Abstract: An exercising device in the form of a barbell or dumbell is designed for the development and strengthening of the bicep brachii. To avoid pronation of the wrists and permit curling exercises in the palms up, supine, hand position, without undue and prolonged wrist strain, the center of gravity of the device is moved rearwardly away from the hand grip during curling. This is achieved by use of a cushioned, weight-distributing, plate which has a hand grip rod laterally offset from, but parallel to, a pair of longitudinally spaced, weight-supporting rods, each projecting from an opposite end of the plate.
