Aerobic step device
First Claim
1. An aerobic exercise device comprising a platform having a block like base with a planar upper surface and a lower surface, said base having a pair of opposite ends, first locking structure in said lower surface of said base at each of said ends, an end module having first complementary locking structure for selective engagement with said first locking structure for elevating said base, additional locking structure at said lower surface of said base displaced from said first locking surface, and additional complementary locking surface on said end module located generally perpendicular to said first complementary locking surface for selective engagement with said further complementary locking structure for providing an additional height adjustment of said basesaid first locking structure comprises holes in said lower surface of said base, said first complementary locking structure comprising posts on said end module, said additional locking structure comprising a slot in said base and said additional complementary locking structure comprising a tongue extending from said module, said module further including a wall extending outwardly from said module perpendicular to said tongue to provide a support surface for said base when said tongue is inserted in said slot.

Abstract
An aerobic exercise step device includes a base and two end modules which may be engaged with the base at each end of the base in different positions for providing different elevations. In addition, a central module is provided which may be selectively mounted on top of the base to provide a further height adjustment or may be stored in the base with the feet in the central module being exposed to provide yet another height adjustment. The central module may also function as a separate step.
