Selector weight plate

Abstract

The selector weight plate includes a weight, preferably made from a metal, and a elastometric cover that completely encases the weight, which is designed to be used on standard stationary selector weightlifting machines. The weight is equipped with a central vertical aperture, for receiving the center post of the weighting machine, and two offset vertical apertures for receiving the guide rails provided on the weightlifting machine. The weight also has a pair horizontal apertures used to receive a selector pin that locks a series of selector weight plates in place. The elastometric cover is included through the vertical apertures and is provided to help prevent the deterioration of the metal weight and to help prevent loud noises that occur when successive weight plates strike one another during the course of a exercise routine.
