Patent ID: 7131934

Claim:
An exercise platform system, comprising: (a) a platform having a top surface for a user to step upon and a lower surface, said platform top surface defining a plane; (b) a riser having an upper surface opposing said lower surface of said platform, said riser upper surface defining a plane; (c) at least one spherical resilient member; (d) wherein said lower surface of said platform defines at least one recess for receiving a portion of said at least one resilient member and said upper surface of said riser defines at least one recess for receiving a portion of said at least one spherical resilient member; and, (e) wherein said platform, said riser and said at least one resilient member are combinable to form a plurality of exercise platform configurations with said at least one resilient member disposed between said lower surface of said platform and said upper surface of said riser and spacing said platform apart from said riser, said plurality of configurations including: (f) a first configuration wherein said platform top surface plane and said riser upper surface plane are substantially parallel, and, (g) a second configuration wherein said platform top surface plane and said riser upper surface plane are substantially non-parallel wherein said recess in said upper surface of said riser and said recess in said lower surface of said platform are each sized substantially equal to each respective portion.
