The sleeve can rotate freely on the shaft through a limited angle, and the apparatus includes interlocking components to set the angle so that, during a final part of a lift, the center of mass of the weight will be farther from the user than it would be if it were mounted on a standard weightlifting bar that passed through the center of mass of the weight. Braces are attached to the sleeve and go in back of the user's forearms to provide assistance in supporting the weights in the offset position. | |
