Claim:
A weight exercise machine comprising: a first frame including a first shaft; a second frame operatively associated with the first frame and pivotable relative to the first frame about the first shaft; at least one first weight including an aperture, the first shaft passing through the aperture to pivotally join the at least one first weight to the first frame, and the at least one first weight pivotable relative to the first frame about the first shaft; a second shaft including at least one cam thereon operatively associated with at least one of the at least one first weight to selectively operatively associate and to selectively disassociate the at least one of the at least one first weight with the second frame; and a weight selector operatively associated with the second shaft; wherein: the weight selector is rotatable around an axis; the axis is substantially co-axial with the second shaft; and when the second frame is pivoted relative to the first frame: the at least one weight pivots relative to the first frame about the first shaft when operatively associated with the second frame; and the at least one weight remains substantially stationary with respect to the first frame when the at least one weight is disassociated from the second frame.
