    Ep 131: Born to Run, or Born to Walk? Mark Sisson on the Movement Your Body Really Wants

    Most of us were told that running is the purest path to leanness, heart health, and a long life. Mark Sisson spent a career as an elite endurance athlete, becoming a sub-2:18 marathoner and top finisher at Ironman, before his own body forced him to question all of it. In this conversation, he makes the case that – for many people – "chronic cardio" quietly breaks the body down more than building it up, and that the movement your body is actually engineered for is one that we have stopped respecting: walking. In this episode, we get into: The broken promises of running for exercise, including injury rates, the fat loss myth, hormonal dysfunctions, and more Real aerobic training and why the fastest marathoner on earth trains 80% of the time at an easy, conversational pace Why persistence hunting was never a steady-state jog, but more of an alternating walking-climbing-sprinting endeavor How modern shoes "brace and encase" our feet, dulling our connection to the ground and setting up injuries What a fitness routine looks like when it aligns with evolutionary biology Mark is 73 and, by his own account, fitter than he's ever been. This makes him one of the rare voices on aging who is living the message in real time. If you want to understand a sustainable framework for fitness and longevity, this episode will clarify how you think about it.

    Ep 130: First Move Well, Then Move Often: Gray Cook on Functional Movement

    As a physical therapist and creator of the Functional Movement Screen (FMS), Gray Cook has spent more than 30 years changing how we think about human movement. In this episode, recorded at the Functional Movement Systems headquarters in Chatham, Virginia, Garrett sits down with Gray for a wide-ranging conversation on what "functional" actually means, why most of us are chasing symptoms instead of causes, and how to build a body that moves well for life. If you've ever wondered why your training isn't translating into real-life movements or why pain keeps coming back, this episode is for you.  We cover: Why Gray defines "functional" as simply meaning "good enough" in the most important areas that influence musculoskeletal health. How movement screening is a status check for the musculoskeletal system, just like we take blood pressure for the cardiovascular system and use an eye chart for the visual system. The value of "regressing to progress" by working through the developmental phases: roll → crawl → kneel → squat → stand → walk → run The difference between calibration and conditioning (and why most warm-ups are wasted) Reclaiming physical culture for everyone from kids in school to adults who have "given up" on regular movement practices A real-life example in Gray's assessment of Garrett's movement during their time together If you check a wearable every day to see your readiness and recovery, what are you doing to check your movement system? In this episode, you will learn a clear framework for running that same type of diagnostic on your musculoskeletal health. And underneath all of this is a deceptively simple principle. As Gray puts it, the sustainable path to health, fitness, and vitality is to "first move well, then move often."

    Ep 129: The Speech Therapist Who Lost Her Voice – and Rebuilt Her Practice on What She Learned

    Imagine being a speech therapist and waking up in an ICU, unable to speak, swallow, or move your head and neck. That's what happened to Vanessa Abraham, MS, CCC-SLP, seven years ago when she was paralyzed by the pharyngeal-cervical-brachial (PCB) variant of Guillain-Barre. In this episode, she shares the full story from ventilator, tracheostomy, G-tube, and eye gaze boards through her path to eventually rebuilding her voice, her ability to swallow, and her clinical practice.  We cover: The PCB variant of Guillain-Barre and what recovery actually looks like How Vanessa found the Neubie, which turned out to be the missing link in her recovery The ways she uses electrical stimulation on the head and neck in her speech-language pathology practice, and how she dials in for swallowing and vocal cord function Polyvagal theory, why the body can't heal in a state of fight-or-flight, and how Vanessa uses the Master Reset Her frameworks for working with children with autism, adults with neurodegenerative conditions, and people experiencing PICS (post-intensive care syndrome) Vanessa is now one of the first SLPs in the world using the Neubie and has become a passionate educator through her book Speechless, her various talks and appearances, and her clinical practice. Her story is a very powerful pain-to-purpose conversation.

