Abstract
Abstract An adjustable height and length aerobic step/bench device includes a base having a horizontal platform with a depending skirt. The base includes connecting elements for detachably receiving legs so that the elevation or height of the platform can be varied. Additionally, the platform itself includes structural elements to selectively permit the length of the platform to be varied.
