ABSTRACT:
A flotation barbell for water exercise which includes an elongated handle member to which are attached two identical homogenous buoyant triangular end sections, shaped in the form of a triangular prism having two triangular ends and three rectangular sides. The buoyant triangular end sections are attached to the ends of the handle member so that the triangular faces of the end sections are transverse to the longitudinal axis of the elongated handle member, and the corresponding sides of the two end sections are coplanar. The ends of the handle member are inserted into apertures centrally formed between the triangular end faces in each section. An end plate, preferably triangular in shape, includes a central protrusion which extends so as to affixedly engage an end of the handle member, with the end plate pressing against the outer end face of the end section. The end plate additionally includes as at least one, and preferably three, pin-like members extending from proximate the apexes of its triangular shape so as to penetrate and engage the end section. A grip-enhancing cover may be located upon the handle member between the two end sections. A preferred buoyant material for the homogenous triangular end sections is a chemically cross-linked polyethylene having a fine closed-cell structure.
