A dumbbell type apparatus comprises a hand gripping surface mounted on an axle and engaging a pair of spaced apart circular wheel-weights rotationally engaged with the axle. The weights provide peripheral outfacing surfaces for rolling the apparatus on a floor surface. Each of the weights has a non-concentrically placed center of mass, whereby with the hand gripping surface held in one hand, the apparatus may be rotated causing the wheel-weights to spin and to thereby exercise the arm holding the apparatus.

1. A dumbbell type apparatus comprising: a hand gripping surface mounted on an axle; the axle further engaging a pair of spaced apart circular wheel-weights rotationally engaged with the axle and physically concentric therewith, the hand gripping surface positioned therebetween; the wheel-weights providing peripheral outfacing surfaces for rolling the apparatus on a supporting surface; each of the wheel-weights providing a plurality of cavities placed in positions lateral to the axle; and a plurality of weight slugs adapted for being threadedly engaged within the plurality of cavities; whereby with the hand gripping surface held in one hand, the apparatus may be rotated in space causing the wheel-weights to spin and to thereby exercise the arm holding the apparatus.2. The apparatus of claim 1 further comprising a pair of handles engaged collinearly with the axle and positioned laterally relative to the wheel-weights.
