ABSTRACT:
An exercise platform for use in a stair-step exercise routine and which is capable of supporting a person at a plurality of heights above a floor, includes a base section having first and second upwardly facing flat surfaces at first and second heights above a floor, and a riser section which is supported by the base section and includes third and fourth flat, oppositely facing surfaces. The riser section is connected to the base section with a hinge and is movable between first and second positions such that the third surface is upwardly disposed and located at a third height when the riser section is in the first position, and such that the fourth surface is upwardly disposed and located at a fourth height when the riser section is in the second position. Furthermore, a high friction coefficient material is disposed on the first, second, third and fourth surfaces to prevent slippage between the exercise platform and a foot of a person using the exercise platform.
