ABSTRACT:
An exercise machine for the strengthening and development of shoulder muscles of an exercising person. The machine has a structural frame including a centrally-disposed upright body support beam with such beam bearing an adjustable height seat adapted to support the exercising person in a sitting position. Right side and left side arm abutment members are positioned for engagement by the forearms, in horizontal orientation, of the exercising person, such abutment members each being affixed to a supporting frame journaled to a journal box affixed to the upper end of the body support beam and located at a point above a shoulder of the exercising person whereby the arm abutment members may each be rotated outwardly and upwardly by movement of the upper arm of such person. Weights are carried by the supporting frame of each abutment member at the rearward end thereof and are adjustably positioned on such frame with respect to its pivot point at its respective journal box whereby a varible resistive force for strengthening and developing shoulder muscles is applied through the supporting frame and abutment member to the forearm of the exercising person in opposition to the rotative movement of the upper arm of such person in an outward and upward direction.
