ABSTRACT:
A highly manipulatable weight plate for use in human exercise includes a disk body having a mass sufficient to generate a human movement resistance force when employed in human exercise and containing at least one internally located bore having a central axis for receiving a disk body mounting apparatus such as a barbell or dumbbell. The disk body includes two generally opposed sides that are oriented generally radially with respect to the central axis and terminate in circumferential edges. An outer periphery surface extends between the circumferential edges of the two sides. At least one recess is contained in the disk body and opens into the outer periphery surface to allow radial insertion of at least one human finger therein so that the finger can apply an axial force against the disk body to displace the disk body away from an adjacent surface that is contacting one of the sides of the disk body. Examples of such an adjacent surface include a floor and a similarly sized weight plate.
