Garrett Salpeter - The NeuFit Framework: Nervous System First, Tissue Second

In this episode, Eric Malzone sits down with Garrett Salpeter, founder of NeuFit and creator of the NEUBIE direct current device, to unpack how targeting the nervous system can dramatically speed up recovery, reduce chronic pain, and unlock higher levels of performance across rehab, fitness, and even neurodegenerative conditions. ​ 🧠 Key takeaways 💥 Your nervous system is the "software" running your body's "hardware" (muscles, joints, tissues), and most rehab focuses on hardware while ignoring the software that actually controls healing and performance. ​ ⚡ Direct current (NEUBIE) works with the body's natural signaling pathways and can rapidly "turn on" inhibited muscles, improve movement quality, and often cut recovery timelines by 10–60% compared to traditional norms. ​ 🏃‍♂️ From Achilles tears and ACL reconstruction to chronic back pain, neuropathy, MS, and spinal cord injuries, NeuFit's method shows consistent results by reprogramming protective guarding patterns in the nervous system. ​ 🏋️‍♀️ For gyms and performance centers, NEUBIE becomes a powerful tool to keep clients training through injuries, accelerate mobility and hypertrophy, and support the growing "health optimization + longevity" model of training. ​ 📈 A head‑to‑head human study on diabetic neuropathy showed direct current improving nerve conduction, sensation, and function, while traditional TENS mainly offered temporary pain relief with little functional change. ​ Episode overview Eric opens by sharing his own experience using NEUBIE on a lingering Achilles issue that traditional methods couldn't fix, and how one intense session left him sore but noticeably better within a week or two. Garrett then traces his journey from disappointed hockey player and engineering student to building a medical device company around direct current and neuroscience-informed rehab. ​ He explains why NeuFit is spelled "NEU" (for neurological) and why he believes neurological fitness is the real upstream driver of faster injury recovery, metabolic and hormonal health, and long-term high performance. Instead of obsessing over damaged tissues on imaging, his approach starts with how the nervous system is reacting—guarding, bracing, shutting down, or misdirecting load. LINKS: ​
