How New Fit’s “NEUBIE” Direct Current Device Transforms Rehab, Performance & Recovery | Garrett Interview

Pat Rigsby interviews Garrett, founder of New Fit (NEU for neurological + fit), about the NEUBIE (“neuro bioelectric”) direct current device and how prioritizing nervous system function can impact rehabilitation, chronic pain, fitness, and athletic performance. Garrett shares his background as a college hockey player and physics major whose injuries and frustration with traditional PT led him to functional neurology, direct current stimulation, and ultimately creating NEUBIE after years of clinical work in Austin and graduate study in neuroscience. They discuss NEUBIE’s “mapping” process to identify guarding, excess tension, inhibition, and hypersensitivity patterns, and how direct current can accelerate neuromuscular reeducation to quickly change function—highlighting examples like improved shoulder range of motion in a single session and the “master reset” vagus nerve stimulation-style protocol for recovery. Garrett explains New Fit’s growth to 400–500 U.S. clinics plus international distributors, mentions exposure through athletes like Saquon Barkley and discussions on Joe Rogan’s podcast, and outlines research including a 150-patient diabetic peripheral neuropathy study comparing TENS (AC) to NEUBIE (DC), showing significant improvements in pain, sensation, ADLs, EMG amplitude, and nerve conduction velocity with direct current. For gym owners and performance facilities—especially those serving older populations—Garrett covers applications for loading muscles with less joint strain, references bodybuilding use (including Dexter Jackson’s reported leg improvements leading to a 4th-place Mr. Olympia finish at age 50), and cites University of South Florida studies showing similar acute responses and 8-week muscle growth compared to traditional resistance training. They close with what’s next (more research, next-gen innovation, and exploring AI) and how providers or individuals can learn more via www.new.fit and the provider directory.
