Ep 137: Mind-Body Unity: Two Doors Into One System
The NeuFit Undercurrent Podcast
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...

Ep 136: Does It Turn the Muscle On, or Turn it Off? Muscle Activation and Testing Every Device
The NeuFit Undercurrent Podcast
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...

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

EP 134: All Things Achilles: Two Injuries, Two Roads Back, and How to Build Resilient Tendons
The NeuFit Undercurrent Podcast
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...

Ep 133: My Four Biggest Shifts at 40: The Ideas that Have Actually Changed How I Live
The NeuFit Undercurrent Podcast
Turning 40 inspired me to stop and reflect in a deeper way. In that reflection, I asked a question I hadn't asked in a while: which ideas have actually changed the way I live? Four rose above the rest (convenient since it was my 40th!), and one thing that surprised me is how they build on each other, almost like a manual for how to live. In this solo reflection, I walk through all four, along with the single thread that connects them: awareness/mindfulness comes before change, every time. Key insights include: Why alignment, not achievement, has been the biggest unlock for me, and ways to...

Ep 132: The Steering Wheel of Your Nervous System: Breathing, CO2 Tolerance, Healing & Longevity
The NeuFit Undercurrent Podcast
Dr. Sachin Patel believes the single most accessible, highest-leverage tool for our health has been right under our noses the whole time: the breath. In this episode, Garrett and Sachin go deep on why breathing is the "first domino" that knocks down a hundred others – influencing everything from our metabolism and circulation to the immune system and nervous system. If you've ever felt like your health routine is getting more complicated instead of simpler, this conversation is a powerful reminder that the most sophisticated answer is often the simplest one. We cover: Why breath is the...

Ep 131: Born to Run, or Born to Walk? Mark Sisson on the Movement Your Body Really Wants
The NeuFit Undercurrent Podcast
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,...

Ep 130: First Move Well, Then Move Often: Gray Cook on Functional Movement
The NeuFit Undercurrent Podcast
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...

Ep 129: The Speech Therapist Who Lost Her Voice – and Rebuilt Her Practice on What She Learned
The NeuFit Undercurrent Podcast
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,...

Ep 128: From Smelling Salts to Sensorimotor Testing: A Better Way to Treat Concussions
The NeuFit Undercurrent Podcast
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...
info_outlineAchilles 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.
