ABSTRACT:
An exercise machine has a pair of exercise arms pivotally coupled to the frame for use by the operator in performing a triceps press exercise. The exercise arms are coupled to the frame for rotation about two spaced-apart, generally horizontal axes. One axis is fixed with respect to the frame, while the second axis is fixed with respect to the exercise arms. A linkage member pivotally coupled to both the frame and the exercise arms connects the two axes of rotation. Exercise resistance is provided by weights, although other sources of exercise resistance may be used. The selected exercise resistance is transmitted by a flexible belt and pulley system to a cam attached to a cross member connecting the two exercise arms. A second belt is attached between the cam and the frame to control the movement of the cam within a vertical plane. As the operator applies an exercise force to the exercise arms, the arms rotate about both the first and second axes, the relative movement about the two axes being coordinated by the controlled movement of the cam. This method can also be applied to many other types of exercise machines involving a non-linear motion path, including, for example, machines for performing biceps, leg curl, and leg extension exercises.
