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 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

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.

• 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)

After four kids in six years and a stall-out on the scale, Shannon swapped punishment-style workouts for CardioCoach-guided heart-rate training. The result? Fewer injuries, steady weight loss, and marathon negative splits—plus the confidence to pace race day by physiology, not pace charts. Dr. Marc and Dr. Cameron break down her test data (why living in the 130s mattered), the 70/30 approach, and how "show up easy" beats "go hard or quit" for long-term wins.

What You'll Learn (this episode):

• How to translate a metabolic test into actionable HR zones (including fat-max)

• A step-by-step marathon HR strategy (130s → mid-140s/150s → 160s+ for the close)

• Why easy days curb hunger, improve recovery, and make intensity days work

• How to use HR drift to detect fatigue, illness, or under-recovery—before it derails you

• Turning "scale only" progress into performance metrics you can control and enjoy

• The consistency playbook: daily "show up" rules, flexibility, and avoiding injury layoffs

• How zones "expand" over time—running faster at the same heart rate without feeling harder

• Why you should "get tested now" (not later) to break the plateau loop and build momentum

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

"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.

• 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.

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.

• 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.

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.
