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 heart of the protocol
ARX: resistance that pushes back, perfectly, every rep
The piece our members rave about: a computer-controlled motor that matches your effort perfectly through every inch of every rep. No weights, no momentum, no guesswork.
As used by
The same adaptive-resistance technology trusted by
Tony Robbins,
Dave Asprey, and
Ben Greenfield.
Every rep is met with perfectly proportional resistance, fully effective from your first session to your hundredth.
ARX challenges the eccentric (lowering) phase that ordinary weights leave on the table, a major driver of strength and muscle.
Nothing to drop, no momentum, no way to overload yourself: gentle enough after years away, intense enough for a lifelong athlete.
ARX records your output rep by rep, so your progress is something you can see in the numbers, not guess at.
Independently proven, not our claim
Better results than weights, in a fraction of the time.
90%
greater strength gains
Years in the gym with little to show for it usually means the stimulus was too weak. In the study, ARX users gained nearly double the strength of the weights group in the same 12 weeks.
2×
more muscle mass
Muscle is what keeps you strong, capable, and metabolically healthy as you age. Participants built twice the muscle of traditional lifting, with nothing to lift and nothing to drop.
2.5×
greater fat loss
Stubborn fat rarely yields to cardio alone. Muscle supports your metabolism, and in the study ARX users lost 2.5 times more fat than the group lifting weights.
3.5×
more cardio fitness
VO2 max is the fitness number longevity researchers watch closest. In the study it improved 3.5 times more with ARX, strength and cardio benefit from the same short sessions.
72%
less training time
The stat for packed calendars. Study sessions ran about 15 minutes instead of 45, so a real strength habit finally fits a lunch break. And we are open 24/7.

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, and ARX reaches that full stimulus in one brief, all-out effort instead of an hour of volume.
Read the full science →
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.
A full strength session in about 15 minutes, not 45.

Learn about CAROL Bike & REHITWhat it helps with
Come in with a goal. We map the protocol to it.
Most people don't walk in wanting "a workout." They want to solve something specific. Here's how the protocol supports the goals we hear most, honestly, with no medical promises.
Losing muscle with age
Muscle slips away from midlife on. Resistance training is the most effective way to build it back, at any age.
Build muscle after 50Thinning bones
Loaded movement signals bone to stay dense. ARX lets you train for bone density safely, with nothing to drop.
Strength for bone densityStubborn fat, slow metabolism
Muscle supports your resting metabolism, and short REHIT cardio adds to it, for a leaner body without endless cardio.
Train for fat lossLow energy and fatigue
Better strength and fitness make ordinary days feel easier, so you finish them with more left in the tank.
Train for more energyWho it's for
Built for adults 35 and up
Busy professionals, 35+
You've got a career, kids, and far better things to do than live in a gym. But building muscle, losing fat, and a healthy heart still matter. 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. With nothing to drop and no momentum, the protocol builds strength, muscle, bone density, and balance safely, 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.
One system, not a scattered week
Most routines scatter across a week. Ours runs as one system.
Strength one day, cardio another, recovery squeezed in when you can. Our protocol sequences all of it into one measured session, so you never have to pile on hours to get there.
The well-rounded week
Spread across many trips
- ○ Separate days for strength, cardio, and mobility
- ○ Recovery is an afterthought, if it happens at all
- ○ Plus the overhead nobody counts: commute, changing, waiting for equipment, rest between sets
- ○ Crowds, and progress you mostly guess at
More trips, more hours, and a lot of it isn't even training.
The BioHack protocol

Member stories
In their own words
Real members on the protocol and their results.
“I've spent real time around training equipment, and BioHack Studios is doing something I haven't seen elsewhere. Fifteen minutes leaves me as worked as an hour of regular lifting used to.”
“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.”
“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.”

Questions
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 onboarding sessions so you start with confidence.
Do I get help learning the protocol?
Yes. Your membership includes four complimentary onboarding sessions to learn the protocol with guidance. After that, every visit is self-guided: you follow the same proven sequence yourself, and the technology delivers coach-like precision objectively and repeatably. You get expert guidance up front, then train on your own schedule, with no ongoing coaching to pay for.
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 a key metabolic foundation that supports 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 onboarding sessions, and our 6-month double-your-strength 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.
