The real problem
Most people don't need more workouts — they need a better stimulus
Strength loss, low energy, poor sleep, and stalled fat loss usually aren't motivation problems. They're the result of inefficient training that never challenges the body correctly. Our protocol fixes the stimulus — so your time actually produces results.
The Protocol
One method. The same proven sequence, every visit.
Built for consistency and measurable progress. Four stations, about 15 minutes each — do one, or run the full circuit.
Red & infrared light + vibration
Cellular & circulatory priming
Supports cellular signaling and circulation and prepares the body for strength work. The part of the protocol that looks — and feels — restorative.
BioCharger
Nervous system & cellular optimization
A fully passive session of synchronized light, sound, frequency, and PEMF — designed to leave you calm and clear before you walk back out the door.
CAROL Bike · REHIT
Metabolic & cardiovascular activation
A precise cardiovascular stimulus in minutes — supporting circulation, fat metabolism, and energy without the wasted time of long cardio.
The heart of the protocol
ARX: resistance that pushes back — perfectly, every rep
ARX is the piece our members rave about. A computer-controlled motor delivers exactly the right resistance for the force you produce — moment to moment, through the entire range of motion. No weights to set, no momentum, no guesswork.
As used by
The same adaptive-resistance technology used by performance and longevity leaders like Tony Robbins, Dave Asprey, and Ben Greenfield.
-
It matches your exact effort
Every rep is met with perfectly proportional resistance, so each one is fully effective — whether it's your first session or your hundredth.
-
It loads the lowering, not just the lifting
ARX challenges the eccentric (lowering) phase that ordinary weights leave on the table — a major driver of strength and muscle.
-
It lets you go all-out — safely
The machine only ever pushes back as hard as you push, so there's nothing to drop, no momentum, and no way to overload yourself. You get the results of full effort without the usual risk — gentle enough if you haven't trained in years, intense enough to challenge a lifelong athlete.
-
It measures every session
ARX records your output rep by rep, so your progress is something you can see in the numbers — not guess at.
The science — why minutes beat hours
Muscle isn't built in the gym — it's built when you recover from a stimulus strong enough to demand it. So the real question is how fast you can reach that stimulus.
With free weights, you can't get there quickly. A dumbbell only weighs what it weighs, so you challenge the muscle at the weakest point and coast through the rest — and the only fix is volume: more reps, more sets, more time. That's why traditional strength work eats a full hour and gets split across days.
ARX removes that ceiling. It pushes back at your true maximum through every inch of the movement — including the lowering phase, where weights can't load you at all — so you reach the full growth stimulus in one brief, all-out effort. Hit it that fast and the math flips: you need fewer sessions, not more, with real recovery between. Maximum result, minimum time.

Fitness + wellness, in one place
An hour at the gym is all fitness. Ours is fitness and wellness.
A spin class is an hour of just cardio. A lifting session, just strength. Pilates and yoga each train a single avenue. Our protocol covers two fitness modalities (cardio + strength) and three wellness modalities (red & infrared light, vibration therapy, and BioCharger) — all in one place. You're targeting five areas of your fitness and health, not one. Each station is about 15 minutes: pop in for one, or run the full circuit.
A typical fitness class
~60 minutes · fitness only
- ○ One area of fitness — just cardio, or just lifting
- ○ No time for wellness or recovery in that hour
- ○ An hour out of your day, several times a week
- ○ Crowds, waiting, and progress you guess at
One area, one hour — and no time for anything else.
The BioHack protocol
~15 minutes each · four stations
- ● Cardio — CAROL Bike (REHIT)
- ● Strength — ARX adaptive resistance
- ● Recovery — Red & infrared light + vibration
- ● Recharge — BioCharger (light, sound, frequency & PEMF)
Two fitness + three wellness modalities — do one, or run the full circuit. Measured progress every visit.
What it produces
Measurable on the inside and out
Structural
Improved strength, muscle, and bone density — the metabolic foundation for fat loss and lasting energy.
Systemic
Better circulation, improved sleep readiness, reduced inflammation, and greater day-to-day resilience.
Who it's for
Built for adults 35 and up
Whether you're a busy professional fitting real strength into a packed schedule, or staying strong, mobile, and independent at 60+, the protocol meets you exactly where you are.
Busy professionals, 35+
You've got a career, kids, friends, and far better things to do than live in a gym — you're not trying to be a gym bro. But building muscle, losing fat, and a healthy heart still matter, and two things can be true at once. The best part? Each station is about 15 minutes — pop in for a complete strength session, or run the full circuit. Reservation-based and open 24/7, so it fits the busiest life.
Active adults, 60+
Staying strong, steady, and independent isn't vanity — it's everything, and it's never too late to start. The protocol helps you build and protect strength, muscle, bone density, and balance — safely, with no heavy weights to drop and no momentum — so it meets you exactly where you are, even if you haven't trained in years. The payoff? The strength and confidence to keep up with your life — and the people you love.

“I have found the holy grail of resistance training. The ARX mirrors back as much force as you can produce — which provides the stimulus your body needs to signal growth and strength.”
“The best way to see and feel results with building muscle and recovery in the least amount of time. As a chiropractor, I am constantly referring my patients to BioHack.”
“I notice the difference in my bones, my muscles, my resting heart rate and overall health at 62 — including my mental health. I highly recommend it for any age, especially seniors.”

Text (727) 469-7555Questions
Good questions, straight answers
Is this safe if I haven't trained in years?
Yes. The ARX resistance is computer-controlled, so it only ever matches the force you produce — there are no free weights to drop and no momentum to fight. It meets you exactly where you are on day one. Your membership also includes four complimentary personal training sessions so you start with confidence.
How is this different from personal training?
You actually get both. Your membership includes four complimentary personal training sessions to master the protocol — then every visit after is self-guided, following the same proven sequence yourself. The technology delivers a trainer's precision, objectively and repeatably, so you get expert guidance up front without paying for a coach every single session.
I'm already fit — will this take me to the next level?
Almost certainly. Because ARX loads both the lifting and lowering phase of every rep and adapts in real time, it can challenge a trained body far more completely than fixed weights — and the objective tracking shows you exactly how you progress, session over session.
Why prioritize strength if my goal is fat loss or energy?
Muscle is the metabolic foundation for lasting fat loss and day-to-day energy. Most plateaus aren't a motivation problem — they're an inefficient-stimulus problem. The protocol fixes the stimulus first, which supports the results that follow.
How do I track progress?
Objectively. The protocol captures performance data each session, so progress is something you can see in the numbers — not something you have to guess at or feel your way toward.
How often do members follow the protocol?
The protocol is short and efficient by design, and sessions are fully reservation-based around your schedule with 24/7 access. We'll recommend the right cadence for your goals during your free consultation.
How much does membership cost?
Membership is $299/month — one flat rate covering the full protocol, 24/7 reservation-based access, four complimentary personal training sessions, and our 6-month strength improvement guarantee. It's month-to-month, and most members start with a free consultation and studio tour to make sure it's the right fit before joining.
How long is a session?
Each of the four stations takes about 15 minutes. You can pop in and do just one — for example, a complete, measurable strength session on ARX in about 15 minutes — or string together the full four-station circuit to cover cardio, strength, circulation, and nervous-system recovery. It's flexible by design, which is why members with packed schedules actually stay consistent.
