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.Other References
