859 - Blood Flow Restriction with Dr. Michael MacPherson
Barbell Shrugged
In this episode of Barbell Shrugged, blood flow restriction specialist Dr. Michael MacPherson joins Doug Larson, Coach Travis Mash, and Dr. Mike Lane to break down how BFR training can be used for far more than post-injury rehabilitation. Michael explains how strategically restricting blood flow creates a hypoxic environment that increases type II muscle fiber recruitment, metabolic stress, and cellular swelling—even when training with relatively light loads. The result is a powerful tool for building or maintaining strength and muscle while reducing the mechanical stress placed on joints...

858 - Training Police Officers
Barbell Shrugged
In this episode, Doug Larson joins Coach Travis Mash and Dr. Mike Lane to break down what it takes to build a scalable strength and conditioning program for police officers. Mash shares his new partnership with the Winston-Salem Police Department, beginning with a six-week, 15-person pilot designed to refine onboarding, testing, training, and ongoing monitoring before expanding to roughly 600 officers and support staff. The team explains why tactical fitness must be built around a job-task analysis: officers may spend hours sitting in a patrol vehicle, then suddenly need to sprint, grapple,...

857 - The Protein Blueprint
Barbell Shrugged
In this episode, Doug Larson, Coach Travis Mash, and Dr. Mike Lane break down everything athletes need to know about protein: what it does, how much you actually need, and how to make it work in the real world. They dismantle the myth that the body can only use 30–35 grams per meal, explain why protein needs should scale with lean body mass and training goals, and show how distributing protein across three or four meals can support muscle growth, recovery, and performance without obsessing over a narrow post-workout window. The conversation then compares animal and plant proteins, whole...

Metabolic Adaptation w/ Dr. Eric Trexler, Doug Larson, Coach Travis Mash and Dr. Mike Lane #856
Barbell Shrugged
Dr. Eric Trexler returns to Barbell Shrugged to break down one of the most misunderstood subjects in fitness: how the body adapts to dieting, exercise, and energy restriction. Eric, a Duke University researcher with a PhD in Human Movement Science, joins Doug Larson, Dr. Mike Lane, and Coach Travis Mash to explain the constrained energy expenditure model, why cardio does not always produce the linear calorie burn people expect, and why the context of your diet matters. They cover metabolic adaptation, under-fueling in endurance and weight-class athletes, and why the body creates more friction...

Training For Aesthetics w/Doug Larson, Coach Travis Mash and Dr. Mike Lane #854
Barbell Shrugged
In this episode, Doug Larson, Dr. Mike Lane, and Coach Travis Mash break down the real-world science of training for aesthetics: getting leaner, building muscle, and looking better without losing sight of performance, health, and longevity. Mike opens with a wild DEXA scan story about breast implants and body composition testing, explaining how implants can skew lean mass and bone density numbers. The takeaway is simple: body composition tools are useful, but only when you understand what they are actually measuring. The crew then moves into the big rocks of physique change: nutrition,...

Scientific Research and CrossFit Workouts w/ Dr. Gerald Mangine, Doug Larson, Coach Travis Mash and Dr. Mike Lane #853
Barbell Shrugged
For years, one of the biggest criticisms of CrossFit has been that, Given every workout is different, it’s difficult to measure and track training stress in a meaningful way. Dr. Jerry Mangine joins Doug Larson, Travis Mash, and Mike Lane to discuss a decade of research aimed at solving that problem. Jerry breaks down how his team analyzed every CrossFit Open workout ever performed, developed equations to quantify workload across different movements, and created a system for classifying workouts based on total work performed and the rate at which athletes complete it. The conversation...

Peptides w/ Dr. Kyle Gillett, Doug Larson, Coach Travis Mash and Dr. Mike Lane #852
Barbell Shrugged
Peptides have exploded in popularity over the last few years, but separating legitimate science from marketing hype has become increasingly difficult. In this episode, Dr. Kyle Gillett joins Doug Larson, Dr. Mike Lane, and Coach Travis Mash for a deep dive into the world of peptides, growth hormone secretagogues, GLP-1 medications, and emerging therapies that may shape the future of performance, recovery, body composition, and longevity. They unpack what peptides actually are, which compounds have meaningful clinical research behind them, and where caution is still warranted, especially when...

Training Tactical Athletes w/ Doug Larson, Coach Travis Mash and Dr. Mike Lane #851
Barbell Shrugged
In this episode, Doug Larson, Dr. Mike Lane, and Coach Travis Mash break down what it actually means to train tactical athletes such as police officers, firefighters, military personnel, SWAT teams, cadets, and first responders who may be called into high-stress physical situations at any time. The conversation starts with the Enhanced Games and the reality of performance-enhancing drugs in sport, then quickly shifts into the tactical world, where “second place” can mean getting hurt, losing control of a situation, or not making it home. Mike explains why the first step is always a...

How to Train Hard Without Breaking Down with Mike Robertson, Doug Larson, Dr. Mike Lane and Coach Travis Mash #850
Barbell Shrugged
In this episode, strength coach, educator, and IFAST co-founder Mike Robertson joins Doug Larson, Dr. Mike Lane, and Coach Travis Mash to talk about how serious lifters and athletes can train hard without destroying their bodies in the process. Mike shares his path from early T-Nation contributor to gym owner and longtime coach, explaining how his background in biomechanics shaped the way he evaluates movement, manages athletes, and builds training systems that support long-term performance. The crew also reflects on the early 2000s strength culture, the lessons learned from powerlifting, and...
info_outlineIn this episode of Barbell Shrugged, Doug Larson is joined by longtime co-host Travis Mash and new co-host Dr. Mike Lane for a return visit from one of the show’s most popular guests, Dr. Tommy Wood. Tommy breaks down the core thesis of his new book, The Stimulated Mind (releasing March 24), which uses dementia prevention as the headline but is really about boosting cognition at every stage of life. 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 that “optimization” only works when it fits real life, and that the brain adapts like the body: sleep, nutrition, and exercise support it, but you still have to “train the brain” with demanding learning and skills. He outlines a practical learning dose-response, roughly 30–90 minutes of deep challenge per session, 2–3 times per week as a sweet spot for consolidation, while acknowledging the power of daily touchpoints for habit formation (Doug’s Duolingo streak and the “don’t break the chain” approach). From there, they go deep on exercise modalities and cognition: aerobic work and interval training improving hippocampal function (memory), high-intensity work potentially driving brain benefits through lactate → local BDNF, and coordinative/open-skill sports (racket sports, dancing, martial arts) producing outsized brain returns for the same physical strain.
The conversation closes with a fast but important run through risk, genetics, and lifestyle: Tommy explains ApoE4 as a risk multiplier that’s highly environment-dependent, amplifying bad inputs (inflammation, poor metabolic health) but also amplifying the benefits of doing the basics well. They hit the big nutrition levers for cognition; omega-3s, key B vitamins (methylation), vitamin D, iron, plus polyphenol-rich foods (berries, cocoa, coffee/tea), and squash the common “red wine” rationalization by emphasizing net outcomes (sleep and brain volume matter). Finally, Tommy emphasizes the under-rated keystone: social connection and pro-social behavior, arguing that the Mediterranean “diet” is really a Mediterranean lifestyle, and that isolation can erase many of the benefits of even a perfect nutrition plan.
