ARX Alpha & Omni
Real strength in 15 minutes a week.
ARX's adaptive resistance matches your effort on every repetition — pushing and pulling — so you get exactly the right load at every moment of the workout.
Two platforms. One breakthrough.
Full-body all-in-one
Motorized resistance that adjusts every inch of every rep — no more guessing which weight to load.
Like a cable machine, evolved — resistance that pushes back on both the lift and the lower, every rep.
Why ARX is different
The world's smartest resistance.
It fights you exactly as hard as you can go — every rep, every inch. No guesswork. No wasted reps. No ego lifting.
Adaptive Resistance Technology
Instantly adjusts to your exact force — perfect workouts, zero guesswork.
Precise Progress. Quantified.
Every rep tracked to 0.1 lb. Watch your strength skyrocket with undeniable data.
Ultra-Efficient
Full-body results in 10–20 minutes, twice a week.
All-in-One Design
One machine hits every muscle, every angle — strength, power, athleticism, rehab.
Unmatched Safety
No momentum, no dropped weights, no joint shear. The computer stops the instant you do.
Proven 40–60% Superior
Peer-reviewed studies show ARX builds strength and muscle up to 60% faster than free weights.
Guided every rep
A coach in the room. Data on the screen.
Every session is dialed in by a certified NextGym trainer. Force curves, output, imbalances — all captured in real time.
The numbers don't lie
Up to 60% more strength & muscle vs. traditional training.
- Perfect load every single rep — no cheating or form breakdown
- Safer than free weights (zero joint shear)
- Real-time data proves you're getting stronger every session
- Published peer-reviewed studies validate the protocol
Expert voices
What world-class performers say.
"I'm really excited about using it and the refinements over the last few years have been night and day."
"ARX is awesome. You will pile on muscle and strength doing one 15-minute workout per week. It's nuts!"
"There is no way to get this type of exercise with weights. ARX is the future of exercise."
Two platforms
Every movement, covered.
A single ARX session can hit every major movement pattern. Here's what's available across both platforms.
