Ep. 56 - Why Everything You've Been Told About Cardio Is Wrong (According to Science)

Get A Demo: https://korr.com/contact/video-demo/ Is cardio bad for your knees? Does running destroy your joints? Will endurance training make you weak? In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber tackle the most common endurance training myths circulating on social media and break down what the science actually says. They explore why cardio gets such a bad rap, how incorrect dosing — not the activity itself — is responsible for most exercise-related injuries, and why the "cardio vs. strength training" debate is a false choice. The doctors also dig into how VO2 max is a powerful proxy for whole-body health, why your heart actually benefits from endurance training, and how individualized metabolic testing can help you finally exercise smarter, not just harder. You Will Learn: * Why "overuse injury" is actually a misleading term — and what's really happening * How zone training prevents knee pain and accelerates recovery * Why VO2 max is one of the greatest predictors of longevity * The truth about cortisol, inflammation, and what exercise actually does long-term * Why endurance athletes live longer — and what the data says about strength-only athletes * How to dose exercise like a prescription to get results without burning out Follow KORR: Instagram: https://www.instagram.com/korrmedical/ [https://www.instagram.com/korrmedical/] Facebook: https://www.facebook.com/korrmedical/ [https://www.facebook.com/korrmedical/] LinkedIn: https://www.linkedin.com/company/korrmedical [https://www.linkedin.com/company/korrmedical] https://korr.com/ [https://korr.com/] Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674 [https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674] Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4 [https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4] YouTube: https://www.youtube.com/@korrmed/podcasts [https://www.youtube.com/@korrmed/podcasts] YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB [https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB] Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery [https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery]

Ep. 55 - The RMR Test Mistakes Everyone Makes (And How Bad Breathing Ruins Your Metabolic Data)

Get A Demo: https://korr.com/contact/video-demo/ In this episode of Metabolic Mastery, hosts Dr. Marc Humbert and Cameron Garber sit down with Daniel Crumback — KORR's Director of International Sales, certified exercise physiologist, chartered physiotherapist, and certified strength and conditioning coach — for a deep dive into one of the most overlooked data sets in metabolic testing: respiratory values. While most practitioners stop at VO2 max or basic metabolic markers, Daniel reveals how tidal volume, breathing frequency, and lung function norms can expose performance limiters that no one else is talking about. From RMR test quality issues caused by over-breathing, to identifying whether an athlete has a respiratory capacity or capability problem, this episode is packed with clinical insight and real-world testing examples. You Will Learn: * Why most RMR tests produce invalid data — and how breathing pattern is usually the culprit * What normal tidal volume and respiratory frequency look like at rest and across all training zones * How to use the GLI (Global Lung Function Initiative) calculator to establish personalized respiratory norms * How to calculate peak tidal volume as a percentage of predicted FEV1 to identify respiratory limitation * Why VE (minute ventilation) masks serious breathing problems that individual respiratory values reveal * How hyperventilation impairs oxygen delivery, cardiovascular output, core stability, and decision-making * The difference between a respiratory capacity limitation vs. a capability limitation — and why the training response is completely different * How recovery data after an exercise test reveals critical information about breathing patterns * Why you should never remove the mask at the end of a test — and what that post-effort data tells you * Practical strategies for improving test quality and helping clients breathe normally during RMR testing Follow KORR: Instagram: https://www.instagram.com/korrmedical/ [https://www.instagram.com/korrmedical/] Facebook: https://www.facebook.com/korrmedical/ [https://www.facebook.com/korrmedical/] LinkedIn: https://www.linkedin.com/company/korrmedical [https://www.linkedin.com/company/korrmedical] https://korr.com/ [https://korr.com/] Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674 [https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674] Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4 [https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4] YouTube: https://www.youtube.com/@korrmed/podcasts [https://www.youtube.com/@korrmed/podcasts] YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB [https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB] Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery [https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery]

