ABSTRACT:
A machine for exercising the pectoral muscles having a pair of synchronous movement arms pivotable about oblique axes by the user moving the arms from the user's sides to outstretched convergent positions. A constrained linkage connects the movement arms to a vertical drive rod which drives a lever at the base of the machine. The lever drives a weight stack pin upwardly to lift one or more resistance weights keyed to the pin. The user is supported by a seat and backrest and linkages are provided to adjust the seat vertically and the backrest horizontally relative to the movement arms.
