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.

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." 

Healing is rarely about fixing a single tissue or structure. In this episode, Lisa Chase, PT, shares the frameworks from her new book, Be Responsible, Because the System Isn't, and describes why true recovery depends on the health of the entire system – from the nervous system and sleep to lifestyle, resilience, and capacity. When the whole system is robust, healing becomes possible. When it's not, symptoms simply move around.

In this conversation, we discuss:

• Why pain and injury are often downstream expressions of system overload
• How nervous system regulation shapes recovery, inflammation, and resilience
• The Pyramid of Healing and moving beyond symptom management
• What it means to rebuild health instead of chasing relief
• How tools like movement, lifestyle changes, and technology fit into a whole-system model

This episode is an invitation to rethink healing. It's not something that's done to you, nor is it something done in isolation. Rather, healing is something that emerges when the whole system is supported.

I'm joined today by my colleague at NeuFit, Clay Edgin. Clay has competed in over 80 strength competitions in 6 countries and coached powerlifting clients for nearly a decade. He discovered NeuFit as a client in preparation for the World Armlifting Championships, the world's premier grip strength competition, held annually in Russia. Listen in as Clay describes his experience using NeuFit for rehabilitation and what it's done for his own training, and why he believes it will enable him to compete in strength sports for many years to come.  

In this episode, we are visiting with Steve Capobianco, DC, the co-founder of RockTape. He shares his story of starting RockTape and the incredible education platform that they've built (certifying over 100,000 practitioners worldwide!). He also describes numerous concepts from pain science and the neuro-centric treatment methods that they teach in their curriculum. For our regular listeners, you will recognize a ton of overlap between their approach and ours and see that RockTape offers really valuable tools that complement our work at NeuFit.  

Today, I'm joined by my good friend Joe Distefano. In this episode, Joe talks about his experience recovering form a traumatic brain injury and how specific neurological treatments plus a shift in his mindset ended up making the biggest difference when his progress had stalled.

One of the themes you'll hear in this podcast is how Joe's brain injury served as an "indicator" for him. Because it was sensitive to changes in his environment, his condition showed him exactly when his lifestyle was helping or harming him. He was able to use these learning experiences to craft the interventions and tools he now shares with his business, Runga Life.

I'm joined today by NeuFit's new Director of Research Dr. Ramona von Leden, PhD. Dr. von Leden is spearheading several projects with us here at NeuFit that we're very excited to share with you.

Inspired by her own mother's spinal cord injury, Ramona dove head first into the topic of neuroscience to better understand how to help her mother recover. 

Enjoy!

I'm joined today by Dawn Nasta, a hypertrophy and rehabilitation specialist in the Phoenix area. Dawn's understanding of the nervous system has enabled her to not only get her clients out of pain faster than traditional therapies, but also enabled her to produce champion athletes in the extremely competitive arena of physique sports. She shares insights into how she's been able to help these athletes, including the incredible story of how she helped Ms. Fitness Olympia Whitney Jones avoid surgery and defend her title.    Listen in as Dawn describes how mastering the nervous system can unlock potential for everybody from novices to professional athletes.

I'm joined today by Brad Rowe, a professional bodybuilder and trainer to numerous professional athletes and celebrities. In this episode, Brad describes his experiences using the Neubie to help himself recover from various injuries (far ahead of schedule!) and optimize his own training. He then shares how he's used it to help some other incredible athletes. He talks about his work with Mike Tyson, who Brad trained daily for several months in preparation for Mike's comeback fight at age 54, as well as how he used the Neubie to help Dexter Jackson compete on the main Mr. Olympia stage at age 50. Plus, now that he's just retired from professional bodybuilding, Brad gives us a little glimpse into his next project.

I'm joined today by Samuel Buckner, PhD, a professor and researcher at the University of South Florida. In this episode, you will learn the fundamental elements of hypertrophy for strength and muscle growth, broken down to a cellular level.

Dr. Buckner is also conducting a no load / low load study on how the Neubie can induce hypertrophy. Tune in, learn, and share!

