RP Strength Podcast

Dr. Eric Trexler, an exercise scientist who studies supplements and performance nutrition. He discusses why caffeine is so common in fitness. He talks about dosing by bodyweight, how tolerance and habituation reduce effects, timing and delivery forms like gum or pills, and practical strategies to resensitize use without wrecking sleep.

Dr. Mike T. Nelson, an exercise physiologist and biomedical engineer who studies HRV and recovery. He explains what HRV measures and how training stress changes it. He discusses using HRV to time deloads, when to intentionally train low-HRV days for resilience, and practical recovery tactics plus wearables and measurement caveats.

Dr. Milo Wolf, exercise scientist researching hypertrophy and training to/past failure. He explains why working near failure boosts growth. Practical methods covered: partials, drop sets, and cautious cheat reps. Talks study findings, deloading strategies, injury risk context, and time-efficient ways to get comparable gains.

Dr Pak, a physician and fitness educator known for evidence-based takes on body composition, debunks measurement myths. He explains why scans disagree and why waist measures, photos, and gym progress matter. They discuss how body fat relates to muscle gain, sensible bulking, and why maintenance is hardest. Practical tracking beats obsessing over single tests.

Dr. Mike T. Nelson, exercise physiologist and researcher focused on metabolic flexibility and HRV. He breaks down fuel switching and how training and fasting affect fat burning. He explains why carbs power high-intensity work. Learn when fasted cardio helps, how to use HRV to guide cardio, and why improving VO2 max aids recovery.

Ethan Suplee, actor known for major film and TV roles who lost hundreds of pounds and sustained changes, shares his long weight-loss journey. He recounts hitting 536 lbs, the simple rule that started change, discovering a calorie framework, the surprising difficulty of maintenance, distinctions between types of hunger, and his perspective on GLP-1s and habit-based longevity.

Dr. Milo Wolf, exercise physiologist and PhD researcher on range of motion and hypertrophy. He discusses why stretch-position partials drive more muscle than shortened partials. Talks bulking pitfalls and practical ROM programming. Covers tempo, eccentric control, soreness, and when to use partials for max hypertrophy.

Will Glassner, an athlete with spastic diplegic cerebral palsy who lifts and competes with adaptive strategies, shares his approach to training and life. He talks about what CP looks like day to day. He covers smart exercise choices instead of barbell squats, unilateral work, machines, mobility tweaks, and practical bulking and protein habits.

Dr. Pak, a PhD researcher on minimum effective dose for strength and hypertrophy and educator, breaks down why small, consistent doses of training work. He tackles volume tribalism, the “52 sets” misconception, and the core 3–5 must-haves like effort and consistency. Expect clear takes on realistic physique expectations and flexible exercise selection.

Dr. Eric Trexler, exercise scientist and researcher at Duke, breaks down talent development and training science. He critiques early specialization and the 10,000-hour myth. He explains how playing multiple sports boosts learning, reduces burnout and injury, and why junior stars often differ from adult elites. He offers practical timing for when focused commitment really pays off.
