Our exclusive S-Force Performance Trainer leverages cutting-edge sports science to help athletes of all kinds build speed and power in the drive phase of the sprint. 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 the fast-muscle fiber essential to explosive starts, challenging even elite athletes to elevate their drive-phase sprinting to new levels. Our quiet, smooth-moving build includes a backlit console for feedback, quick keys for instant access to training programs, foot platforms for stability and an ergonomically contoured seat. Low-impact movement patterns help protect joints, and the cord-free design means that the S-Force can be placed wherever it works best for coaches and athletes.
