The FRNOS System
Your Fascia Isn't Broken. It's Listening.
Every twist, load, and asymmetric demand you place on your body sends a signal your fascia is built to answer — remodeling, adapting, getting smarter with every session. RYNG Health's FRNOS (Fascial Remodeling Neuromuscular Optimization System) doesn't chase old myths about "releasing" tissue by hand; it engineers the mechanical conditions your nervous system actually responds to. This is fascia science, not fascia folklore — built for people who want results they can defend, not just feel.
The Cost of the Status Quo
Musculoskeletal disorders are the largest preventable line item in workers'-comp
Musculoskeletal disorders (MSDs) — sprains, strains, repetitive-motion and overexertion injuries — remain the single largest driver of workplace injury cost in the United States, estimated at $176.5 billion per year (National Safety Council, 2023). Most incumbent interventions — ergonomic redesign, PPE, stretch-and-flex programs — address posture and load, but not the underlying neuromuscular control that keeps a worker's tendons, joints, and reflex pathways resilient in the first place. Safety programs built only on strength and posture are treating a control-system problem with a hardware fix.
- Repetitive strain and overexertion drive a disproportionate share of claims across manufacturing, healthcare, logistics, and construction
- Traditional strength training builds muscle mass without necessarily improving neuromuscular efficiency or reactive control
- Workers'-comp EMR (experience modification rate) is directly exposed to MSD claim frequency and severity, making prevention a balance-sheet issue, not just a compliance one
A Different Model of Prevention
The body moves as a nervous system. Train accordingly.
Neurology leads. Hypertrophy follows.
RYNG's core position is that neuromuscular efficiency — force produced per motor unit recruited — is a better predictor of injury resilience than muscle size alone. Established research on motor-unit recruitment (Enoka & Duchateau, 2017), motor learning (Sanes & Lichtman, 2001), proprioception (Proske & Gandevia, 2012), and tendon mechanobiology (Maganaris, 2017) all point the same direction: durable, injury-resistant movement is built at the level of the nervous system, tendon, and joint receptor — not the muscle belly. The RYNG ring's circular geometry is the mechanical expression of that idea. Where a barbell, cable, or band delivers resistance along a single fixed plane, the ring's 360-degree profile invites continuous multi-planar stabilization — engaging the neuromuscular junction, tendon mechanoreceptors, and proprioceptive feedback loops in a way linear equipment structurally cannot.
- Engages the neuromuscular junction (NMJ) — where nerve signal becomes muscle force
- Loads tendon mechanoreceptors and Golgi tendon organs, which govern force regulation and protective reflexes
- Trains proprioception and joint-position sense, foundational to controlled movement under fatigue or awkward load (Lephart, 2000)
- Builds reactive neuromuscular control — the split-second stabilization after an unexpected slip, twist, or catch (Cook, 2010)
The RYNG Framework
A five-level training hierarchy
Each level draws on peer-reviewed motor-control and tendon-biology literature. RYNG's contribution is a single device engineered to progress a worker through all five in a structured program. (These citations describe general physiology, not RYNG-specific clinical trials.)
01 — Motor Unit Recruitment
Efficient activation of motor units before intensity increases — the foundation of neuromuscular efficiency (Enoka & Duchateau, 2017).
02 — Proprioceptive Calibration
Refining joint-position sense and body awareness in space, the sensory layer beneath safe, controlled movement (Proske & Gandevia, 2012).
03 — Tendon Loading & Remodeling
Progressive tendon loading to support connective-tissue resilience over time (Maganaris, 2017).
04 — Kinetic Chain Integration
Coordinating force transfer across joints and segments rather than isolating single muscles — matching how injuries actually happen across a linked system.
05 — Reactive Neuromuscular Control
Training the reflexive stabilization response for the unplanned moment — a slip, a sudden load, an awkward catch — where most real-world injuries occur (Cook, 2010).
The Workplace Program
One device. Three tiers of protection.
