The ultimate performance series, the AlterG PRO Anti-Gravity Treadmill offers athletes the most robust solution in unweighted recovery and performance training. With NASA-Inspired technology, the PRO uses patented Differential Air Pressure (DAP) to precisely reduce gravitational forces on athletes by as much as 80% on a top of the line slat-belt treadmill, enabling earlier rehabilitation or increased training volume for peak performance with less risk of injury.
