Claims:

The invention claimed is:

1. A weight plate for physical fitness equipment including, a plate body formed with a center bore and two adjacent bores passing vertically through said plate body, aninternal bore formed horizontally within said plate body and communicating with said centrally located bore, an engagement pin movably mounted within said internal bore, and a lever adapted to move said pin within said internal bore to positively engagesaid weight plate to a center post pick up rod which selectively passes through said central bore.

2. The weight plate recited in claim 1 including, a swage pin for pivotally mounting said lever in said plate body.

3. The weight plate recited in claim 1 including, a face plate mounted in the side of said plate body to receive said lever.

4. The weight plate for physical fitness according to claim 1 wherein, said body is formed of a metallic material.

5. The weight plate for physical fitness according to claim 1 wherein, said plate body has no peripherally exposed holes.

6. The weight plate for physical fitness according to claim 1 wherein: said lever extends outwardly from said plate body so that the finger of a human hand may actuate said lever to either positively engage or disengage plate body.

7. The weight plate for physical fitness according to claim 1 wherein, said plate body is rectilinear in shape.

8. A weight plate apparatus including, a weight plate formed with an internal cavity and an actuating pin mounted within said cavity which pin may be positively engaged or disengaged by an external lever toggle switch which allows suchactuating lever to positively control internal mechanical pin locking system, a metallic bar having multiple throughbores wherein, said cavity is sized for slidable receipt of said actuating pin.
