A multi-axes exercise machine for strengthening muscles surrounding
shoulder joint of a user allows the user a range of motions about lines
of motion perpendicular to an arc of circumduction of the shoulder
joints. A pair of handholds is suspended from an arcuate guide plate,
which extends above a user station. By moving the point of securing the
handholds along the length of the arcuate guide plate, the user can
re-position the upper ends of the handholds from a location above the
user station to a position behind the user station. At all times, the
axes of rotation of the handholds are parallel to each other and extend
along a plane that contains the axis of circumduction of the user's
shoulders. A centerline of each handhold passes through the center of the
corresponding glenohumeral joint of the user during the exercise.
