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

KORR Medical Technologies — Tue, 14 Jul 2026 06:00:00 GMT

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")

Ep. 61 - Why Research Alone Can't Save You: Applying Science to YOUR Body (N of 1 Explained)

KORR Medical Technologies — Tue, 30 Jun 2026 13:03:26 GMT

In this episode of Metabolic Mastery, hosts Dr. Marc Humbert and Dr. Cameron Garber tackle one of the most misunderstood challenges in health and fitness: how to take population-based research and actually apply it to the individual in front of you — the "N of 1." With an overwhelming flood of new studies published daily, it's easy to either over-rely on research or dismiss it entirely. Marc and Cameron walk through a practical framework for reading research critically, understanding study design, and using metabolic testing data — including VO2 max and resting metabolic rate — to personalize care and training in the real world.

You Will Learn:

What "N of 1" means and why it matters for your health and training
How to evaluate research quality, including study design, population relevance, and statistical vs. clinical significance
Why your VO2 max or RMR result may look "normal" but still be telling an important story about your individual trajectory
The difference between a research roadmap and a blueprint — and how to stop confusing the two
How Bayesian reasoning can help you update your beliefs without flip-flopping on every new study
Why placebo effect, natural disease history, and confirmation bias can fool even experienced clinicians
How the "evidence-based medicine funnel" works: best available research → clinical expertise → individual goals and constraints
Real examples of how metabolic testing reveals outliers that population averages would completely miss
Why effect size matters just as much as statistical significance when evaluating any intervention
How to run your own mini N of 1 experiments over time using repeat metabolic testing

Ep. 62 - How We Helped a Injured Runner Lose 20 Lbs Without a Weight Loss Program (Real Case Study)

KORR Medical Technologies — Tue, 07 Jul 2026 06:00:00 GMT

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber walk through a real-world case study of a female runner in her 40s one who was stuck in a cycle of injuries, told to stop running, and struggling to lose weight despite years of effort. Using resting metabolic rate (RMR) testing, VO2 max data, and evidence-based exercise prescription, they break down exactly how they designed a program focused on injury prevention and performance, and how weight loss followed naturally as a byproduct.

You Will Learn:

Why telling injured runners to "rest it away" creates a vicious cycle that destroys tissue capacity over time
How RMR data revealed this client preserved muscle mass during 12%+ body weight loss
Why metabolic adaptation causes RMR to drop 5–30% beyond what fat loss alone explains and how to track it
The load vs. capacity framework that allowed this client to run every single day for a year injury-free
How Zone 2 training reduced injury risk while actually improving race paces at age 41
Why adherence not the "optimal" program is the single biggest predictor of weight loss success
How protein intake (1.6g/kg) and resistance training protect fat-free mass during weight loss
The danger of false dichotomies in fitness (HIIT vs. Zone 2, cardio vs. strength) and why both are needed
Why bone stress injuries are usually an under-fueling problem, not an overuse problem
How to use metabolic retesting to iterate your coaching when results aren't going as expected

If your VO2 max or RMR testing isn't dialed in, the data is useless.

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the real reason most metabolic tests fail—and it's not the device.

It's the protocol.

From fasting mistakes and caffeine interference to poor test setup and bad coaching during the test, small variables can completely skew results. And if your data is off, every recommendation you make after that is off too.

This episode walks you through how to standardize your testing, troubleshoot bad results, and ensure you're actually measuring what you think you're measuring.

Because better data = better decisions = better outcomes

You Will Learn

Why standardization is the key to accurate VO2 and RMR testing
The "Big 3" test prep rules: fasted, rested, uncaffeinated
How caffeine, stress, and exercise can skew metabolic results
Why most bad test results are NOT the machine's fault
How to identify false high or low RMR readings
The biggest mistakes people make during VO2 testing
How to choose the right protocol based on the client
Why some people don't hit anaerobic threshold (AT)—and what to do
When to retest vs. trust the data
How to interpret results when they don't match expectations

Obesity is one of the most misunderstood public health crises of our time — and for decades, we've been getting the conversation wrong. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber take a deep, honest look at why blaming individuals for obesity ignores the biological, social, and environmental forces stacked against them.

