ABSTRACT:
Exercise apparatus which enables the user to selectively perform a bench press exercise or a butterfly exercise using the same apparatus elements without requiring any modification to the apparatus by the user. A pair of exercise arms are mounted to a pivot bar for pivoting movement each about a respective one of a pair of parallel pivot axes and are interconnected for concurrent pivoting movement in opposite angular directions about the pair of pivot axes by respective intermeshed circular gear segments. The pivot bar is mounted to an overhead member for pivoting movement about a horizontal pivot axis. When a butterfly exercise is being performed, the apparatus provides equal resistance to both of the user's arms and insures that both arms move at the same speed. When a bench press exercise is being performed, the meshing of the circular gear segments locks the exercise arms together.
