NASA Technology

AlterG®'s patented Differential Air Pressure (DAP) technology, developed at NASA, applies a comfortable and uniform lifting force to your body. Integrated into a high-tech treadmill, AlterG®'s technology offers precise body weight reduction and an easy-to-use set of controls. And because the AlterG® ADP technology uses air pressure as the lifting force, it feels comfortable allowing you to run or walk normally with a full range of motion.

Defy Gravity

The new standard of care in rehabilitation and training, the AlterG® Anti-Gravity Treadmill gives you the opportunity to exercise without pain, even while you are still recovering from surgery or injury.
