ABSTRACT:
Exercise board comprising a generally rectangular platform having a laminated structure with a horizontally extending substantially rigid substrate and a pad of resilient material on the upper side of the substrate, and bars of resilient spring material extending along opposing side margins of the platform and permitting the platform to flex with a resilient action in response to the weight of a person who is exercising thereon. In some embodiments, the bars are arched and impart an upwardly convex contour to the platform. In others, the bars are eliminated, and the platform is fabricated of a fiber reinforced plastic and formed with an upwardly convex contour or arch.
