    Ep 141: When Insurance Runs Out but the Diagnosis Doesn't: Long-Term Neuro Recovery at Adapt

    For people living with ALS, MS, cerebral palsy, or a spinal cord injury, the diagnosis doesn't end when the physical therapy benefits do. The real question is what comes next. Troy Baker, co-founder and Chief Program Officer of Adapt Functional Movement Center in Carlsbad, California, has spent more than a decade answering it. Adapt is a nonprofit built around long-term recovery, working with the whole person -- mind, body, and community. In this episode, we get into: Why Adapt chose a nonprofit model, and what that lets them focus on The developmental movement sequence behind every plan of care Why every session starts by assessing which version of the individual showed up today Reading the nervous system first: when to calm it down, when to wake it up A few examples, including how Troy uses the Neubie for MS-related drop foot and keeps a manual wheelchair user's shoulders healthy The answer to that gap, of course, isn't a single device or protocol. It's a system built for the long haul, where tools like the Neubie amplify work that is already well designed. Find Troy and the Adapt team at adaptmovement.org and @adaptmovement.

    Ep 140: When the Hardware Is Fine: A PT's Own Fight with PPPD, Dizziness, and a Brain Stuck in Threat

    One day after finishing a half Ironman, Karan Singh, PT, DPT, had his first panic attack. A week later, standing in the TSA line at the Austin airport, his vision started jumping and the ground began moving up and down. What followed was five months, seven-plus clinicians, a brain MRI, and roughly a hundred blood tests, all of them negative. The answer turned out to be persistent postural-perceptual dizziness, a diagnosis only solidified in 2017, and one most clinicians have already seen without recognizing it. The hardware was fine, it's the software was stuck. In this episode, we get into: What PPPD actually is, and the three criteria that identify it Why a brain stuck in threat abandons balance input and over-relies on the eyes The three phases of the protocol Karan built for himself with the Neubie Why exposure work land faster when you first down-regulate the neurological perception of threat The one instruction that matters most: do not let patients avoid the triggers If you have a patient whose dizziness never resolved and whose scans all came back clean, this episode gives you a name for it and a way in. And if that patient is you, Karan's own words are the place to start: it is functional, not structural, and it can be retrained.

    Ep 139: Who's Actually Running the Show: Hypnotherapy, Breathwork, and Why Willpower Keeps Losing

    You set the goal, built the morning routine, and brought the discipline. Yet somehow you ended up right back where you started.  Hypnotherapist and Master NLP Practitioner Aaron James Yager has a simple explanation: the part of you making the decision is not the part running the show. The subconscious manages the body and the behavior, and its first job is keeping you safe, which means it treats anything unfamiliar as a threat -- including the life you say you want. In this episode, we get into: Why willpower keeps losing to the subconscious, and where that programming comes from What hypnotherapy actually is, as distinct from the version you have seen on a stage The parallel between an inhibited muscle that will not fire and a belief that will not shift, and why speaking affirmations in the mirror so often do nothing Combining the Neubie, breathwork and hypnotherapy in a single session to promote the neurological perception of safety  How to up-regulate or down-regulate in under fifteen breaths At NeuFit, we're often working on the nervous system from the outside in, through direct electrical input. Aaron works on it from the inside out, through breath, hypnosis, and language. Both run into the same wall: you cannot reason a nervous system out of a state it believes is keeping you alive. And what this conversation is really about is the way through – change the state first, and the content work starts to stick.

    Ep 138: Don't Wait Six Weeks: Prehab, Post-Op Rehab, and Return to Sport

    Two people have the same ACL reconstruction, from the same surgeon, on the same day. One is back at 7 months, and the other is still working on it at 13. The surgery was identical, so what actually accounts for the difference? In this episode, Garrett sits down with Julia Grace Gillen, PT, DPT, better known as JG the PT, who runs a sports physical therapy practice in Jackson, Wyoming. In a town where people's identity is tied to being able to ski, run, climb, and get outside, the pressure to return someone to sport is different, and so is the standard. JG walks through the entire arc of post-op care, from the weeks before surgery through the day someone clicks back into their skis, and makes a very clear case that some of the most important work happens in the windows most patients are told to sit still through. In this episode, we get into: Why muscles begin to atrophy in about two weeks, and what effective prehab does for an outcome months later Why rehab should start within 24 to 48 hours after surgery, and what that first session actually looks like – even with restrictions from the surgeon The middle phase of rehab, where recovery is quietly won or lost, and the specific targets JG uses to get patients through it Why range of motion and strength have to be built in parallel rather than one after the other The piece missing from most return-to-sport programs, and why sixty seconds of side-to-side testing says nothing about a six-hour day on the mountain What runners consistently neglect: the foot, the big toe, and the soleus, and why a jump rope may be the most underrated training tool Whether you are a clinician building post-op protocols, an athlete staring down a surgery date, or someone who has been told to wait six weeks and do nothing, this conversation lays out what the research and a decade of mountain-town practice say about how recovery actually gets faster.

    Ep 137: Mind-Body Unity: Two Doors Into One System

    I have been fascinated by the relationship between mind and body for years. Of course, calling it a relationship implies two separate things. In this solo episode, I make the case that they are one system. The same playbook that took a football player's shoulder from 45 degrees to fully overhead in minutes (without ever touching the injured ligament), is the playbook it runs in psychology and behavior – limiting output based on the perception of threat and safety.  Key insights include:  Why guarding, inhibition and pain are protective outputs rather than failures, and why the same three show up in psychology as walls, withholding, and avoidance. The compensatory behaviors most of us carry, including examples like hyper-achievement, putting on the happy face, people-pleasing and the need for control, and what each one is actually protecting against. Why you cannot force a release in either system, and why every one of these patterns had a positive intention at the time it formed. The second door: research on entering the system through the mind, including Ellen Langer's famous studies like Counterclockwise and the Chambermaid Study.  Attention to variability, and how asking a chronic pain patient when their pain is better can loosen the label and restore a sense of agency. Most of what we call resistance, whether it's in a shoulder or in a life, is not stubbornness. It is a pattern of protection that has outlived its usefulness. And this episode is about how to tell the difference and what actually helps it let go.

