The S-Force Performance Trainer combines a specifically designed motion and a magnetic resistance system to take high-intensity interval training to the next level. As members move through a user-defined path that fits their individual stride, resistance automatically increases the harder they work. This means even HIIT enthusiasts are pushed to their limit.
 
Our exclusive S-Force Performance Trainer leverages cutting-edge sports science to help athletes of all kinds build speed and power in the body’s horizontal acceleration position in less training time. As athletes move through a user-defined path that fits their individual stride, the magnetic system automatically increases resistance the harder they work. This progressively improves fast-twitch muscle fiber essential to explosive starts, challenging even elite athletes to elevate their sprinting to new levels.
