What is the AlterG

The AlterG is an antigravity treadmill that we have, that we utilize in rehab, especially with overuse lower extremity type injuries. What it does, is it actually suspends the athlete over the treadmill, and decreases their bodyweight, so that that way, they have less impact on that overuse type injury.


The AlterG is an antigravity treadmill that suspends the athlete above the treadmill and allows for a decrease in bodyweight on the injured area, such as the knee or the ankle. This allows the athlete to continue running without the pounding of their body weight on the injured area.
