients, and pros. What you'll learn Why "Zone 2" has multiple definitions—and which one holds up physiologically How to use substrate utilization (fat vs. carb) to define zones 1–3 with confidence The pitfalls of percentage-based zones and lactate-only methods (and when they mislead) How to spot true zone boundaries using trendlines and slope changes in VO₂/VCO₂ Practical coaching takeaways: Zone 1 as real recovery, Zone 5 for mitochondrial density, and how to "train to train" when limitations exist Why respiratory mechanics can be the hidden limiter—and how to address it before piling on intensity How to individualize plans so beginners avoid injury and advanced athletes actually progress If you want zones that match your physiology—not an algorithm's guess—this one's your blueprint.   Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery

https://korr.com/products/vo2-max-testing-system/ In this episode of Metabolic Mastery from KORR Medical Technologies, Dr. Marc Humbert and Dr. Cameron Garber dig into the other side of metabolism: carbon dioxide. Everyone talks about oxygen uptake, but CO₂ is the missing puzzle piece that reveals what fuel you're burning (fat vs. carbs), how efficiently your systems are working, and why your training sometimes stalls—or takes off. From Respiratory Exchange Ratio (RER) to threshold detection and heart-rate zone setting, Marc and Cameron show how adding CO₂ data transforms a simple VO₂ snapshot into a precise training prescription. They also explain how CO₂ helps differentiate cardio, pulmonary, and metabolic limitations—and how those insights guide better programming, fueling, and recovery for both everyday athletes and high performers. What you'll learn Why CO₂ is essential: How measuring CO₂ (not just O₂) turns a fitness snapshot into an actionable plan. RER, decoded: What the 0.70–1.00 range means for fat vs. carb utilization—and how it shifts with intensity.

https://korr.com/products/vo2-max-testing-system/ Hybrid fitness meets metabolic science. In this episode of Metabolic Mastery (by KORR Medical Technologies), Dr. Marc Humbert and Dr. Cameron Garber sit down with legendary performance coach Richard Diaz—the man behind "the Secret Lab," world champions in Spartan and HYROX, and a decades-long career testing everyone from triathletes to NHL players. Richard tells the wild origin story of taking over a closing YMCA, building a VO₂ lab in his garage, and growing purely by word-of-mouth. Then we dive into the good stuff: why hybrid athletes can set records with lower VO₂max, matching training to the actual demands of your sport, gait analysis and bike fitting for free speed, using RMR + VO₂ as your crystal ball, and the mindset piece from his latest book Flow. If you've ever wondered whether testing is "only for elites," Richard will change your mind—fast. Practical, contrarian, and insanely actionable.

Why hybrid athletes thrive with "lower" VO₂ scores and what that means for your own training. The role of gait analysis and bike fitting in unlocking efficiency and reducing the cost of work. How VO₂ and RMR testing act like a crystal ball, revealing past training, current capacity, and future potential. The real difference between aerobic vs. anaerobic demands in sports like triathlon, Spartan racing, and HYROX. Why zone 2 isn't enough—and how to train specifically for your sport's demands. The psychology of performance from Richard's book Flow: overcoming resistance, managing the CNS, and entering the zone. Why testing isn't just for elites—how everyday athletes can benefit just as much from proper assessment.   Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery  

https://korr.com/products/vo2-max-testing-system/ VO₂ max gets all the headlines, but it's only one piece of the story. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the full VO₂ results dashboard: VO₂ max, aerobic and anaerobic thresholds (VT1/VT2), heart-rate zones, heart-rate recovery, and how these metrics connect to cardiometabolic health, mortality risk, and healthspan. You'll also learn why "lactic acid burn" is a myth, how body weight changes can shift VO₂ max, and practical ways to individualize zones beyond generic percentage formulas—using real data from CardioCoach. Who it's for: coaches, clinicians, gym owners, endurance athletes, and anyone who wants to train smarter, live longer, and make VO₂ testing useful outside the lab. You'll learn: What VO₂ max actually measures—and why higher isn't always "better" without context How aerobic vs. anaerobic thresholds (VT1/VT2) mark intensity changes and guide training Why lactate is fuel (not "the burn") and what really drives that burning sensation The case for individualized heart-rate zones vs. one-size-fits-all percentages How heart-rate recovery flags autonomic balance and cardio efficiency (key cutoffs to know) The link between fitness "METs" and reduced all-cause mortality—and what that means for healthspan Practical programming: blending Zone 2 base with Zone 4–5 intensity for maximal adaptation How CardioCoach streamlines testing and makes results coachable and repeatable   Follow KORR: Instagram: https://www.instagram.com/korrmedical/  Facebook: https://www.facebook.com/korrmedical/  LinkedIn: https://www.linkedin.com/company/korrmedical https://korr.com/  Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674  Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4  YouTube: https://www.youtube.com/@korrmed/podcasts  YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB  Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery
