Abstract: A weight plate includes a first section having an annular shape with a passage extending axially through the first section and configured to receive an elongated member therethrough, and a second section having an annular shape and positioned radially outward of the first section, where the second section includes first and second outer surfaces on opposite axial sides of the weight plate with an axial thickness defined between the first and second outer surfaces. The second section has a plurality of recesses each extending axially inward from the first and second outer surfaces at least partially through the axial thickness of the second section.

Abstract: A barbell comprising a bar member, a first side weight assembly and a second side weight assembly. The bar member has a first side sleeve region and a second side sleeve region opposite the first side sleeve region. The first side weight assembly includes a weight surface and extends over the first side sleeve region, and is rotatively coupled to the bar member through an inner and outer slidable engagement surface. The second side weight assembly includes a weight surface and extends over the second side sleeve region, and is rotatively coupled to the bar member through an inner and outer slidable engagement surface. The bar member includes a first and second surface enhanced region, the first surface enhanced region spanning a portion of the central region and the first side sleeve region, and with the second surface enhanced region spanning a portion of the central region and the second side sleeve region.
