ABSTRACT:
An exercise platform system and apparatus is disclosed that includes a plurality of angled step surfaces. In one aspect, the exercise platform can include an exercise platform base adapted to interface with a supporting surface and an exercise platform upper surface coupled to the exercise platform base that includes a first step having a first step surface, a second step having a second step surface, and a center landing area located between the first step and the second step, the center landing area being substantially parallel to the exercise platform base, wherein the first step surface and the second step surface are angled toward the center landing area by an angle between 5 and 30 degrees, inclusive. Further, the first step surface and the second step surface can be angled by a second angle between 5 and 30 degrees toward a transverse axis laterally bisecting the exercise platform base.
