ABSTRACT:
An apparatus is disclosed for use in the exercise of the human body, which comprises a fiberglass pultruded shape of a predetermined oblong geometry with an elastic sheath formed about the exterior thereof over the length of the fiberglass pultruded shape. The fiberglass pultruded shape has fiberglass filaments dimensionally stabilized in a hardened resin system. Material properties of the filaments in the resin system are selected such that the ultimate elongation design value of the filaments and the resin system is greater than the actual maximum elongation of the filaments and the resin system when the fiberglass member is flexed in the exercise process. Also, the resin is selected for toughness sufficient to provide a useful flexural fatigue life.