From the Minnesota Starvation Experiment to walkable European cities, from hunger hormones to hyper-palatable processed foods, Marc and Cameron break down the real science of why our bodies resist weight loss — and what we can actually do about it. They also clarify some of the most commonly confused terms in the fitness world: fat oxidation, fat burn, fat loss, and weight loss — and why mixing them up leads people to the wrong conclusions.

You Will Learn:

Why obesity is a public health issue and an individual challenge — and why the answer is always "both"
The biological mechanisms (hunger hormones, metabolic adaptation) that make weight loss genuinely hard
The critical differences between fat oxidation, fat burn, fat loss, and weight loss
Why lean mass is not the same as muscle — and what "fat-free mass" actually means
How sleep, stress, hormones, and movement are just as important as diet in managing body weight
Why slow, steady weight loss preserves muscle and leads to better long-term outcomes
How GLP-1 medications work as a tool to "put on glasses" and restore food choice clarity
How community design, zoning laws, and food environments shape our health decisions
Why metabolic testing (RMR + VO2 max) is a vital sign that should be part of every annual checkup
How the Cardio Coach helps individualize exercise and nutrition programming for real people

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber sit down with Greg Marshall, founder of Fitcher Marketing, to talk about the part of health business that most clinicians avoid: selling.

Greg breaks down why "getting more leads" is the wrong target (sales are the target), why great selling is really leadership + empathy, and how to use question-based selling to help people move forward without pressure or gimmicks. They also connect it directly to metabolic testing: if VO₂ max is a "vital sign," then marketing these services isn't hype — it's getting the right message to the people who need it.

You'll hear practical frameworks like going three layers deep, addressing the emotion behind objections (warranty, price, "I need to think about it"), and why your best long-term clients are often the "hardest" initial sales.

What you will learn

Why "more leads" doesn't matter if it doesn't convert into revenue
The mindset shift from "selling" to selling to help
How to use question-based selling to let clients persuade themselves
A simple way to neutralize "I need to think about it" without being pushy

Get A Demo: https://korr.com/contact/video-demo/

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the growing push for precision exercise prescription and why standard fitness recommendations often miss the mark for the individual. Using a recent consensus statement from leading exercise science organizations as the foundation, they explore why the industry needs clearer terminology, more consistent intensity definitions, and more personalized ways to prescribe exercise.

They unpack the confusion around terms like ventilatory threshold, lactate threshold, metabolic threshold, and heart rate zones, and explain why population-based recommendations are useful for public health but often fall short when it comes to helping real people improve fitness, avoid plateaus, and reduce injury risk. The conversation also dives into VO2 testing, substrate utilization, strength training intensity, recovery, and why better data leads to better outcomes.

If you have ever wondered why two people can do the "same workout" and get very different results, this episode explains exactly why.

What You Will Learn

Why exercise prescription should be individualized instead of based only on generic guidelines
How inconsistent terminology creates confusion in exercise science and coaching
The difference between public health activity recommendations and performance-based exercise prescription
Why metabolic thresholds matter more than simple percentage-based training methods
How VO2 testing helps create more accurate heart rate zones and training targets
Why some people plateau even when they think they are training in the right zone
How to think about minimum effective dose versus maximal recoverable volume
Why intensity and duration must be balanced carefully to avoid burnout and injury
How resistance training intensity differs from cardiovascular training intensity
Why precision exercise prescription can improve adherence, recovery, and long-term results

Ep. 38 - Calories In, Calories Out: True… But Not That Simple (The Real Physiology of Fat Loss)

KORR Medical Technologies — Tue, 20 Jan 2026 07:01:00 GMT

"Calories in, calories out" is a real principle—but it's not a helpful plan unless you understand what drives each side of the equation. In this episode, Dr. Marc Humbert and Dr. Cameron Garber break down the physiology behind energy balance, why scale weight can be wildly misleading, and why people feel stuck even when they're "doing everything right."

