Abstract
Abstract An aerobic step/bench exercise device includes a base having a horizontal platform with downwardly extending sides. The lower surface of the base includes a plurality of spaced leg receiving openings. Each of the openings has at least one notch extending upwardly from the lower surface into which a lateral projection from a respective leg would be inserted to control the extent to which a leg may be inserted into its respective opening.
