Abstract
Abstract A step for performing exercises is circular to allow approaches from any direction equally. The step has a base member and a platform member, the platform member being selectively movable with respect to the base. The base has a plurality of grooves, and the platform has a plurality of tongues to be received in the grooves. There are grooves of different depths so that, by selecting the proper grooves for the tongues, the height of the platform can be changed. An elastic may hold the base and platform together while allowing adjustment.