What happens when a child suddenly loses the ability to walk – and the answers aren't structural, surgical, or pharmaceutical? In this episode, Garrett sits down with George James and Katie, the mother of 9-year-old Jodie, to share an extraordinary and deeply human story of Functional Neurological Disorder (FND), resilience, and recovery. In this conversation, we explore:

• Jodie's sudden onset of FND after fainting during a field hockey game, and the loss of walking, speech, and confidence
• The emotional and logistical journey of navigating a misunderstood condition
• George's decision to travel from the UK to Kenya for a 5-day intensive
• The clinical framework for approaching FND, including an emphasis on sensory input, play, and nervous system retraining 
• Broader takeaways from this story and what it teaches us about neuroplasticity, graded exposure, "deconstructing" movement patterns like gait, and more

This story is an inspiring example of patience, trust, and the remarkable adaptability of the human nervous system, with some extremely valuable clinical insights mixed in.

Master Trainer and Rehab Specialist Jean-Paul Francouer of Little Rock, Arkansas knew from his extensive career that it often wasn't just the structural components, or hardware, of the body that were responsible for compensatory movement patterns and pain, but the nervous system, or software, that needed training.⁠
⁠
As he shares in this episode of The Undercurrent Podcast, that belief led him to electrical stimulation therapies and specifically direct current. Once he integrated the Neubie into his practice, not only was he able to retain clients for longer by moving them from rehab into fitness training, but he grew so busy that he hired someone to take on his burgeoning client load.

On this week's episode of The NeuFit Undercurrent podcast, I'm joined by seasoned rehabilitation expert Ed Patterson. Ed works in our Austin headquarters and has had a deeply diverse range of  experiences in the rehabilitation space.

As part of his practice, and performs mobile sessions for clients as well as in clinic sessions using the Neubie. Today we discuss some of the more interesting and challenging success stories he's been a part of as well as get an insight into how his work with the Neubie has enabled him to achieve those successes faster.

I'm joined today by Jameson Taillon, pitcher for the Pittsburgh Pirates. In this episode, Jamo recounts what led him to discover the Neubie and how it had a profound impact on his recovery, not to mention how he's been able to stay strong with minimal equipment and the Neubie while quarantining at home due to MLB facilities shutting down for Covid.

We're looking forward to seeing what Jameson does in the upcoming season!

Watch him work for just five minutes and you'll never look at these rehabilitation experience the same. I'm joined today by one of most sought-after in house rehabilitation specialists here at NeuFit HQ, Steve Haldemann.

A trainer and strength and conditioning coach all of his life, Steve was a competitive bodybuilder when he suffered a bad motorcycle accident. Using the Neubie technology and his tenacious attitude in the gym, he was not only able to come back but win his next bodybuilding show. Listen as he describes how his passion for helping people who have been told they have no hope combines with the technology and techniques employed at NeuFit to create amazing outcomes for very challenging situations.

In this episode, we dive into one of the most under-leveraged and over-used terms in business: your Core Values. How can you define what drives you and why does it matter? Is it enough to attract and motivate the right team? Listen in to learn more. 

Most practice owners don't get stuck because they lack tactics – they get stuck because they're still operating with a clinician's identity. In this episode, Garrett sits down with Jamey Schrier, DPT, to unpack why sustainable growth and practice value require a fundamental shift in how owners see themselves and their role. In this conversation, we cover:

• Why clinical excellence alone doesn't build a valuable business
• The identity shift from clinician to true practice owner
• Common traps that keep owners stuck in the day-to-day
• What actually makes a practice "sale-ready"
• How systems and leadership replace owner dependency

This episode is a must-listen for anyone who wants their practice to create freedom instead of just more responsibility.

In this episode of The NeuFit Undercurrent, I talk with Dr. Lauren Leiva, DPT of The Exerscience Center in Lutz, Florida about how she used her own resilience and mindset to not only heal herself, but also create a thriving integrative physical therapy practice to make massive changes to her patient's lives.

Lauren details her struggles with Crohn's and a pregnancy that left her hospitalized for 9 months that would have caused most people to throw in the towel and relegate themselves to a life of "less than." Not only was she able to get back to a baseline of health, she's been able to take her own progress past any other conceived limitations.