    Ep 128: From Smelling Salts to Sensorimotor Testing: A Better Way to Treat Concussions

    When Dr. Ted Arkfeld started as a team chiropractor in the early 2000s, the standard sideline concussion test was a whiff of smelling salts and a question: "Feel okay? Get back in." Twenty-plus years later, he's built one of the most rigorous neurological assessments in the field, and is one of the only chiropractors in the country presenting concussion research alongside the world's foremost authorities. In this episode, he walks us through what changed, what's still broken, and a better way to treat concussions from the nervous system up. We cover: Why you cannot have a concussion without a cervical spine injury and why mainstream concussion medicine has been late to catch on The Neuro Sports Performance Evaluation that combines autonomic testing, sensorimotor function, and Neubie mapping The 3x increase in lower-extremity injury risk after a concussion and how to prevent it Why even gentle treatment can metabolically overwhelm a concussed brain and how a $20 pulse oximeter solves it The layered treatment protocol Dr. Arkfeld uses: Cox flexion-distraction, Master Reset, Normatec, BrainTap, and progressive neuro rehab If you treat athletes – or you're the parent of one – this conversation will change how you think about concussion management.

    Ep 127: The 490,000-Athlete Dataset Changing How We Train and Rehab

    In this episode of The Undercurrent Podcast, Garrett sits down with Dr. Trent Nessler, a physical therapist, biomechanics researcher, and founder of The Athlete Lab in Franklin, Tennessee. Over 28 years in practice, Trent has built one of the most comprehensive movement-data engines in the world: the ViMove+ AMI wearable sensor system, which has now captured over 4,700 data points per assessment on more than 490,000 athletes across five countries. What he's learned from that dataset is rewriting how we think about injury risk, ACL rehab, and return to play. In this conversation, we cover:                                  The profound role of pelvic stability and dynamic valgus speed in predicting ACL injury Fatigue-state training and why the ACL Play It Safe program works best after practice                                                                                    How Trent integrates NEUBIE, BFR, biologics, red light therapy, and nutrition into a truly holistic rehab model                                                         Lessons from assessing thousands of firefighters, police, and Special Operations personnel                                                       The role of mindset, hope, and a warrior ethos in recovering from catastrophic injury                                                                                       Whether you're a clinician, coach, athlete, or tactical operator, this conversation offers a rare look inside the mind of someone who has spent nearly three decades measuring, questioning, and refining what it actually takes to move – and heal – at the highest level.

    Ep 126: Stiff Hips, Slow Swing: The Missing Foundation in Your Golf Performance Pyramid

    Most golfers are chasing a better swing. But what if the real limitation isn't your technique, but your body? In this episode with Mike McDonnell, we break down the Golf Performance Pyramid and discuss why most players are building their game on an incomplete foundation. We cover: The Golf Performance Pyramid: mobility → stability → strength → power Why hip mobility (especially internal rotation) is a major limiter of speed and consistency How skipping foundational movement leads to compensation and injury The difference between training muscles vs training movement How to structure training year-round, including during competitive seasons If you want more distance, consistency, and longevity, don't just work on your swing … Fix the foundation it's built on.

    Ep 125: The Neurology of Movement: A Two-Way Street Between Brain and Biomechanics

    We often treat movement like a one-way equation: Brain → Body → Performance.  But in reality, it's a feedback loop. The body is constantly sending information back to the brain, and that information shapes how we move, perform, and recover.  In this conversation with Harry Worrow, we talk about his frameworks for working with everyone from athletes to individuals with neurodegenerative conditions, and how he uses biomechanical analysis paired with functional neurology. Specifically, we cover: The two-way relationship between neurology and biomechanics Why better sensory input leads to better movement output A deeper look at working with the visual and vestibular systems Why movement quality should come before load and intensity Strategies for long-term progression in neurodegenerative cases Movement is a blend of hardware and software, mechanics and neuroscience. Ultimately, it's shaped by how the nervous system interprets and responds to the world – and the good news is that this you can influence this process with the right techniques and strategies.

    Ep 124: The New Patient Pipeline: Breakthrough Strategies for Practice Growth

    What happens when physician referrals start disappearing? For Chad Madden, it forced a complete reinvention of how his practice attracted patients. That shift ultimately led to scaling his clinic to seven locations and co-founding Breakthrough to help hundreds of practices do the same. In this episode we discuss: The New Patient Pipeline and how it works The difference between clinician messaging and patient messaging Why direct response marketing works for healthcare The systems that turn cold leads into paying patients How cash-pay services are reshaping the economics of private practice The takeaway: Great care alone doesn't guarantee growth. You also need a system to create demand, and Chad shows us that system.
