ABSTRACT:
A barbell system includes a grip having an axial length and an axial bore with a diameter and planar end faces and a contoured exterior surface. The contoured exterior surface has a maximum diameter at its radial central plane and at its ends and a minimum diameter at its radial intermediate planes symmetrically positioned between the central plane and the ends. The exterior surface is formed with three circumferentially positioned regions around the periphery to form flat ovals. The central ovals are all located in three planes 120 degrees from each other with a major axis parallel with the axis of the grip and shaft and a minor axis transverse to the axis of the grip and shaft.
