Abstract
Abstract A dumbell-barbell with two or more separate, collapsible containers which are filled as desired with fluid. These containers are suspended below opposite ends of a sectional bar to which they are fastened by bearings which allow the completely assembled sectional bar to rotate. The lateral movement of the containers is restricted by retainers on the ends of the bar. For compactness, the sections of the bar separate, and the containers are removable.
