In this episode, Cameron Garber dives deep into metabolic testing with Stephen Olson, founder of Benchmark Body Metrics. Discover why your smartwatch's VO2 estimate might be 20% off, how to build an aerobic base that transforms endurance performance, and the often-overlooked breathing patterns that limit fitness gains.

From testing Everest summiteers to diagnosing why runners plateau despite consistent training, Stephen reveals the clinical secrets that separate generic fitness advice from data-driven results.

You Will Learn:

• Why VO2 max correlates with longevity (and what it actually means)
• The 3 metabolic testing methods that replace guesswork in your training program
• How to identify your true fat-burning zone—without an expensive device
• The respiratory limitation that cost one Boston Marathon qualifier 2 years of progress
• Why testing yourself 200+ times is the fastest path to coaching mastery
• How to use metabolic data to sell premium coaching packages (business angle)
• The fat oxidation graph that makes clients immediately "get" their training zones
• Why 95% of people will choose premium packages when you show them this data first

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")

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

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

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

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

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
