Abstract
An improved exercise apparatus is described. The apparatus comprises a cylindrical element and a flexible member associated with the cylindrical element. The flexible member is movable between a wound configuration, in which the member is wound around the cylindrical element, and an unwound configuration, in which the member is unwound from the cylindrical element. The apparatus further comprises a recoil means biased to move the flexible member to the wound configuration and a resistance means that resists movement of the flexible member from the wound to the unwound configurations. The resistance means comprises an energy storage device, which is in a geared relationship with the cylindrical element. In a preferred embodiment the energy storage device is a flywheel.
