What Is Adaptive Resistance?

Adaptive Resistance™ technology uses patented, motorized resistance and computer software to give you the perfect workout every time.

ARX will dynamically adjust the resistance you receive, in real-time, to automatically provide you with precisely the right amount of resistance you can handle on every rep of every set. This means that you never have to choose an amount of weight on ARX.

Our Adaptive Resistance™ technology handles this and other difficult parts of resistance exercise so you are free to perform your best without any of the guesswork that comes from using traditional tools like weights.

Quantify Your Growth

The ARX software brings resistance training into the 21st century, empowering users to track and quantify their progress like never before. With each session you have a private trainer to take you through the workout and go over your workout results. It's never been easier to track your total force output, max force output (concentric and eccentric), time under tension, and other improvement metrics.

The days of wondering "Am I improving?" are long gone! Precise and consistent, the ARX software tracks your progress instantly and automatically.
