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...

Black Root Recovery: The Multi‑Modality Recovery Sauna Built for Veterans, Athletes, and High Performers #827
Barbell Shrugged
Former Marine and general contractor Andrew Kavanaugh joins the crew to share the origin story of Black Root Recovery, a company he founded after watching too many of his fellow Marines struggle physically, mentally, and emotionally after returning home. What started as a personal quest to rebuild his health led to a 90-pound weight loss, the elimination of sleep apnea and nightmares, and a profound shift in cognitive clarity and emotional resilience. Andrew combined the modalities that changed his own life (grounding, infrared therapy, red-light therapy, and traditional sauna heat) into a...

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_outlineFormer Marine and general contractor Andrew Kavanaugh joins the crew to share the origin story of Black Root Recovery, a company he founded after watching too many of his fellow Marines struggle physically, mentally, and emotionally after returning home. What started as a personal quest to rebuild his health led to a 90-pound weight loss, the elimination of sleep apnea and nightmares, and a profound shift in cognitive clarity and emotional resilience. Andrew combined the modalities that changed his own life (grounding, infrared therapy, red-light therapy, and traditional sauna heat) into a single premium, custom-built recovery system designed to reduce inflammation, support brain health, and help veterans and high performers reclaim their capability.
Andrew breaks down the science and practical application behind each component of the system, including his patented grounding design that connects the user directly to an eight-foot copper ground rod to immediately reduce blood viscosity and "electrical noise" in the body. Paired with deep-penetrating red light panels, infrared heat, and a high-output traditional sauna, his units create a stacked recovery environment that improves circulation, reduces inflammation, accelerates healing, and enhances cognitive performance. Andrew shares how, after three months of daily use, he saw his social anxiety disappear, his brain function sharpen, and his jiu-jitsu endurance skyrocket.
The conversation expands into the broader mission: supporting veterans, giving athletes a competitive performance advantage, and scaling access to recovery tools that have historically been too expensive or too fragmented to deliver real transformation. Andrew discusses future plans to build custom installations for gyms and sports teams, and continue refining the multimodal system. Whether the goal is longevity, recovery, or helping those who have served, this episode reveals why integrated recovery environments may become the next frontier in reducing inflammation, healing trauma, and elevating human potential.
