ABSTRACT:
A arm extension exercise machine which utilizes a frame-journaled rotating effort arm which is mechanically linked to a frame-journaled rotating weight arm which, together with the frame of the machine and the connecting link joining them, form a simple planar double-rocking-lever four-bar linkage which acts in conjunction with the rotating weight arm to vary the resistive force applied to an operator's arm extending muscles through body-machine contact with the rotating effort arm throughout the range of the exercise movement.
