When it comes to performance, more isn’t always better. In this episode, I sit down with conditioning expert Joel Jamieson to explore the science of recovery, aerobic fitness, and how to use heart rate variability (HRV) to train smarter. They dive into why elite athletes recover so quickly, the long-term value of zone 2 training, and how HRV reflects your resilience—not just your readiness. Joel shares lessons from two decades of working with fighters, Olympians, and NFL players, along with powerful insights from his own cardiovascular health journey. Whether you’re a high performer or simply want to live longer and stronger, this episode is packed with practical takeaways.

In this episode, you’ll learn:

• What HRV actually tells you—and what it doesn’t
• Why aerobic fitness is one of the strongest drivers of recovery and longevity
• The surprising downside of too much strength training
• How to monitor training load and avoid overtraining
• Why lifestyle stress matters more than your workout

This episode will change the way you think about training—and reveal why recovery deserves a central role in your performance strategy.

In this episode, I’m joined by Dr. Ty Beal—global nutrition researcher and Senior Technical Specialist at the Global Alliance for Improved Nutrition (GAIN)—to uncover the hidden epidemic of micronutrient deficiencies worldwide. From food access and affordability to ultra-processed diets and nutrient bioavailability, we explore how modern food systems are failing billions and what needs to change to truly make the world healthier.

We cover:

• Why 3 billion people can’t afford a healthy diet—and how that affects nutrient status
• The most common global and U.S. micronutrient deficiencies (and why they’re often overlooked)
• Why women and children are especially vulnerable during pregnancy, infancy, and adolescence
• The role of ultra-processed foods in displacing nutrient-rich options
• How bioavailability, anti-nutrients, and the “food matrix” impact your real nutrient intake
• Why plant-based diets aren’t always safer—and the hidden risks of nutrient shortfalls
• The science behind biofortification, food system reform, and why animal-source foods stil matter
• What the U.S. gets wrong about food guidelines, global trade, and nutritional equity

Whether you care about maternal health, child development, or just making better nutrition decisions, this is a vital conversation about nutrient density, food justice, and global health.

Who is Dr. Ty Beal?

Dr. Ty Beal is a Senior Technical Specialist and global nutrition scientist at the Global Alliance for Improved Nutrition (GAIN) where he leads research on global food systems, nutrient inadequacy, and diet quality. His work bridges science and policy to help address the world’s most pressing nutrition challenges—especially among vulnerable populations.

In today's episode, I had the chance to speak to muscle physiology researcher and science communicator Dr. Lauren Colenso-Semple. Together, we unpack the common claims around hormones and training—from whether you should change your workouts based on your cycle, to the real effects of fasted cardio and birth control on performance and muscle growth. We also explore how menopause affects body composition, what the science actually supports when it comes to training differences between men and women, and why some of the most persistent myths about women’s physiology are based more on assumption than evidence.

What You’ll Learn:

• Why women’s physiology is not a limitation for building muscle
• Whether training around your menstrual cycle or avoiding fasted workouts is necessary
• The truth about oral contraceptives and their impact on performance, hypertrophy, and strength
• How menopause affects body composition—and what you can do about it
• Why consistency and progressive overload matter more than hormone fluctuations
• How much protein and resistance training women actually need—and when to eat it

This conversation is for every woman who’s been told her physiology is too complicated to train effectively. It’s not. The science is finally catching up—and Lauren is helping lead the charge.

In this episode, I’m joined by Dr. Abbie Smith-Ryan—one of the leading researchers in exercise physiology and women’s metabolism—to unpack the science of how women should be training through perimenopause, postmenopause, and beyond. We dive into the physiological changes that impact body composition, performance, and recovery—and how to adjust training and nutrition to match.

We discuss:

• How high-intensity interval training (HIIT) improves VO₂ max, fat oxidation, and muscle quality in women
• Whether fasted training helps or hurts, and why so many women are under-fueled
• What the science really says about lifting heavy and building muscle over 40
• Nutrient timing, rest intervals, and why sex-based differences in physiology matter
• What we still don’t know about hormone therapy, protein needs, and female-specific adaptations

If you’re navigating training, muscle loss, or metabolic changes through midlife, this conversation will give you clarity, confidence, and evidence-based strategies you can actually use.

In this episode, I’m joined by Dr. Melanie Cree—physician-scientist, pediatric endocrinologist, and one of the leading researchers redefining how we understand and treat Polycystic Ovary Syndrome (PCOS). PCOS affects millions of women, yet it's still underdiagnosed, misunderstood, and often mistreated. Dr. Cree cuts through the confusion, offering a deeply scientific yet compassionate look at what’s really driving this complex condition—from insulin resistance and mitochondrial dysfunction to skeletal muscle quality and fertility trajectories across a woman’s lifespan.

We cover:

• Why PCOS isn’t a single disease—and what two phenotypes may explain the full picture
• How muscle, liver, and fat interact in PCOS
• The misunderstood role of testosterone, insulin, and SHBG in diagnosis
• What muscle biopsies reveal about teenage girls with PCOS
• Intramuscular fat, mitochondrial impairment, and the true cost of sedentary muscle
• How early lifestyle and exercise interventions could change the future of PCOS care
• What GLP-1 agonists and amino acid supplements might offer for treatment

Whether you’re a clinician, patient, or advocate for women’s health, this episode will give you a whole new lens on PCOS—and why skeletal muscle may be the most overlooked (and powerful) organ in the conversation.

Who is Dr. Melanie Cree?

Dr. Melanie Cree is a board-certified pediatric endocrinologist and Associate Professor at the University of Colorado and Children’s Hospital Colorado, where she directs a leading multidisciplinary PCOS clinic. Her research bridges metabolic medicine and muscle physiology, with clinical trials exploring semaglutide, amino acid therapy, liver metabolism, and insulin resistance in adolescents.

Jeff Krasno’s personal health transformation—reversing diabetes, shedding 60 pounds, and reclaiming his health at age 50—is a masterclass in what he calls “good stress.” In this episode, we dive into the simple but powerful idea that discomfort might just be the medicine we all need. Jeff, the founder of Commune and host of the Commune podcast, shares how fasting, cold exposure, resistance training, and attention to modern habits helped him regain his energy, build muscle, and thrive.

Together, we discuss how metabolic dysfunction has become the norm, how adaptive stress responses can be harnessed to reverse chronic illness, and why building muscle is not only the antidote to obesity but also a critical factor in longevity. If you’re interested in reclaiming your vitality and learning how to work with—not against—your biology, this episode will speak to you.

We cover:

• Jeff’s story of personal health transformation at midlife
• What “good stress” is and how to harness it to improve health
• Why chronic ease leads to chronic disease
• Cold therapy, fasting, and training as adaptive stressors
• The importance of resistance training for blood sugar control
• How metabolic dysfunction hides in plain sight
• Practical tips to increase non-exercise activity thermogenesis (NEAT)
• Building muscle as the path to longevity and disease prevention
