Abstract

A lateral exercise apparatus for use in performing side-to-side skating movements having a surface layer for performing the skating movements on each side thereof. Each side of the surface layer has a very low coefficient of friction. A plurality of adjustable clamps are utilized to adjust the length of the surface layer with each adjustable clamp including at least one pair of releasable clamping surfaces for gripping the surface layer. Each of a plurality of resilient bumpers are removably interlocked to one of the releasable clamping surfaces of each of the adjustable clamps for terminating the side-to-side skating movements. The resilient bumpers are wedge-shaped and have a low impact surface angle Θ of less than or equal to 20°. Finally, a high friction layer is provided for underlying and securing the surface layer to a floor surface. In a preferred embodiment, the surface layer is comprised of high density polyethylene while the high friction layer is a combination of nylon and polyvinylchloride. The high friction layer is placed between the surface layer and the floor surface to eliminate movement of the surface layer. The length of the surface layer is hand adjusted by the clamps. The bumpers are removably interlocked to and adjusted with the clamps and are utilized to initiate and terminate the skating motion. The low impact surface angle Θ of the bumpers is orthopedically correct and minimizes potential for injury.

Claims
