<p>An apparatus (1) and a method for performing a shoulder press exercise are disclosed. A user support (11) and a primary hinge (30) are mounted to a frame (10). A secondary hinge (32, 34) is mounted to the primary hinge (30). An arm (60) mounted to the secondary hinge (32, 34) has a handle (61) adapted to be grasped by the user. The two hinges permit displacement of the handle (61) in either or both the longitudinal and lateral directions against a resistance means. The resistance means may include an incremental weight stack (70) operably engaged to the handle (61) by belts (39, 40) directed by self-aligning pulleys (270). The arms (60) may be connected such that both handles (61) move the same longitudinal and/or lateral distance. To use the exercise machine, a user selects a weight for exercise, sits on the user support (11), grasps the handle (61) and pushes upward from his shoulders, moving the handle (61) longitudinally and laterally as he so chooses, overcoming the resistance.</p> |