RYNG's enterprise platform delivers the ring alongside a branded, tenant-specific portal with regimens built around each client's workforce — mapped to a three-tier model that spans the full injury lifecycle, from prevention through return-to-work.
Tier 1 — Prevention
A daily 20–30 minute program for the entire workforce, designed to build baseline neuromuscular resilience before an injury ever occurs.
Tier 2 — Early Intervention
Targeted regimens for workers flagged as at-risk by role, ergonomic exposure, or reported discomfort — aimed at intercepting an MSD before it becomes a claim.
Tier 3 — Return-to-Work
Structured post-injury reconditioning to rebuild neuromuscular control and confidence before a worker resumes full duty, supporting safer, more durable returns.
Built for the Floor, the Line, and the Desk
Industries we serve
Each tenant portal is configured with position-specific modules — from a warehouse picker to an OR nurse to a long-haul driver — rather than a one-size-fits-all fitness routine.
Healthcare & Long-Term Care
Patient handling, prolonged standing, and repetitive-motion exposure for nurses, aides, and support staff.
Manufacturing & Assembly
Repetitive-motion and overexertion risk on the line, where MSD claims concentrate disproportionately.
Construction & Trades
Load-bearing, awkward-posture, and reactive-stabilization demands specific to job-site work.
Logistics & Warehousing
Lifting, reaching, and sustained physical throughput across shifts, where fatigue compounds injury risk.
Office & Knowledge Work
Sedentary-posture and repetitive-strain exposure for desk teams, positioned as a lower-intensity Tier 1 offering.

For Payers & Carriers
A device in the digital MSK care continuum
RYNG is positioned to sit alongside telehealth and remote-rehab platforms as a component of musculoskeletal care — comparable in category to digital MSK players such as Hinge Health, Kaia Health, and Sword Health, with the ring serving as the physical training modality inside a broader remote-care pathway. Client modeling projects $7–18 billion in aggregate payer savings over three years and a 3.5–8× return on program investment. These are projections for evaluation purposes, not realized results, and should be assessed against a payer's own population data.
- Designed to integrate with telehealth and remote-rehab care pathways rather than stand alone
- Positioned within the same category as established digital MSK care companies
- Payer-savings and ROI figures are three-year, client-modeled projections — not audited outcomes
Beyond the Workplace
A tool for focus, motor learning, and mastery
Some enterprise and community partners have expressed interest in RYNG as a hands-on tool that engages focus, repetition, and motor mastery — including for neurodivergent individuals. RYNG makes no medical, diagnostic, or treatment claims for autism or any other condition, and is not a substitute for professional care. Where offered, this use case is framed strictly as a structured motor-engagement activity, and any deployment in a clinical or educational setting should be directed by the qualified professionals on that team.
- Positioned as a focus-and-mastery engagement tool — not a medical, behavioral, or therapeutic treatment
- No diagnostic, therapeutic, or treatment claims are made for autism or any other condition
- Any use in clinical, educational, or therapeutic settings should be directed by qualified professionals
Research Alignment
Grounded in neuromotor science
RYNG's training framework draws on established, peer-reviewed research in motor control and tendon biology — including work by Enoka & Duchateau (2017), Sanes & Lichtman (2001), Proske & Gandevia (2012), Scott (2015), Maganaris (2017), Lephart (2000), and Cook (2010). RYNG's research agenda is aligned with the broader goals of neuroscience efforts such as the NIH BRAIN Initiative, and the company is actively pursuing research collaborations with academic motor-control and biomechanics programs. These are stated as research alignment and active pursuit — not as completed partnerships, endorsements, funding relationships, or government validation.
- Framework built on peer-reviewed literature in motor control, proprioception, and tendon biology
- Research agenda thematically aligned with the goals of the NIH BRAIN Initiative (no funding or endorsement relationship)
- Actively pursuing academic research collaborations as part of ongoing Series A growth
