The Alter G® is a state-of-the art treadmill that is changing the way that people run. Whether you are recovering from an injury, an athlete training for a marathon, or have knee and joint problems, this machine allows you to run or walk by minimizing the stress on your body. 

Step into the machine in our specially designed shorts, zip yourself in, and feel like you are walking on the moon - all at a fraction of your body weight! Only available at the D.R. Semmes Family YMCA at TriPoint. Come in and defy gravity today!
