ABSTRACT:
An adjustable, recoiling aerobic exercise bench which reduces the generation and transmission of impaction forces on a user's joints while performing conventional and power step exercises includes a resilient platform slidingly disposed in left and right housings which function to support the platform above and relative to an exercise floor surface. Lateral platform recoiling assemblies are disposed between the platform ends and inside lateral walls of the housings and are adapted to generate lateral, resistive, restoring forces when the platform is moved downward during operation of the device. A vertical platform recoiling assembly which includes a plurality of rigid tubular spring retainers and telescoping springs, is mounted beneath the undersurface of the platform and is of sufficient length so as to make contact with the exercise floor surface to generate a vertical platform resistive restoring force when the platform is downwardly compressed. The ends of the platform are freely movably mounted within the housings to permit longitudinal movement of the platform ends therein when a vertical force is applied to the platform.
