    Ep. 60 - What Your Breath Actually Tells Us About Your Body (And Why It Matters)

    Get A Demo: https://korr.com/contact/video-demo/ Have you ever wondered how a device that just measures your breath can tell you how many calories you're burning, what fuel your body is using, and how well your heart, lungs, and muscles are working together? In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the fascinating science behind indirect calorimetry and the CardioCoach — in plain language anyone can understand and explain. You Will Learn: What metabolism actually is — and why it's so much bigger than just weight loss or fat burning How your body's three energy systems (ATP-PCr, glycolytic, and oxidative) work together at every intensity level Why the Krebs cycle and electron transport chain matter for your fitness — explained simply What the Respiratory Exchange Ratio (RER) is and how it reveals whether you're burning fat or carbohydrates How indirect calorimetry calculates calories burned from just your breath — and the foundational science behind it What VO2, VCO2, and VO2 pulse actually mean and what they tell us about your cardiovascular health Why metabolic testing isn't just for elite athletes — and how it can help anyone exercise smarter and live longer 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

    Ep. 59 - Fasted Cardio, Cortisol & Fat Burning — What the Science Actually Says

    Get A Demo: https://korr.com/contact/video-demo/   Are you optimizing your workouts based on short-term signals that may not actually lead to long-term results? In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down one of the most misunderstood concepts in fitness — the difference between what happens in your body during a single workout versus what actually drives lasting adaptation over time. You Will Learn: Why fat oxidation during a workout is NOT the same as fat loss over time The real science behind fasted cardio and train-low strategies — and when they help or hurt Why cortisol and insulin get unfairly demonized, and what they actually do in your body How short-term hormonal spikes (testosterone, IGF-1, cortisol) do or don't predict long-term outcomes like muscle growth Why Zone 2 training drives mitochondrial and cardiovascular adaptation — and how metabolic testing helps you stay in the right zone A practical framework for evaluating health and fitness claims you see on social media Why consistency — not any single workout strategy — is the biggest lever for long-term health 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

    Ep. 58 - Debunking the Metabolism Myth: What's Actually Happening to Your Body After 40

    Get A Demo: https://korr.com/contact/video-demo/   Think your metabolism fell off a cliff the moment you hit your 40s? Think again. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the real science behind aging and metabolism — and why most of what you've been told is a myth. You Will Learn: Why aging isn't the real culprit behind weight gain, injury, and metabolic slowdown — and what actually is How your stage of life (not your age) creates the "perfect storm" that wrecks your health The truth about wear and tear, and why your old injuries probably aren't the reason you're still hurting Why NEAT (non-exercise activity thermogenesis) may matter more than your workouts How to use Zone 2 training and metabolic testing to exercise in a way that actually builds you up instead of breaking you down Why muscle is the organ of longevity — and exactly what happens when you lose it Simple, sustainable strategies to defy aging and actually improve with time 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

    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/  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

    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/  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

    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/  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
