Plyometric Exercise Apparatus

Abstract

A plyometric exercise device and associated method is disclosed. The device comprises a polyhedron with a plurality of side surfaces. At least two exercise platforms are mounted to a respective two side surfaces of the polyhedron, each of the side surfaces having a respective, opposing, parallel base surface of the polyhedron. The polyhedron is configured such that each of the side surfaces is at a different height above and parallel to a floor when its opposite base surface is set on the floor. A method of exercising using the device includes setting any one of the base surfaces on the floor and exercising on the exercise platform opposing the base surface at the corresponding height, and setting one of the other base surfaces on the floor and exercising on the exercise platform opposing the base surface on the opposing height.
