Abstract
A weight plate having rotatable handles is disclosed. By rotating, the handles provide a sure grip to the user, while allowing the user to perform various exercises without adjusting his or her grip on the device. The handles also facilitate the safe loading and unloading of the device on plate-loaded exercise equipment. The weight plate may thus be used as a stand-alone exercise device, as a weight plate loaded onto a barbell or dumbbell bar, or as a weight plate used on plate-loaded exercise equipment.
