ABSTRACT:
An exercise arm apparatus has a stationary frame member, a first pivoting arm pivoted to the frame member at a location intermediate its ends for rotation about a first pivot axis, a second pivoting arm pivotally connected to the frame member for rotation about a second pivot axis spaced from the first pivot axis, and a connecting link pivotally connected to the first arm and second arm to form a four-bar linkage. The first arm is an exercise arm with handles at one end for gripping by a user, and the connecting link is of sufficient weight to form a counter-weight to counter-balance the first exercise arm into a rest position corresponding to a start position for an exercise movement. In one example the connecting link is a solid, elongate bar of heavy metal or equivalent material.