You'll hear how appetite, food processing, stress, sleep, and the modern food environment quietly push calories in—while metabolic adaptation, sedentary lifestyles, and declining NEAT (non-exercise activity thermogenesis) suppress calories out. Then, the conversation shifts to what actually works long-term: building sustainable systems, using exercise to "tune up the machine," and focusing on body composition and metabolic health instead of daily scale fluctuations.

What you will learn

Why calories in vs. calories out is true—and why it still feels like it "doesn't work" in real life
The difference between scale weight vs. fat mass, and why day-to-day weigh-ins can create false conclusions
How macronutrient shifts, sodium, digestion, and water retention can swing the scale fast without changing body fat
The biggest drivers of "calories in": energy density, hyper-palatability, labels/portion variability, absorption, stress, and sleep
Why NEAT is often the hidden lever for fat loss (and why "just exercise more" is rarely the answer)
What metabolic adaptation is, why plateaus happen, and how RMR testing can guide smarter adjustments
How VO₂ testing and heart-rate zones change over time—and why retesting improves results
The real relationship between hormones/menopause/aging and body composition (including fat distribution changes)
Why fitness can outweigh BMI for health risk—and why "losing weight fast" can backfire metabolically
A practical framework to reduce shame: skill gap vs. will gap vs. environment gap

Get A Demo: https://korr.com/contact/video-demo/

"First, do no harm" is supposed to be the starting point for every health professional—but in modern healthcare and fitness, we can unintentionally do harm through fear-based language, incomplete informed consent, and "majoring in the minors" while ignoring the behaviors that move the needle most.

In this episode, Dr. Marc Humbert and Dr. Cameron Garber break down how misinformation and nocebo language can increase pain, reduce confidence, and drive people into fear-avoidance patterns that worsen outcomes over time. They also explain why uncertainty is so stressful for patients, how neutral data can create clarity and alignment, and how better testing and better questions lead to better decisions—without unnecessary restrictions or burnout.

What You Will Learn

What "first, do no harm" means in a modern clinical and coaching context
How fear-based or nocebo language can increase pain and reduce adherence
What informed consent should include (options, tradeoffs, short- vs long-term consequences)
Why pain is not always a sign of damage—and how beliefs can amplify symptoms
How the biopsychosocial model reframes pain, recovery, and long-term resilience
The hidden harm of low-value interventions and "majoring in the minors"
Why bad exercise prescriptions lead to burnout, injury, and dropout
How heart-rate zones get misapplied—and why accurate zones support sustainable progress
Why the most harmful message is convincing people they're fragile

Biomarkers are everywhere in health, fitness, and wearable technology—but more data doesn't always mean better insight. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down what biomarkers actually are, why not all biomarkers are created equal, and how misleading metrics can obscure meaningful health decisions.

The conversation cuts through buzzwords like "cellular fitness," "biological age," and proprietary health scores to explain the difference between measured, calculated, and extrapolated biomarkers. You'll learn why standardized testing conditions matter, how poor data can lead to decision paralysis, and why the best biomarkers don't give answers—they help you ask better questions.

If you've ever wondered whether your health data is actionable or just decoration, this episode provides a clear framework for evaluating biomarkers and using them responsibly to improve real-world health outcomes.

What You'll Learn

What a biomarker actually is—and why definitions matter
The three tiers of biomarkers: measured, calculated, and extrapolated
Why more biomarkers do not automatically mean better insight
How marketing-driven health scores can mislead patients and clinicians
Why VO₂ max is a powerful biomarker—and where its limits are
The importance of standardized testing conditions for repeatable results
How wearables can create anxiety and decision paralysis when misused
Why biomarkers should reduce uncertainty, not add noise
How good data leads to better questions—not instant answers

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

Get A Demo: https://korr.com/contact/video-demo/

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down why metabolic testing is one of the most powerful tools for improving health, fitness, and longevity—regardless of your current fitness level.

