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.

• How Richard Diaz built his career from a closing YMCA to a global reputation as the coach behind world champions.

• Why hybrid athletes thrive with "lower" VO₂ scores and what that means for your own training.

• The role of gait analysis and bike fitting in unlocking efficiency and reducing the cost of work.

• How VO₂ and RMR testing act like a crystal ball, revealing past training, current capacity, and future potential.

• The real difference between aerobic vs. anaerobic demands in sports like triathlon, Spartan racing, and HYROX.

• Why zone 2 isn't enough—and how to train specifically for your sport's demands.

• The psychology of performance from Richard's book Flow: overcoming resistance, managing the CNS, and entering the zone.

• Why testing isn't just for elites—how everyday athletes can benefit just as much from proper assessment.

VO₂ max gets all the headlines, but it's only one piece of the story. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the full VO₂ results dashboard: VO₂ max, aerobic and anaerobic thresholds (VT1/VT2), heart-rate zones, heart-rate recovery, and how these metrics connect to cardiometabolic health, mortality risk, and healthspan. You'll also learn why "lactic acid burn" is a myth, how body weight changes can shift VO₂ max, and practical ways to individualize zones beyond generic percentage formulas—using real data from CardioCoach.

Who it's for: coaches, clinicians, gym owners, endurance athletes, and anyone who wants to train smarter, live longer, and make VO₂ testing useful outside the lab.

You'll learn:

• What VO₂ max actually measures—and why higher isn't always "better" without context

• How aerobic vs. anaerobic thresholds (VT1/VT2) mark intensity changes and guide training

• Why lactate is fuel (not "the burn") and what really drives that burning sensation

• The case for individualized heart-rate zones vs. one-size-fits-all percentages

• How heart-rate recovery flags autonomic balance and cardio efficiency (key cutoffs to know)

• The link between fitness "METs" and reduced all-cause mortality—and what that means for healthspan

• Practical programming: blending Zone 2 base with Zone 4–5 intensity for maximal adaptation

• How CardioCoach streamlines testing and makes results coachable and repeatable

Periodization doesn't have to be complicated. In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber break down the essentials of periodization, how to structure your training across the seasons of life and year without getting lost in the jargon. They explore how to zoom out for long-term health goals (like still being active at 90) and zoom in to align your workouts with the activities you love.

You'll learn:

• How to use the "seasons of life" to make fitness realistic and sustainable.

• Why balancing training and recovery is the key to long-term progress.

• The role of VO₂ and RMR testing in tailoring your training cycles.

• How to shift strength, cardio, plyometric, and skill work across the year.

• Why 80/20 training is critical for avoiding injury and burnout.

• How to adapt your plan to fit real-life stressors, time, and goals.

Whether you're a weekend warrior, a competitive athlete, or someone who simply wants to age well, this episode will help you simplify your approach and stay consistent for decades to come.

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber take a deep dive into how to train for a long, healthy, and active life. Instead of obsessing over quick results or "goal metrics," they explain why focusing on sustainable "process metrics" creates better outcomes over decades—not just weeks. You'll learn how to set up your training, recovery, and lifestyle habits so you can stay in the game for years, avoid burnout and injury, and keep doing the activities you love at every stage of life.

What You'll Learn in This Episode:

• The key differences between goal metrics (e.g., weight loss, race times) and process metrics (e.g., heart rate zones, sleep quality).

• Why consistency beats intensity for long-term health and performance.

• How to build a 30-year health plan that balances exercise, recovery, nutrition, and stress management.

• How VO2 testing and heart rate zones help personalize training for better results.

• The 80/20 principle for polarized training and why it prevents burnout and injury.

• How to adapt your training through life's seasons without losing progress.

• Why "starting where you're at" matters more than jumping to your end goal.

• Ways to spot and address early warning signs of overtraining, fatigue, or poor recovery.

• How to measure success by moments and experiences—not just numbers.

• Why building supportive habits and environments beats chasing quick fixes.

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber reveal how a VO₂ test can tell the full story of your fitness — past, present, and future. While most people think VO₂ max is the whole picture, they explain how measuring both oxygen consumption and carbon dioxide production unlocks deeper insights into fat-burning efficiency, training zones, and metabolic health.

From weekend warriors to elite athletes, you'll hear how VO₂ testing can uncover hidden patterns that may be holding you back, why "moderate" workouts often stall progress, and how to optimize training using the 80/20 principle. Through real client stories, Marc and Cameron show how data can guide smarter workouts, better recovery, and sustainable results — all while taking the blame off the athlete and focusing on aligning fitness efforts with personal goals.

Whether you want to get faster, burn more fat, recover better, avoid injury, or simply feel great for decades to come, this episode delivers the science, strategy, and encouragement to train for your future self.

In this episode of Metabolic Mastery, Dr. Marc Humbert and Dr. Cameron Garber dive deep into the science of longevity—what it means, why healthspan matters more than just living longer, and how metrics like VO₂ max and muscular power can help predict and improve your quality of life as you age.

They explore the difference between lifespan and healthspan, debunk common longevity "hacks," and make the case for habits over shortcuts. Using clear visuals (including the now-famous "squared curve" concept), practical examples, and even the inspiring story of Grandma Betty, they lay out the true foundation of healthy aging: strength training, cardiovascular fitness, sleep, nutrition, and meaningful connection.

Whether you're a health practitioner, fitness enthusiast, or simply want to age with vitality, this episode offers an evidence-based, empowering guide to increasing both your years—and the life in those years.
