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...

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

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

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

Ep 124: The New Patient Pipeline: Breakthrough Strategies for Practice Growth
The NeuFit Undercurrent Podcast
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 ...

Ep 123: From Managing Symptoms to Creating Solutions: Treatment Plans That Create Real Outcomes
The NeuFit Undercurrent Podcast
Most healthcare is built around managing symptoms. A little treatment here. A quick intervention there. “Let’s try this and see how you respond.” But what if the real problem isn’t the pain – it’s the system treating pain? In this episode, Dr. Mike Carberry and Colleen Carberry, PT, the founders of Advanced Medical Integration break down: Why symptom-based care keeps patients on the “train to drugs and surgery” How integrating physician care, chiropractic, and PT, compresses recovery time Why frequency and coordinated team care matter more than isolated visits How structured...
info_outlineModern pain care often focuses on fixing structures, but what if the real key is changing the signal? In this episode, Garrett and Dan Neff, DPT, dive into the idea of therapeutic input and how precise neurological stimulation can reduce pain, restore function, and build trust with patients – even the ones who’ve already tried everything else.
You’ll learn about:
- Neurological versus mechanical models of pain
- Why less force can sometimes produce better results
- How spinal input influences pain perception
- The nuanced differences between manipulation, adjustment, and neuromodulation
- Integrating Neubie for complex cases of neurological injury and degeneration
If you’re a clinician, practice owner, or someone struggling with persistent pain, this conversation offers an insightful perspective on what effective treatment really looks like