From beginners restarting after years away from exercise to advanced athletes stuck in cycles of injury or plateau, this conversation explains why relying on generic programs, social media workouts, or willpower alone often leads to burnout, frustration, and inconsistent results.

The doctors explain why VO2 max, while valuable, tells only part of the story—and how comprehensive metabolic testing reveals how your muscles, heart, lungs, and metabolism actually work together. With the right baseline data, fitness becomes personalized, measurable, and sustainable.

If you're tired of guessing, restarting every January, or following plans that don't fit your body or lifestyle, this episode shows how better data leads to better decisions—and better outcomes.

What You Will Learn

Why motivation alone isn't enough to achieve long-term fitness success
Why VO2 max is important—but not the full picture of health or performance
How metabolic testing creates a personalized fitness and longevity roadmap
Why beginners, intermediates, and elite athletes all benefit from testing
How improper training leads to burnout, injury, and plateaus
Why consistency—not intensity—wins in the long run
How metabolic data helps match training effort to real physiological goals
Why metabolic testing is a baseline you can't "fail"
How testing supports fat loss without sacrificing muscle or metabolic health
Why starting with data prevents the cycle of stop-and-start fitness

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber sit down with Bob Seebohar – registered dietitian, exercise physiologist, founder of the Metabolic Efficiency Training™ concept and Energy Performance, and author of Metabolic Efficiency Training (3rd Edition).

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).

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

Coach Chris Navin—triathlon & marathon coach, 400+ races, 50+ Iron-distance finishes, Team USA qualifier 25+ times—joins Dr. Marc Humbert and Dr. Cameron Garber to unpack how metabolic profiling turns guesswork into PRs. Chris shares his unlikely journey from certified ethical hacker to endurance coach, why most athletes train a little too hard and fuel a little too little, and how VO₂ testing (O₂ and CO₂) lets you individualize zones, nail fueling, avoid injuries, and even negative split your marathon. We dig into "level 1 vs. level 2" testing, long-form testing with CardioCoach™, zone-2 misconceptions, fat-max shifts, and Chris's Four-Star Endurance method (Plan, Test, Learn, Inspire) that helps everyday athletes perform like pros—often improving VO₂ max and race times with age.

What you'll learn

How to read a metabolic profile (fat/carb crossover, thresholds, fat-max) and turn it into training zones

Why running "easier" can make you faster (and lighter) on race day

The difference between level 1 (baseline VO₂ + zones) and level 2 (fueling-focused, event-specific) tests

Evidence-based fueling math for marathons and Iron-distance events (and why most bonk near mile ~18–20)

A simple rule to prevent injuries: don't raise volume and intensity at the same time

How to use devices/apps (Garmin, Connect IQ, Myzone) after you calibrate them with lab data

The Four-Star Endurance framework to keep athletes motivated long-term

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.

Ep. 22 - Why CO2 Matters? Fats Vs Carbs

KORR Medical Technologies — Tue, 30 Sep 2025 06:01:00 GMT

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.
Setting better zones: Using the relationship between heart rate and RER to place truly individualized training zones.
Metabolic flexibility: What it is, why it matters for performance and health, and how to improve it.
Thresholds with precision: How CO₂ sharpens aerobic/anaerobic threshold detection beyond O₂-only methods.
Efficiency & diagnostics: Reading VE/VCO₂ and other patterns to spot cardio, pulmonary, or metabolic inefficiencies.
Fueling that fits: How substrate data guides on-the-run fueling to avoid bonking and gut issues.
The training triangle: Balancing frequency, intensity, and duration so progress is steady—not injury-prone.
Zone 2, done right: Programming volume and recovery to drive fat-adaptation without constant glycogen depletion.
When hardware matters: Why KORR CardioCoach Max/Pro (with CO₂) unlock deeper insights than O₂-only testing.

Ready to make your testing prescriptive, not just descriptive? Tune in and learn how CO₂ data bridges health and performance—so your workouts finally match your goals.

