Abstract
A weight plate for use with physical fitness weightlifting equipment so that the weight plate may be coupled to other weight plates and lifted together in a stack. Each weight plate includes a pivotal switch arm including a first end at which to receive a pushing force to cause the switch arm to rotate relative to the weight plate and an opposite end at which a curved fork is carried. In one embodiment, a center post runs continuously through the center bore holes of the weight plates. In another embodiment, an insert is located in the center bore hole of each weight plate to be mated to the insert from an adjacent plate. When the pivotal switch arm of any weight plate is rotated to a locked position, the curved fork is rotated with the switch arm into surrounding engagement with the center post or the insert.
