    Testosterone Explained (Low T, Muscle Growth, Aging & TRT) | Dr. Ben House

    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 (SHBG), and how testing methods, sleep, hydration, meals, and the timing of your blood draw can affect the result. We examine research on testosterone and muscle growth, why population averages can obscure individual differences, and how metabolic health complicates the story of testosterone and aging. We also discuss obesity, low energy availability, dietary fat, carbohydrates, micronutrients, and recovering after a calorie deficit. Ben shares his approach to investigating low testosterone, the importance of informed consent before testosterone replacement therapy (TRT), and the distinction between restoring normal levels and using higher doses for performance or physique goals. We finish with lessons from professional sports on managing training loads, fueling, sleep, and recovery. This episode is for anyone who wants to better understand hormone testing, support long-term performance, and make more informed decisions about testosterone.

    How to Train Without Pain (Back, Shoulders, Mobility & Strength) | Dr. John Rusin

    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 exercises, activation, movement practice, and explosive drills. He explains why breathing matters during soft tissue work, how mobility differs from flexibility, and why feeling tight doesn't necessarily mean you just need more stretching. We cover simple movement breaks for desk workers, detailed cues for hip and shoulder stability, face-pull technique, bracing, lifting belts, and how to adapt exercise form to your body and goals. We also discuss progressing back to heavier training, maintaining strength, muscle, and power as you age, and using loaded carries to build and assess full-body capacity. This episode is for anyone who wants to move more comfortably, train consistently, and keep getting stronger.

    How to Reach Your Fitness Goals (Hard-to-Grow Muscles, Lose Fat, Busy Schedule & More) | Dan Garner

    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 pure noise, why vitamin D has no usable reference change value, and why the omega-3 index is the most honest marker he tracks. We cover his three-step approach to fat loss, diet breaks, low energy availability, hypertrophy clusters, deload strategy, and an evidence-first framework for evaluating peptides. This episode is for anyone who wants to measure what they're doing and adjust it intelligently rather than guessing.

    The Fundamentals of Nutrition, Hydration & Performance Fueling

    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 availability, hydration, and GI distress, including the Galpin Equation for fluid intake during exercise. I walk through the three-step process I use to coach nutrition, which begins by adding nutrients rather than restricting them, and I explain when body recomposition is possible, what the protein data actually support, and why strength training is a bigger signal for muscle growth than protein. I close with what separates high performers from everyone else: energy management. This episode is for anyone who wants the fundamentals before the fine-tuning.

    The Fundamentals of Training for Muscle, Strength & Longevity

    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 simple rules I use for each: the 72-hour rule for hypertrophy, the 3-to-5 rule for strength, and the 5-4-3-2-1 rule for fat loss. I then walk through my exact process for program design, what "functional" training really means, and where AI is actually useful—and where it falls short—for your health and performance. This one is for anyone who wants a clear, practical foundation for building their own training.

    What Drives Muscle Growth & What Doesn't | Dr. Mike Roberts

    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 predict muscle growth, what separates high responders from low responders, and how these “low responders” should train to best get results. We also work through training volume, load versus reps, lengthened partials, aging and anabolic resistance, and the interference effect between strength and endurance training. If you want to understand the real science of building muscle, this conversation is for you.

    Identify & Fix Muscle Imbalances & Injury Risks 

    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, power, and movement); how to interpret the data using context rather than blanket numbers; and how to intervene with a practical five-step correction program built around unilateral training and plyometrics. I cover testing tools from tape measures to MRI, the research on grip-strength asymmetry and aging, and why lower-body asymmetries warrant more attention than upper-body ones. This is for athletes, coaches, and anyone who moves and wants to reduce injury risk or perform at their best.

    Female Training, Hormones & Nutrition: Fact vs. Fiction | Dr. Lauren Colenso-Semple

    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 explains the real hormone fluctuations of the menstrual cycle, why testosterone matters far less for women's muscle than people assume, and why men and women gain strength and size at the same relative rate at any age, including through menopause. We also cover low energy availability, scientific literacy, and how to figure out what works for you.
