The crew sets the tone early: brain health is not “old people stuff,” it’s performance, learning, and resilience, built daily through how you live and how you train. Tommy makes the case...

How Circadian Rhythms Shape Strength, Recovery, and Health with Dr. Karen Esser #829
Barbell Shrugged
In this episode, Dr. Karen Esser Professor and Chair of the Department of Physiology and Aging at the University of Florida joins the crew to break down one of the most overlooked performance variables in human physiology: circadian timing. After a career spent studying muscle adaptation, Dr. Esser shifted her research toward the molecular clocks inside our tissues, uncovering how every cell in the body keeps its own time. She explains how these clocks govern fuel storage, protein repair, metabolic readiness, and ultimately the way muscle responds to training. The team digs into what these...

Menopause, Weight Gain and Hormones with Fat Loss Expert Dr. Bill Campbell #828
Barbell Shrugged
In this episode, Dr. Bill Campbell returns to the show to discuss a major pivot in his research from building muscle and optimizing fat loss to understanding menopause and its effects on women's body composition. After watching his wife struggle through a severe perimenopause transition that resisted every traditional fat loss strategy, Campbell uncovered a massive blind spot in the scientific literature: almost no research exists on fit, resistance trained women going through menopause. His public comments sparked hundreds of messages from women describing the same struggles including...

Measuring Muscle Mass Percentage with Dr. Chris Perry, Anders Varner, Travis Mash and Doug Larson #823
Barbell Shrugged
In this week’s episode of Barbell Shrugged, Anders Varner, Doug Larson, Coach Travis Mash, and Dr. Chris Perry dive deep into the real science of muscle mass, why it’s the single most important tissue in the human body and what happens when you don’t have enough of it. They cover everything from how muscle mass impacts disease risk, hormone balance, metabolism, and injury prevention to why being “under-muscled” may be just as dangerous as being overweight. Dr. Perry explains how strength training and nutrition can reverse age-related muscle loss and why the decade between your...
info_outlineIn this episode of Barbell Shrugged, Doug Larson is joined by longtime co-host Travis Mash and new co-host Michael Lane as they welcome back John Rusin for his first appearance on the show in five years. The conversation opens with a candid transition moment for the podcast, acknowledging Anders Varner’s departure and setting the stage for a new chapter of Barbell Shrugged. From there, the crew dives straight into Rusin’s background in sports performance, physical therapy, and global coaching, including his work with elite athletes, Olympic committees, and thousands of coaches through his Pain-Free Performance system.
The heart of the episode centers on biomechanics, individual anatomy, and why “one-size-fits-all” coaching models fail athletes over the long term. Rusin breaks down how differences in femur length, hip structure, and torso proportions radically change how people should squat, hinge, and load movements. The group explores why goblet squats are one of the most universally joint-friendly tools, how assessment should guide exercise selection, and why chasing perfect technique without context often leads to chronic pain. The discussion also highlights the importance of strategic variability, offseason training, and removing aggravating patterns rather than blindly pushing through discomfort.
The episode closes with a deep look at Rusin’s new book Pain-Free Performance, a multi-year project born out of burnout, injury, and a desire to preserve his system in a lasting format. Rusin explains who the book is for, coaches, athletes, and everyday people alike, and why long-term health, movement quality, and consistency ultimately drive performance and longevity. From youth sports specialization to elite training volume and survivorship bias, this episode delivers a grounded, experience-driven perspective on how to train hard, stay healthy, and perform at a high level for decades, not just a season.
