For medical professionals
The strength-protocol dose your patients complete.
ARX integrates into longevity, regenerative, weight-loss, hormone, and integrated-medical protocols as the dose-response strength arm. Two 15-minute sessions per week. Peer-reviewed.
Clinical fit by practice type
Longevity & age-management clinics
Executive longevity, functional medicine, age-management, concierge MD, corporate executive health
Executive longevity, functional medicine, age-management, concierge MD and corporate executive health. Adaptive resistance integrates as the strength-protocol arm of a longevity workup alongside VO2max, HRV and body composition tracking.
Weight-loss & metabolic clinics
GLP-1 weight loss
GLP-1 prescribers running structured strength protocols to preserve lean mass during pharmacological weight loss. ARX is the lowest-friction strength dose-response that patients on GLP-1 complete.
Hormone & menopause clinics
Men's health / TRT, women's HRT / menopause
Men's health / TRT and women's HRT / menopause clinics layering structured strength training onto hormone-replacement protocols for muscle and bone outcomes.
Regenerative medicine
Regenerative, sports medicine, integrative oncology
Regenerative, sports-medicine and integrative-oncology practices combining adaptive resistance with regenerative protocols (PRP, exosomes, stem-cell) for return-to-function.
Medical fitness & rehab
Hospital medical fitness, sports PT, post-rehab, chiropractic + exercise-Rx, geriatric / fall-prevention
Hospital-affiliated medical fitness centers, sports PT, post-rehab / return-to-play, chiropractic + exercise-Rx and geriatric / fall-prevention clinics. ARX as the strength-prescription dose.
Med-spa with body composition
Med-spa with body composition
Med spas adding body-composition services and strength protocols to extend per-patient revenue beyond aesthetic procedures.

Common questions from clinicians
What is the peer-reviewed evidence base for ARX?
The primary trial is Dalleck et al. (2021) in the International Journal of Research in Exercise Physiology, with validation commentary from the American Council on Exercise: 2.5× greater fat loss, 2× lean-mass gain, 3.5× VO2max improvement and 90% greater 1-RM strength change vs. traditional resistance training in 72% less session time over a 12-week RCT. Supporting literature includes Nuzzo 2023 (CARE framework, PMC10127187), Galiano 2024 (accentuated eccentric loading) and ongoing GLP-1 muscle-preservation analyses. Full timeline is published at science.arxfit.com.
How does ARX compare to traditional resistance training?
Adaptive resistance matches user-generated force throughout the full range of motion, including the eccentric phase where most strength + hypertrophy adaptation occurs. The Dalleck 2021 RCT measured superior body-composition, strength and VO2max outcomes in 72% less session time vs. an ACSM-guideline traditional comparison group. The mechanism is eccentric overload coupled with progressive intensity that's impossible to replicate with stack-loaded weights.
How does ARX fit a clinical protocol?
Two 15-minute supervised sessions per week reach the dose-response threshold for measurable strength + body-composition outcomes. Sessions integrate with biomarker capture (force-curve, time-under-tension, set-by-set strength logged digitally) so protocol adjustments are evidence-driven. Most clinical adopters bundle ARX into longevity, hormone-replacement or post-surgical care plans rather than running it as a standalone service.
Is ARX appropriate for GLP-1 patients?
Yes — increasingly required, not just appropriate. STEP-1 / SURMOUNT follow-up analyses (2025) show GLP-1-associated weight reduction includes substantial lean-mass loss, reinforcing the case for formal resistance-training referral. Adaptive resistance preserves lean mass during pharmacological weight loss when other modalities can't reach the dose-response threshold within the patient's available time. The GLP-1 cohort integration protocol is documented in the science hub.
What is the safety profile of adaptive resistance equipment?
Load follows user-generated force output and cannot exceed voluntary capability — the system can't push someone into a load they can't produce. Suitable for broad age ranges (Landi 2024 documents strength gains in oldest-old populations) and selected post-surgical / metabolic populations with physician clearance. Standard contraindications: acute injury, uncontrolled hypertension, active infection.
Can ARX integrate with our EMR or care-plan workflow?
Session data (force curves, time-under-tension, strength progression) is digitally logged and exportable. Most clinical sites integrate via SFTP delivery to the EMR vendor or manual progress-note entry from the dashboard summary. Dedicated EMR API integrations are available for enterprise deployments — covered in the discovery call.
What revenue model do clinics use?
Three patterns are common: (1) bundled into a longevity or hormone-replacement protocol fee ($300-800/mo per patient retention upsell tier), (2) standalone strength-protocol service line at clinic-set pricing, (3) clinical research collaboration with academic partners. GLP-1 weight-loss clinics typically reach equipment ROI at ~22 patients on the strength-line — full operator economics walked through in the paid demo.
What does installation involve?
Alpha is ~30 sq ft footprint; Omni is ~40 sq ft. Standard 110V power, no plumbing or special ventilation. Most clinics integrate without renovation. Installation, protocol training and the first 90 days of clinical-team support are included in the purchase.
Are there reference clinics we can speak with?
Yes — Tier-A reference installations across longevity, GLP-1 and post-surgical settings are available for site visits or virtual peer calls. Names + outcomes are shared after the paid demo so the ARX team can match a reference whose ICP and protocol style align with yours rather than a generic introduction.
