What is Adaptive Resistance?
ARX's unique feature of adaptive resistance ensures that each repetition is perfectly matched, in both the push and pull motion, during your workout so that you receive the exact right amount of resistance automatically at every moment of your workout.
Traditional weights are
failing you.
-
Wasted time on long workouts
-
Plateaus that never break
-
Joint pain and injuries from fixed weights
-
Zero feedback on whether you’re actually getting stronger
We felt the same frustration —
so we ditched barbells and brought in ARX.

Versatile All-in-One Design
One machine hits every muscle, every angle, every goal — strength, power, athleticism, rehab.
Unmatched Safety for All Ages and Abilities
No momentum, no dropped weights, no joint shear. Computer stops the instant you do — perfect for 15-year-old athletes and 85-year-olds alike!
Proven 40–60 % Superior
Peer-reviewed studies: ARX builds strength and muscle up to 60 % faster than free weights or machines — with less time and zero injuries. Numbers don’t lie.
The world’s smartest resistance — it fights you exactly as hard as you can go.
