Perform with Dr. Andy Galpin

In this episode, my guest is Dr. Ben House, a nutritional scientist who has spent nearly two decades working with elite athletes and professional sports teams. We take a detailed look at testosterone, what your lab results can and cannot tell you, and why a higher number does not automatically mean better health or more muscle. Ben explains total and free testosterone, sex hormone-binding globulin...

In this episode, my guest is Dr. John Rusin, a physical therapist and strength coach who bridges rehabilitation and human performance. We discuss his approach to persistent back, shoulder, and knee pain and how to build a body that can handle demanding training for the long term. John walks through his six-phase warm-up, a 10–12-minute sequence that combines foam rolling, stretching, corrective ex...

In this episode, my guest is Dan Garner, a renowned human performance coach behind UFC champions, Olympic medalists, and CEOs. We discuss how he bridges the gap between sports science and real-world coaching. Dan explains constraint theory — finding the single bottleneck holding someone back — and walks through the blood markers he uses to find it, including why a 20% testosterone swing can be pur...

In this episode, I answer your questions on nutrition, hydration, and recovery in our second audience Q&A. I start with what I call the 90%: the principles nearly every effective nutrition plan shares, from food quality and caloric balance to fiber targets, vegetable volume, color variety, and liquid calories. I then cover the four elements of fueling around training, glucose, amino acid availabil...

In this episode, I answer your questions in the first-ever open Q&A on Perform, working through the five themes that came up most. I start with how I think about training for longevity—why being well-rounded and resilient matters more than chasing any single marker like grip strength or VO2 max. From there, I break down the basics of training for muscle, strength, and fat loss, including the simpl...

In this episode, I sit down with Dr. Mike Roberts, Professor in the School of Kinesiology at Auburn University, and one of the most respected muscle physiologists, to explain how muscle actually grows. Mike shares that mechanical tension—not hormones, metabolic byproducts, or muscle damage—is the primary driver of hypertrophy. We cover why testosterone and androgen receptors don't necessarily pred...

In this episode, I tackle muscle asymmetries and imbalances — when the differences between your two sides help you, when they hurt you, and what to actually do about them. I move past the popular "10% rule" and walk through my three I's framework: how to investigate asymmetries across morphology (muscle size and shape), quality (fat infiltration inside the muscle), and functionality (strength, pow...

In this episode, I sit down with Dr. Lauren Colenso-Semple to examine what the science says about female-specific training and nutrition. We discuss why so little research has historically focused on women, what makes menstrual cycle research so difficult and expensive to run, and what her own dissertation found when she measured muscle protein synthesis across cycle phases. Dr. Colenso-Semple exp...

In this episode, I sit down with Dr. Sam Harris to discuss how attention, mindfulness, and clear thinking shape performance. We start by separating intelligence from wisdom, then look at how modern technology is rewiring our attentional capacity — including which tools enhance cognition and which compete with it. Sam walks through three approaches to working with the mind: training concentration,...

In this episode, I cover "athlete's heart" — the paradox where the same cardiovascular adaptations that make endurance athletes exceptional can also mimic, and sometimes mask, real risk. I trace the history of what’s now known as exercise-induced cardiovascular remodeling (EICR), and walk through what's actually happening structurally, functionally, and electrically in a trained heart. I separate...

In this episode, I sit down with Ken Rideout — author, elite masters marathoner, and one of the most compelling people I've ever had on the show — to discuss his journey from a difficult childhood and decade-long opioid addiction to becoming the Masters (50+) Marathon World Champion and winning the Gobi March, a 155-mile self-supported stage race across the Gobi Desert in Mongolia. Ken shares how...

In this episode, I sit down with Dr. Lenny Wiersma — one of the most respected and quietly influential figures in sports psychology — for a conversation on what it actually takes to perform when the stakes are highest. A professor for over 25 years and a highly published scientist, We discuss Alex Honnold's recent skyscraper climb and unpack what's really happening psychologically at the absolute...

In this episode, I break down everything you need to know to build a strong core and better-looking abs — and explain why most people are training them wrong. I start by clarifying the difference between "abs" and "core," covering the key muscle groups involved (rectus abdominis, obliques, transverse abdominis, spinal erectors, and more) and debunking the myth that these muscles require uniquely h...

In this episode, I explain how to increase your control over your nervous system — not just to manage stress, but to recalibrate your autonomic nervous system for long-term physiological resilience and adaptability. This episode goes beyond basic stress management techniques to explore how to fine-tune your nervous system, become more stress tolerant, and use your personal data to know exactly whe...

In this episode, my guest is Jill Miller, a renowned fascia expert and teacher of breathwork practices and self-myofascial release (SMR) to improve mobility, reduce pain, and enhance body awareness. We discuss how fascia—the connective tissue in and around muscles, bones and organs—is essential for flexibility and movement, and we explore how tools like foam rollers, balls, massage and cupping can...

My guest is Dr. Michael Ormsbee, Ph. D., a professor of nutrition and integrative physiology and the director of the Institute of Sports Sciences and Medicine at Florida State University. We explore how pre-sleep nutrition affects fat metabolism, muscle growth, performance, and recovery, while helping individuals meet their daily protein goals without causing weight gain. We discuss what to eat at...

In this episode, my guest is Dr. Allison Brager, Ph. D., an active-duty Army neuroscientist whose research focuses on physiological resilience in extreme stress environments such as Antarctica and outer space. We discuss how sleep is impacted in these harsh conditions and the broader concept of sleep resilience, which is crucial for athletes, military personnel, and anyone with demanding personal...

In this episode, I discuss the importance of exercise, specifically strength training, for kids. With growing concerns over childhood obesity, limited opportunities for physical activity in school, decreased outdoor playtime, and reduced sports participation, the lack of physical activity in children poses serious long-term risks to their physical and mental health. I address common myths and misc...

My guest is Dr. Herman Pontzer, Ph. D., a professor of evolutionary anthropology and global health at Duke University, known for his research on human bioenergetics, particularly energy expenditure and the exercise paradox.
