ABSTRACT:
An exerciser for the upper body including a frame supporting a seat whose position can be adjusted in the vertical direction, a weight assembly slidably mounted on a vertical track, an overhead cam assembly coupled by a cable to the weight assembly and which is turned by a seated user forcibly contacting a lever arrangement adjustably secured to the cam assembly. By adjustably orienting the lever on the cam, different starting positions for the exercises are provided enabling the user to perform forward forearm presses or rearward forearm presses. A second cam system has a pair of double cams, one on the right side and one on the left side of the seated user. Each double cam is coupled to the weight stack by a cable having a pair of branches on each end. One branch cable member is attached to the periphery of one cam of the double cam and the other branch member is attached to the periphery of the second cam of the double cam providing that resistance is applied by turning the double cam in either direction. By shifting the seat to the appropriate height, lateral extensions, tricep extensions, curls and deltoid extensions can be performed.
