Abstract
My pneumatically sustained, flexible exercise surface-and-platform, which I call a "Trampol-air," initially designed for foot-ease along with all the benefits of exercising in any jogging-like manner on a flexing-resilient mini-trampoline-like surface, consists of a flat, flexible exercise surface supported by pneumatic tubing located underneath the outer edge (and, optionally, beneath the surface across the center area) of the exercise surface. The surface consists of a sheet of woven polypropoline (or other suitable material) which covers the pneumatic tubing and fastens at the back of the exercise platform's base (which extends out several inches beyond the exercise surface). The base may be made of a sturdy substance, such as one-inch thick plywood, or of thinner metal with a one-inch upward-curving circular lip around the edge. On the underneath-area of the base there is an access hole (or doors) large enough for putting air into the pneumatic tubing.
