1. A weight apparatus, comprising: a bar comprising a body having an axial opening and at least one radially extending pin, the radially extending pin being movable relative to the body between an innermost position in which an outer end of the pin is radially inward of an external surface of the body and an outermost position in which the outer end of the pin extends radially beyond an external surface of the body; a rod having a cam, the rod being axially movable in the axial opening of the bar, the cam having a cam surface in contact with an inner end of the pin, the cam surface having a radially outermost portion and a radially innermost portion, the rod being movable between a first position in which the inner end of the pin contacts the radially outermost portion of the cam surface and the outer end of the pin is in the outermost position and a second position in which the inner end of the pin contacts the radially innermost portion of the cam surface and the pin is in the innermost position; a weight comprising a radially extending pin opening in which the pin is received to attach the weight to an anchorage when the outer end of the pin is in the outermost position and in which the pin is not received so that the weight is not attached to the anchorage when the outer end of the pin is in the innermost position; wherein the cam is in the first position when an end of the rod is even with an end of the axial opening, and the cam is in the second position when the end of the rod is axially internal of the end of the axial opening.
