Adaptive Resistance Exercise — ARX

Computer-controlled Motor-driven Resistance

Get the perfect workout in just minutes
  • Maximize intensity on both positive and negative phase of movement
  • Maximize "Time-under-Tension" to accelerate results
  • Displays, quantifies, and tracks performance in real time
  • Compare current performance to previous workouts
  • Safe and effective for beginners and experienced atheletes alike

ARX technology combines computer-controlled, motorized resistance that is capable of matching the force of any user 100% of the time. This gives you the perfect rep, every rep. With perfect resistance, ARX shortens the time you need to exercise while dramatically increasing the safety and effectiveness of all of your workouts.

ARX is resistance training technology that uses computer-controlled, motorized resistance in place of weights or other more traditional forms of resistance. This “adaptive resistance” provides safe, controlled, and quantifiable resistance that is of a higher quality than is currently possible with weights or other gravity-based systems found in the world today.

There is no need to set the resistance while using ARX; the machine applies perfect opposing resistance in direct proportion to what the user is producing at each moment in time. The machine moves the handles or foot pads at the selected speed during the positive and negative regardless of how hard a user exerts. The difficulty is determined entirely by the user, whose effort is measured and displayed by the software in real time.

ARX is safe for all forms of rehabilitation, offering the full spectrum of resistance ranging from passive resistance (stretching) all the way to eccentric loading (negatives). There are no weights to drop, the speed is manageable and controlled, and the machine can never act upon the user. This means that a user can never encounter any forces that they themselves did not first produce, and this never-excessive scenario dramatically lowers the risk of injury.
