ABSTRACT:
Disclosed herein is a chest and bust machine defined by a base frame from which emanates a plurality of upwardly extending support rods on a pair of which is deployed a vertical back support and a vertically adjustable seat mechanism. Provided in front of the back and seat areas there is a pair of spaced parallel pivot arms pivotted to the base frame at its lowermost extremity and connected at an upward extremity thereof to a plurality of chains which interact with sprockets disposed upon a common axle which, when rotated, rotates a cam disposed therebetween. The cam is connected to a further chain which operates a plurality of weights the magnitude of which is selectable. Work is done by rotating the pivot arms away from the user of the machine so as to provide chest and bust development in such a fashion that the exerciser is constrained from allowing any other muscles to contribute in the exercise, and the work done is on a direct drive basis.