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

KORR Medical Technologies — Tue, 11 Nov 2025 07:01:00 GMT

Get A Demo: https://korr.com/contact/video-demo/

Aerobic vs anaerobic power isn't just sports-science jargon—it's the operating manual for your training and daily life. 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)

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

How many calories did you really burn during your workout?

Your watch says 600. The treadmill says 450. Your app says 700. Who's right?

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down how exercise calories are estimated, why most methods are flawed, and how metabolic testing using indirect calorimetry changes the game.

They explain how resting metabolic rate (RMR), MET values, and predictive equations are used inside software tools, why wearables often overestimate calorie burn, and how VO₂ testing allows clinicians to dial in nutrition and exercise with far greater precision.

Most importantly, they discuss how accurate data helps practitioners move from blaming patients to partnering with them — using physiology instead of assumptions to guide better outcomes.

What You Will Learn

Why exercise calories are always estimates (unless you're in a metabolic chamber)
How RMR and METs are used to calculate calorie burn
Why wearables can be 28–93% inaccurate
The difference between accuracy and precision in tracking data
Why exercise only accounts for ~5% of total daily energy expenditure
The truth about EPOC and post-workout calorie burn
How underfueling leads to RED-S and metabolic downregulation
How VO₂ testing personalizes heart rate zones and fuel usage
Why accurate data allows clinicians to coach with compassion instead of blame
How metabolic testing creates a prescriptive roadmap instead of guesswork

Note: Part of this episode uses charts. Check out the video version to see them in action.

Respiratory limitations are one of the most overlooked performance bottlenecks in exercise physiology, and they can quietly cap results even in highly trained athletes. In this episode, Daniel Crumback breaks down how to identify respiratory limitations using ventilatory patterns you can already see in metabolic testing data—without getting fooled by "good" minute ventilation (VE).

You'll hear why breathing is controlled differently across intensities, why CO₂ clearance becomes the dominant driver in Zone 4–5, and why trying to "force" nasal breathing or slow breathing during testing and training can backfire. Daniel walks through practical interpretation using breathing frequency + tidal volume, explains how to use GLI predicted values to establish norms, and outlines the seven major types of respiratory limitations—so you can stop guessing, stop mislabeling problems as metabolic, and start fixing the true limiter.

What you will learn

Why VE can look "good" even when breathing is inefficient (and why it can fool you)
How to read breathing using tidal volume (VT) + breathing frequency (BF) across zones
The real role of breathing at higher intensities: CO₂ removal and pH control
How to compare Peak VT to predicted FEV1 using GLI norms (and why 75–85% matters)
The 7 respiratory limitation types (capacity, capability, coordination, and more)
When resistive breathing devices help—and when they reinforce the wrong adaptation
How respiratory limits can mask as "metabolic problems" by disrupting O₂ offloading
When poor response to training is a red flag that warrants medical referral

Ep. 40 - 7 VO2 Max MythConceptions: What Most People Get Wrong

KORR Medical Technologies — Tue, 03 Feb 2026 07:01:00 GMT

Get A Demo: https://korr.com/contact/video-demo/

VO2 max is having a moment—and with popularity comes misinformation. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the most common myths and misconceptions around VO2 max, why "more breath" usually isn't the problem, and how performance depends on far more than one number. They cover what's actually trainable, why wearables can mislead, how fat burning and VO2 max don't always move together, and why the best program isn't the most intense—it's the one you can recover from and repeat.

What you will learn

Why VO2 max is not "lung capacity," and what typically limits most people
How trainable VO2 max really is—and why "genetics" is often an excuse
Why VO2 max alone doesn't predict who wins (threshold, economy, utilization matter)
Why VO2 max matters for longevity and mortality risk—not just athletes
How Zone 2 and high-intensity work fit together (and why "moderate-hard" stalls progress)
Why higher VO2 max doesn't automatically mean better fat burning
Where wearables help, where they don't, and how to interpret the data responsibly
How metabolic testing can reduce guesswork and improve training decisions