Ep. 54 - Choosing Correct Protocols for Bikes, Treadmills, and Other Equipment

Get A The Protocol Guide: https://korr.com/go/metabolic-testing-protocol-guide/ Ever wonder why a client's VO2 max result seems "off" — or why two tests on the same person produce wildly different numbers? The answer almost always comes down to protocol design. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber walk through a practical, step-by-step algorithm for choosing the right metabolic testing protocol for every type of client — from the completely deconditioned to the elite competitor. You Will Learn: * The single most important principle in metabolic testing: how to "test what you intend to measure" * How to assess a client's fitness history and goals to determine the right testing mode (cycling, treadmill, rowing, hiking, and more) * Why protocol choice directly impacts the accuracy of VO2 max, heart rate zones, and substrate utilization data * A watt-by-watt breakdown of cycling protocol progressions (10W to 30W increments) matched to fitness level and gender * Treadmill protocol design for walkers, joggers, runners, ruckers, and elite athletes — including how to handle the "awkward zone" between walking and jogging * When and how to run a submaximal test safely, and how the CardioCoach extrapolates VO2 max from incomplete efforts * How to adjust protocols on the fly without compromising your data * Why standardizing your decision-making process (not your protocol) is the key to consistent, comparable results across retests * Equipment considerations — why walking pads fall short and what treadmill specs actually matter * How strength training history informs both protocol design and exercise prescription Whether you're just starting out with metabolic testing or looking to tighten up your workflow, this episode gives you a repeatable framework you can apply immediately with any client.

Ep. 53 - Submax vs. Max VO2 Testing: How to Design the Right Protocol for Every Client

Get A Demo: https://korr.com/contact/video-demo/ In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down one of the most commonly misunderstood areas of exercise physiology testing: how to properly design submaximal and maximal VO2 tests. Whether you're working with elite athletes, deconditioned beginners, firefighters, or everyone in between, the best test isn't the hardest one — it's the one designed to measure exactly what you need to know. Marc and Cameron walk through equipment selection, protocol design, test length, and the critical indicators that confirm a true VO2 max has been reached. They also explore why calling it "exercise metabolic testing" rather than "VO2 max testing" opens the door to richer, more actionable clinical data — including fat oxidation, lactate thresholds, energy system analysis, and more. You'll Learn: * Why "test what you intend to measure" should guide every protocol decision * How to choose the right exercise modality (treadmill, cycle, rucksack, and more) based on your client's primary activity * The ideal test length range and how to avoid peripheral fatigue skewing your results * Key indicators of a true VO2 max: VO2 plateau, RER thresholds, RPE, and age-predicted heart rate percentage * The difference between VO2 max and VO2 peak — and why it matters clinically * When submaximal testing is the smarter (and safer) choice * How the Cardio Coach enables extrapolated VO2 max from submaximal data — and its limitations * Pre-participation screening tools like the PAR-Q and how they shape your test design * Why VO2 max alone doesn't tell the whole performance story Follow KORR: Instagram: https://www.instagram.com/korrmedical/ [https://www.instagram.com/korrmedical/] Facebook: https://www.facebook.com/korrmedical/ [https://www.facebook.com/korrmedical/] LinkedIn: https://www.linkedin.com/company/korrmedical [https://www.linkedin.com/company/korrmedical] https://korr.com/ [https://korr.com/] Listen to the Metabolic Mastery Podcast: Apple Podcast: https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674 [https://podcasts.apple.com/us/podcast/metabolic-mastery/id1812972674] Spotify: https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4 [https://open.spotify.com/show/2sgLMFv1Z8DwEz87yUpapI?si=29a177a6c6ca4ed4] YouTube: https://www.youtube.com/@korrmed/podcasts [https://www.youtube.com/@korrmed/podcasts] YouTube Music: https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB [https://music.youtube.com/playlist?list=PLVCRWXBDdFo_S0OeaAsPv8xTnfajTLc75&si=d4wVUA0jqajkbukB] Amazon: https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery [https://music.amazon.com/podcasts/d76834b7-c11a-485f-8010-32b490d49e57/metabolic-mastery]
