How Adaptive Motion Trainers Work:

The Adaptive Motion Trainer (AMT) is similar to an elliptical machine, but is actually a combination of an elliptical, a treadmill, and a stepper. It has two rotating pedals and upper body swing arms, so your arms and legs move in sync with one another. You can alter the stride, leg movement, and pedal height to suit your particular needs.

Adaptive Motion Trainers may be a good choice for people with knee problems or other medical conditions that limit or disallow high-impact exercise. The AMT machine is similar to an elliptical machine because your feet stay on the pedals. This reduces the impact on your body and joints.