    Ep 136: Does It Turn the Muscle On, or Turn it Off? Muscle Activation and Testing Every Device

    Most clinics choose their equipment based on what the research says, what the rep promises, or what everyone else is using. Chad Sirratt does something simpler and considerably more revealing: he tests the patient before and after, and asks one question. Did that device turn the muscle on, or turn it off? In this episode, Garrett sits down with Chad, owner of Texas Muscle Activation in Frisco, Texas, for a conversation about muscle activation, the whole-body detective work of finding out why something hurts, and what Chad learned when he started putting his patients' own recovery devices to the test. Along the way Chad walks through the layered treatment model he has built -- one of the most compelling and intentional sequences Garrett has seen in any clinic -- and explains why so many of the things we do to feel better may be quietly making us weaker. In this episode, we get into: What Muscle Activation Techniques actually is Why your hamstrings are tight, why stretching them is usually the wrong answer, and what the tightness is actually doing The whole-body assessment: why a flat foot can end up as neck pain, and why Chad reads the hip, foot, spine, shoulder, and neck as one system What a muscle test is really asking: not how strong is this muscle, but can it contract at all Why stretching, foam rolling, trigger point work, cupping, and dry needling can all leave a muscle testing weaker, and what that means for your recovery routine The device test: what happened when Chad put an athlete's popular stim unit on his arm and found inhibition running all the way down to his foot -- and what happened when he ran the same test with the Neubie The mistake Chad's clinic was making before decompression sessions, and how understanding current changed their entire protocol How MAT, the Neubie, and IsoPhit stack together to build stability the nervous system will actually trust Chad's one-line rule for what earns a place in his clinic Whether you are a clinician deciding what belongs in your practice, an athlete wondering why your recovery tools are not working, or someone who has been stretching the same tight muscle for years without lasting change, this conversation offers a different way to evaluate what is helping you and what is holding you back.

    Ep 135: The Long Game: Two-Way Prospect Noah Franco on the Road to MLB Draft

    In this episode, Garrett sits down with Noah Franco -- a 6'3", 240-pound two-way player at TCU and one of baseball's most intriguing prospects -- for an unusually candid conversation about the road that got him here and where he is headed. Noah walks through his California-to-IMG-to-TCU path, explains the MLB draft rules that most baseball fans do not understand, and gets into the daily discipline behind training as both a pitcher and a hitter at the highest level of college baseball. In this episode, we get into: Why leaving home for IMG Academy at fourteen was the first time Noah "banked on himself," and how that single decision reshaped his career trajectory The draft rule most fans do not know: why signing with a four-year college takes you off the draft board until after your junior year, and how NIL is changing the math for the next generation Choosing TCU over real pro money out of high school, and trusting the moment to develop rather than cash in early Two-way life at TCU: pitching AND hitting, how the coaching staff builds his weekly workload, and how Shohei Ohtani has opened the door for players like Noah at every level The physical transformation from 189 pounds to 240 pounds, and the shift from focusing on raw strength to new areas like lateral stability and rotational efficiency What we worked on in the clinic: thoracic mobility, teaching the nervous system to safely occupy new range of motion, and rebuilding the eccentric "breaking force" behind a healthy pitching follow-through The mindset that keeps Noah moving forward through pressure and outside noise Whether you follow baseball, work with elite athletes, or just want to understand how the best young players actually make decisions and train their bodies, this conversation is a rare inside look at what it takes to bet on yourself and play the long game.

    EP 134: All Things Achilles: Two Injuries, Two Roads Back, and How to Build Resilient Tendons

    Achilles injuries seem to be everywhere right now, from the NBA and NFL to weekend warriors. In this episode, Garrett sits down with physical therapist Luke Brohm, PT, DPT, OCS, for some big updates on our understanding of the Achilles tendon in 2026. It is a uniquely personal one, too: Luke is four months out from surgery to repair a full rupture, while Garrett is working back from a partial tear that became a stubborn tendinopathy. Together they compare notes on why these injuries happened, what actually drives recovery, and how anyone can build more resilient tendons for the long haul. In this episode, we get into: Why Achilles injuries appear to be rising, and what contributes to the "perfect storm" of under-recovery paired with spikes in load The load-vs-capacity framework that explains almost every injury, and why both of us were under-recovered the day we got hurt Luke's phase-by-phase comeback from Achilles surgery, from cast and isometrics to reintroducing plyometrics at four months Garrett's non-surgical tendinopathy journey: isometrics, resistance training, the Neubie, and the surprising setback culprit of the golf swing Modern tendon science: why "little and often" beats "long and hard," and how collagen plus vitamin C before loading feeds the repair Where the Neubie fits in tendon rehab: fighting atrophy, reducing inhibition, and restoring the neuromuscular connection The three biggest mistakes in recovery, and a prevention blueprint rooted in how our hunter-gatherer bodies are actually built to move Whether you are rehabbing an Achilles right now, working with patients who are, or simply want to stay explosive and injury-free for decades to come, this conversation will change how you think about tendon health.
