ABSTRACT:
Resilient exercise board comprising a generally planar platform having a laminated structure comprising a substantially rigid substrate and a pad of resilient material on one side of the substrate, and a plurality of resilient feet on the side of the substrate opposite the pad for supporting the platform in a predetermined position relative to a supporting surface. The resilient feet have upper sections affixed to the substrate and lower sections which can be swung between positions beside and beneath the upper sections to adjust the height of the feet and thereby position the platform in different planes relative to the supporting surface. The resilient pad is covered by a flexible cover having a skid resistant upper surface. In one embodiment, the platform has resilient reinforcing elements on the under side of the substrate.
