ARX Adaptive-Resistance

Science-backed strength training that auto-adjusts to you. Maximize gains, minimize risk.
The ARX system pairs motorized resistance with real-time feedback, matching your exact strength curve on every inch of every rep. No guessing weights, no plateau-inducing momentum... just the precise stimulus your muscles need to grow stronger in minutes, not hours.
Why it matters
- Auto-adjusts every millisecond so you’re never over- or under-loaded
- Max results in less than 20 minutes: perfect for packed schedules
- Data you can see: instant force curves and strength scores after each set
- Safe for every body: low joint stress, ideal from rehab to elite performance
- One coach, one machine, zero wasted motion: the most efficient workout in St. Louis
Carol Bikes

AI-powered indoor cycling for a high-intensity, low-impact cardio blast.
CAROL’s REHIT-driven bike condenses an hour-long cardio workout into an 8-minute ride. Built-in AI learns your power output, then delivers two 20-second “all-out” sprints that spike oxygen uptake, torch calories, and stay gentle on joints, all while tracking every watt so you can watch your fitness climb.
Why riders love it
- 8 minutes, start to finish; perfect between meetings
- REHIT protocol boosts VO₂ max up to 12 % in 6 weeks
- Adaptive resistance personalizes every sprint automatically
- Low-impact cadence = joint-friendly for all ages performance
- Instant performance metrics keep you motivated ride after ride
Bulletproof Vibe Plates

Whole-body vibration to optimize bone health, flexibility, and core activation.
Whole-body vibration recruits deep stabilizer muscles and stimulates bone tissue with thousands of micro-contractions per minute. Just a few minutes on the Vibe Plate enhances warm-ups, accelerates recovery, and provides a low-impact way to boost mobility and joint health.
Why we use it
- Stronger bones – mechanical loading shown to improve mineral density
- Instant mobility boost– loosens tight hips, hamstrings, and back in 60 seconds
- Core activation – reflexive contractions fire up deep abdominal and spinal muscles
- Better circulation & lymph flow – speeds nutrient delivery and waste removal
- Perfect primer or cooldown – pairs seamlessly with ARX and CAROL sessions
Fit3D Body Scanner

Full-body 3D scan tracks your exact shape and posture improvements over time. Privately.
The Fit3D scanner creates a millimeter-precise 3-D avatar in under 40 seconds, capturing circumferences, body-fat %, lean-mass balance, and posture alignment all at once. Each visit overlays new data on your baseline, so you can see inch-loss, muscular symmetry, and postural corrections; proof your program is working.
What you get
- 50+ measurements: hips, waist, arms, lean vs. fat mass
- Posture & balance score: shoulder tilt, spinal alignment, weight distribution
- Progress overlays: color-coded changes mapped onto your avatar
- Low-impact cadence: PDFs sent instantly to your inbox
- Motivation multiplier: objective data keeps you focused between sessions
Sunlighten Infrared Sauna

Deep-heat therapy to speed recovery, detoxify, and boost circulation.
Bask in penetrating far-infrared heat that warms muscle and connective tissue from the inside out, raising core temperature without the stifling air of a traditional sauna. The gentle waves trigger a “passive cardio” effect that accelerates blood flow, stimulates natural detox pathways, and leaves you relaxed yet re-energized for whatever’s next.
Why it’s a BioFit essential
- Faster recovery – heat increases nutrient delivery to tired muscles
- Natural detox – sweat carries out heavy metals and everyday toxins
- Calorie burn – passive heart-rate bump mimics light aerobic work
- Joint relief – deep warmth eases stiffness and chronic aches
- Sleep upgrade – post-session drop in body temp promotes deeper rest
