An arm exercise machine comprising: a frame; a weight stack comprised of individual weight plates mounted on said frame for vertical movement thereon; means for moving selected ones of said weight plates between lowered positions and elevated positions comprising: drive means rotatably mounted on said frame; first and second idler sheaves rotatably mounted on said frame; a third idler sheave; means for mounting said third idler sheave on said weight stack including means for selectively detachably coupling said third idler sheave to any selected one of weight plates such that said selected one of said weight plates and all of said weight plates thereabove are concurrently moved upwardly and downwardly between said lowered positions and said elevated positions; first line means coupled at one end to the uppermost one of said weight plates and at its opposite end to said drive means and trained around said first and third idler sheaves; second line means having one end coupled to said uppermost weight in said stack and the opposite end thereof coupled to said drive means and trained around said second and third sheaves such that when said drive means is rotated in one direction said selected weight plates will be moved by said first line means between said lowered positions and said elevated positions and when said drive member is rotated in the opposite direction said selected weight plates will be moved by said second line means between said lowered positions and said elevated positions.
