Shoulder muscle exercise machine

An exercise machine comprising:

• a plurality of structural elements including a main vertical beam, a horizontal beam and a base frame operable to be positioned on the ground, said main vertical beam extending vertically from the base frame and said horizontal beam mounted to and extending perpendicular to the main vertical beam;
• a left arm support cup coupled to the main vertical beam;
• a left-side pulley mounted to a left end of the horizontal beam;
• a left-side cable extending through the left-side pulley;
• a left-side handle coupled to an end of the left-side cable;
• a right arm support cup coupled to the main vertical beam;
• a right-side pulley mounted to a right end of the horizontal beam;
• a right-side cable extending through the right-side pulley;
• a right-side handle coupled to an end of the right-side cable;
• a seat mounted to the main vertical beam, wherein the configuration and orientation of the plurality of structural elements, the left-side pulley and the right-side pulley, the left-side cable and the right-side cable and the left-side handle and the right-side handle are configured to allow a user seated in the seat to position the user's left arm and right arm in the left arm support cup and the right arm support cup and pull on the left-side handle and the right-side handle to exercise the user's left side shoulder muscles and right side shoulder muscles;
• a weight assembly including a weight and a weight beam where the weight is movable along the weight beam and where the weight beam is mounted to the base frame at a pivot point, wherein moving the weight on the weight beam relative to the pivot point increases or decreases the weight of the exercises, said left-side cable and said right-side cable being coupled to the weight beam;
• and
• a stop bar mounted to the base frame and positioned adjacent to the weight beam, said stop bar including a stop pin that prevents the weight beam from being lifted higher than the stop pin.
