    Episode 387: Nathan T. Jenkins on Metabolic Flexibility, Aerobic Base, and First Principles
    2026/06/02
    In this episode of the Flex Diet Podcast, I sit down with Dr. Nathan Jenkins to discuss how to improve performance, body composition, and long-term health through the lens of aerobic development and metabolic flexibility. Nathan shares his journey from exercise physiology and coaching CrossFit athletes to his new role teaching physiology at the University of Georgia School of Medicine. We discuss why metabolic flexibility is such a powerful framework for understanding everything from biochemistry and exercise performance to metabolic disease. We also dive into interpreting maximal exercise testing data, including VO₂ measurements, EKG analysis, and near-infrared spectroscopy (NIRS), along with how different energy systems work together during training and competition. Nathan explains why building an aerobic base is critical for repeated high-intensity performance, how pacing impacts outcomes, and why the ability to "suffer" is actually a trainable skill. To wrap up, we cover practical strategies you can apply right away, including prioritizing protein and carbohydrates, improving sleep quality, and addressing common micronutrient deficiencies through blood work, such as magnesium, vitamin D, and omega-3 status.

  • Episode 386: Nervous System Regulation, Somatics, and Stress Resilience with Tracy Holemeyer

    Episode 386: Nervous System Regulation, Somatics, and Stress Resilience with Tracy Holemeyer
    2026/05/27
    In this episode of the Flex Diet Podcast, I sit down with my friend Tracy Holemeyer (Uncontrollably Me, host of the Other Way to See It podcast) to talk about healing and performance through nervous system flexibility, somatics, and self-awareness, especially with how much stress people are carrying right now. We dig into practical tools like orienting, grounding, the “starfish” drill, pendulation, and Tracy’s “core four” (soft eyes, relaxing the tongue, breath pacing for coherence, and soft knees), plus how posture and unconscious habits can shape mood and behavior. We also explore the value of community and coaching, how movement and sound (including humming, voo breath, and growling) can help regulate, and we finish with a thoughtful discussion on psychedelics, integration, and why support and discernment matter.

  • Episode 385: Rob Wilson on BJJ Performance Frameworks, Grip Training, Recovery Tech & The Check Engine Light Book

    Episode 385: Rob Wilson on BJJ Performance Frameworks, Grip Training, Recovery Tech & The Check Engine Light Book
    2026/05/18
    In this episode of the Flex Diet Podcast, I sit down with human performance specialist and coach Rob Wilson for a wide-ranging conversation that spans music, coach education, and what it really means to train for performance longevity. We dig into Rob’s new book, The Check Engine Light: Tune In Your Body and Mind to Achieve Performance Longevity, and his work educating coaches through ALTIS and with special operations communities. Rob also shares why jiu-jitsu strength and conditioning still lacks clear performance standards and proposes building sport-specific frameworks (like lower-body clinching demands) before jumping to exercise selection. We talk grip strength vs endurance, avoiding redundancy and tendon issues, contra-specific training for durability, and why “recovery” isn’t the goal—adaptation is—especially in elite sport.