In this episode of The NeuFit Undercurrent podcast, Garrett explains the importance of the role of the autonomic nervous system and how resilience plays a major factor into your nervous system health.

On this episode of The NeuFit Undercurrent, Garrett expounds on a topic we get asked about a lot regarding how we use a neurological approach to rehabilitation and fitness. How are they different? How are they the same? 

Husband and wife team David Harris, MD and Michele Zink Harris, PT, own and operate CHARM Austin - a regenerative medicine facility among the first of its kind to incorporate physical therapy and regenerative medicine. 

In this episode, Michele recounts some of the more amazing outcomes she's been able to have with this neurological approach to physical therapy and how it's made even more powerful by her husband's team of regenerative medicine specialists.

Joe & Angie McGilvrey's physical therapy office Apex Physical Therapy in Fort Myers, Florida has quickly become one of the top performing offices for positive outcomes. They way they use the Neubie from early stage rehabilitation to elite athletic performance is a shining example of their creativity, passion, and holistic approach to wellness. 

I'm joined today by Angie and Jason Wyns, who runs the sports performance side of the facility. Listen in as they describe how they set themselves apart from the competition by not only utilizing cutting edge technology but also "walking the walk" themselves. 

Joining me today is Jason Waz, PT a physical therapist in Tampa who used the Neubie to scale his business at a rate he never thought possible. Jason is also our Director of Physical Therapy and acts as a resource to potential Neubie customers on how to integrate and optimize the use of this technology for their business.

In my first virtual podcast, I meet with Dr. David Woodward, DPT of Na'au Pono Physical Therapy in Honolulu, Hawaii. 

I first met David at a biohacking conference years ago where, during a stunt you'll have to hear to believe, he and his wife both injured themselves. But if you're going to heal, adapt, and grow faster than you ever thought possible, what better place than in a room full of biohackers?

Listen in as David talks about how the Neubie moved the needle for him in his and his wife's own recovery, how he came to purchase a Neubie for his own practice, and the amazing outcomes he's received from it so far.

I'm joined today by Lance Winn. A lifelong athlete and veteran of the armed forces, Lance suffered a sudden and surprising paralysis after back surgery. Listen to how his indominable will kept him looking for the best technology and brightest minds to help him heal, adapt, and grow.

In addition to his personal story, Lance is also on the board of the Lone Star Paralysis Foundation. This wonderful organization sponsors leading-edge research and treatment for spinal cord injury, and Lance shares some insight into LSPF as well as how they have incorporated NeuFit into all of the advanced treatments that they do at their flagship clinic here in Austin, TX. 

In this very special episode, I share with you a presentation I gave at the Dr. Terry Wahls Virtual Summit on neuroplasticity. In it, I discuss many of the available rehabilitation modalities being used for neurological diseases like multiple sclerosis and share a compelling story about how one of our clients went from a wheelchair to being behind the wheel of her car again. Even dancing!

Throughout our business, we are introduced to incredibly innovative, forward-thinking professionals on all places of the rehabilitation and fitness spectrum. My guest today on the NeuFit Underground podcast is Dom Pelosi, an elite trainer and bodywork specialist out of Gilbert, Arizona who has successfully incorporated the Neubie into his business for highest level of athlete in the southwestern states.

In this episode, Dom talks about how he was stuck in his career and considered a change, but after incorporating the Neubie into his business, he's been able to achieve success he never dreamed possible. Make sure you follow Dom @the_phyzeeksmith to follow his journey!

Modern 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

I'm very excited to talk with Dr. Dave Heitmann, DC. Dave is a former rugby player, self proclaimed "strength geek" and our Medical Director here at NeuFit headquarters. In this episode, Dr. Dave explains how the Neubie is the perfect compliment for any chiropractor's office and how it leads to scalability and profitability quicker than anything else on the market. 

Dr. Dave's approach to his practice has been to add just "a little bit of juice" to aid in the body's natural propensity to heal through an input-based approach to rehabilitation. It was that common thread that united us and we're so fortunate to have him on our team.

