A weight plate for use with a barbell type exercise device wherein the plate is coupled to the apparatus\lifting bar for rotation during the exercise movement, which rotation is ultimately blocked by a leverage bar coupled to the plate for rotation therewith and positioned to contact the user\s outer forearm during the exercise movement. The plate includes protrusions and recesses on its front and rear faces for interengaging adjacently mounted plates on the apparatus so that the plates rotate together without the need for the leverage bar to penetrate all plates.

For use with an exercise apparatus of the type comprising (a) a pair of longitudinally separated weight plates for providing a movable weight-training mass and 5 having respective centers for gravity; (b) a generally cylindrical lifting bar extending generally longitudinally between the weight plate

For use with an exercise apparatus of the type comprising (a) a pair of longitudinally separated weight plates for providing a movable weight-training mass and 5 having respective centers for gravity; (b) a generally cylindrical lifting bar extending generally longitudinally between the weight plates and mounted thereto at first respective locations on the plates offset from said respective centers of gravity; (c) means for permitting rotation of the weight plates about the lifting bar as the apparatus is moved by a user; and (d) a leverage bar extending generally longitudinally between the pair of weight plates and mounted thereto for rotation therewith at respective second locations on the weight plate means different from the respective first locations, the leverage bar being positioned to rotate with the weight plates about the lifting bar so as to contact the outer forearm of the user during the exercise movement, a weight plate having front and back faces, the faces being generally symmetrical about respective first axes of symmetry and being asymmetrical about respective second axes, the first and second axes associated with each face being relatively orthogonal, the points of intersection of the two sets of first and second axes being co-linear with the plate\s center of gravity, the plate including first mounting means for mounting the weight plate to a lifting bar, said first mounting means being located with respect to at least one face at a first position on said first axis and offset from the from the intersection of the face\s first and second axes, a first discontinuous surface feature associated with one of the front and back faces, and a second discontinuous surface feature associated with the other of the front and back faces, the first and second surface features being respectively interengagable with corresponding second and first features of adjacent weight plates on the apparatus to cause the plates to move in general unison about the lifting bar.
