An exercise machine has a pair of exercise mechanisms pivotally coupled to the frame of the machine for use by an operator in performing a biceps curl exercise. Each such mechanism includes an exercise arm 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 rotates about the first axis. A linkage member pivotally coupled to both the frame and the exercise arm connects the two axes of rotation. An additional linkage member is connected between the exercise arm and the frame. Exercise resistance is provided by weights, although other sources of exercise resistance may be used. 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 linkage members. 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 triceps, leg curl, and leg extension exercises.