This week, I sit down with Laura Davis, PT, DPT, as we discuss some of her favorite success stories when she took a neurological approach to rehabilitation for her patients. 

Dr. Davis is a physical therapist in our Austin headquarters and also does telehealth appointments for patients who have the Neubie, our direct current stimulation device that we use to impart massive neuromuscular reeducation. 

I'm joined today by Amy Johnson, who suffered a spinal cord injury nearly 30 years ago. In this episode, we talk about how the NeuFit Method and the Neubie have helped her regain strength in her legs and get her walking for the first time! 

Thank you so much for joining me on this, the first episode of The NeuFit Undercurrent Podcast. In it, I'll give you some background information on how I became obsessed with healing the body through treating the nervous system and get a glimpse into some of the amazing things you'll see on the show. Let's do this!

Most practice owners start with purpose but get lost in the chaos of growth. In this episode, Garrett sits down with Will Humphreys, PT, and Michelle Bambanek, PT, to explore how leaders can build scalable systems without sacrificing heart, humanity, or culture. Together, they break down the frameworks that help teams thrive as the business grows. You'll learn about:

• The leadership principles that create both profitability and purpose
• How to design culture intentionally, not as an afterthought
• Using frameworks like "Six Working Geniuses" for hiring, communication, and delegation in ways that sustain growth
• Common traps that erode trust as teams expand
• Why scaling "with soul" leads to stronger, freer organizations

This conversation is a roadmap for every owner who wants to grow without losing what made their mission meaningful in the first place.

What happens when physical therapy embraces the tools of diagnostic medicine? In this episode, Garrett talks with Drs. Skye Grayson, Malachi Votaw, and Julia Whitehead from NCEPT (Escondido, California) about how they've built one of the most advanced PT practices in the country by combining EMG, ultrasound, and Neubie neuromuscular reeducation.

You'll learn about:

• How objective diagnostics uncover what's really driving movement limitations
• The difference between structural and neurological dysfunction – and why it matters
• How Neubie integration accelerates nerve recovery and neuromuscular control
• Building a hybrid model that blends insurance-based care with cash-based innovation
• NCEPT's team-driven approach to leadership, mentorship, and excellence

This is a look inside the next evolution of physical therapy, where you'll see a clear and inspiring picture of how technology and teamwork converge to create better outcomes and stronger practices.

True athletic performance isn't built on muscle alone – it's driven by the nervous system. In this episode, Garrett explores how approaching training through a neurological lens can optimize movement, strength, and resilience across an athlete's lifetime. From youth development to elite performance, he breaks down how to train smarter, not just harder.

In this episode, you'll learn:

• How the nervous system governs strength, coordination, and recovery
• The "Pyramid of Performance" framework from The NeuFit Method
• Why early movement diversity builds long-term athletic capacity
• How End Range Activation (ERA) improves mobility and joint control
• The importance of relaxation speed and eccentric strength for power
• How NeuFit technology enhances neuromuscular re-education and resilience

Athletic development isn't a sprint, it's a neurological journey. And if you want to help yourself or your athletes reach their full potential, this episode will show you how incorporating neuroscience changes the game.

The quality of our relationships determines the quality of our life. And, although many of us know how to lead at work, we struggle to bring that same clarity, purpose, and intention into our homes and our most important relationships. 

In this episode, men's health and leadership coach Joel Evan shares how the same principles that drive success in business can transform relationships, communication, and connection at home. We cover several topics from Joel's book, Limitless: Forge an Unshakeable Marriage and Deepen Your Bond with Your Kids:

• How to apply leadership frameworks to marriage and fatherhood
• The power of extreme ownership in family life
• Why communication is the cornerstone of trust and intimacy
• Overcoming limiting beliefs that block authentic connection
• Building a legacy that lasts through your actions, not just your words

Whether you're a husband, father, or simply someone seeking to deepen relationships with more integrity and purpose, this episode will challenge you to show up where it matters most.

