ABSTRACT:
A handle has enlargements between a central gripping section and cylindrically shaped opposed end sections. The opposed end sections have free ends formed with male screw threads for the minority of their axial extents. A pair of weights are similarly configured. Each weight includes an inner center, coated outer layer, and a central cylindrical bore, and bushings in the bore. A locking nut is coupled to each free end of the handle. The diameter of the free ends of the handle is less than the diameter of the bushings for the rotatable coupling there between. An end cap is secured with respect to each weight. Screws extend through each end cap and outer layer. The screws extend into the inner center to join the end caps with respect to the weights.
