In one embodiment of the present invention, a tubular body defines a handle and sleeves at each end of the tubular body. Hollow fillable add-on weights include an outer wall that defines an annular step that is sized to be received within a sleeve of the tubular body. The add-on weights are engaged with the tubular body by a peg and thru-hole or dimple arrangement that holds the add-on weights against rotation and axial separation within the sleeve of the tubular body. The add-on weights and hollow body combine to form an annular indentation around which a strap-on weight can be fastened. The strap-on weight includes a hollow flexible elongated pouch, one surface of which includes a recess having a fill nozzle projecting therefrom onto which a cap can be mounted for filling the hollow pouch with water, sand or other suitable material. An attachment strap extends from one end of the pouch and includes a number of snap-on holes spaced along the length of the strap. The surface of the pouch also includes a pair of raised buttons projecting from a reinforced wall of the hollow pouch onto which the holes in strap are snapped so that the pouch can be retained in an encircling relationship.
