International Classification:

Abstract:

The present disclosure is directed to a slip training device. The training device comprises an outer frame having two ends; a plurality of platforms disposed on the outer frame, and at least one rotatable element disposed below each platform for enabling the movement of the platform with respect to the frame. Each platform is configured to be either movable along the frame or stationary with respect to the frame. In use as a slip training device, a user steps on one end of the device and walks across the device, not knowing whether a platform is moveable or stationary. If the user steps on a moveable platform, then the user will need to use balance to prevent a fall. If the user steps on a stationary platform, then the user can walk across that platform normally. Whether a particular platform is moveable or stationary can be changed each time the user traverses the device.