Low back pain is one of the most common – and complex – challenges in healthcare. In this episode, physical therapist Jeff Vitale shares how he applies Dr. Stuart McGill's evidence-based methods to help even the most difficult cases. Part of an elite group personally certified by Dr. McGill, Jeff integrates the McGill Method with other frameworks such as TPI and tools like the Neubie to create breakthrough results for patients who've often tried everything else.

In this conversation, we discuss:

• Jeff's personal story with back pain and surgery as a college athlete
• The philosophy and principles behind the McGill Method for detailed assessment, which includes redefining "chronic" back pain
• How detailed assessment identifies pain triggers and guides precise exercise programming
• Balancing stability and mobility in athletic movements like the golf swing
• Where the Neubie fits into the rehab and performance equation

This is an episode for anyone serious about solving back pain at its source. Whether you're a clinician looking for new tools or someone personally battling low back pain, this episode provides a roadmap with practical solutions.

Carbon-60 (C-60) is a molecule that won a Nobel Prize in Chemistry for its groundbreaking discovery – and now it's at the center of fascinating research into aging and longevity. In this episode, our guest is Chris Burres and we dig into the story of how a lab material used in industry found its way into the world of health and human performance.

In this episode, you'll hear about:

• The fascinating history of C60
• Why oxidative stress is central to aging and disease
• How C60 may act as a unique antioxidant without blunting exercise benefits
• Early animal studies describing C60's effects on lifespan, tumors, and inflammation
• Anecdotal reports in humans on sleep, recovery, inflammation, and HRV
• The importance of safety, purity, and scientific rigor in supplementation

Longevity breakthroughs always come with both promise and skepticism. This conversation brings the science, the story, and the open questions to light, so you can better understand where C60 fits in the longevity landscape.

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.

In this solo episode, Garrett dives into the powerful lessons that come from contemplating our own mortality. While it's often uncomfortable to think about, facing the reality that our time is limited can be one of the most practical ways to gain clarity about what truly matters – both in life and in business. The conversation includes:

• Reflecting on our own death as a powerful teacher
• The importance of having a true core purpose independent of external circumstances
• Why directing our energy wisely is the most important decision we make each day
• How "compressing time" exercises can cut through clutter and reveal real priorities

This is an invitation to pause, reflect, and reorient. By compressing time and confronting our own finiteness, we discover focus, alignment, and a clearer path toward leading our best lives.

What if your brain held the keys to living longer and healthier? In this solo episode, I dive into the fascinating intersection of neuroscience and longevity, unpacking how the nervous system shapes resilience, recovery, and the aging process. Drawing on both science and personal experience, I'll explore how practices like meditation, nervous system training, and targeted stimulation can help us unlock more years and better years. 

We'll cover:

• Why the autonomic nervous system is the hidden regulator of health and longevity
• How neuroplasticity impacts the body and mind
• The ways foot stimulation impacts the brain to reduce fall risk and extend independence
• What psychoneuroimmunology teaches us about stress, inflammation, and the immune system's role in aging, or "inflammaging" 
• Insights from meditation, HRV tracking, and direct experience of rewiring the nervous system for resilience

This is more than a discussion about just living longer, it's about living better too. Join me as we uncover how neuroscience provides both the framework and the tools to train your brain and body for vibrant health and longevity.

In this episode, we explore how neuroscience reveals what truly makes leaders effective – from how they regulate themselves, lead by example, and the various ways they can influence others and shape a team's culture. You'll learn how emotional safety, trust, and meaning aren't just soft skills but are actually brain-based performance drivers.

• Discover how a leader's role modeling combined with mirror neurons influence your team's mood, energy, and behavior
• Understand why brains in "threat mode" shut down trust, learning, and creativity and why psychological safety is the #1 predictor of high-performing teams
• Learn how to move from individual contributor to team multiplier
• Hear why storytelling activates more of the brain than data – and how to use that as a leader
• Explore how trust, purpose, and vulnerability unlock team engagement

Leadership isn't about control, it's about connection of people with each other and with a sense of shared purpose. And when you lead with safety, clarity, and purpose, you do far more than just manage a team – you multiply its impact.
