An apparatus for simulating athletic running, throwing and swinging movements and for exercising and strengthening leg, arm, wrist, shoulder and back muscles used in such athletic movements. The apparatus is operated by the athlete and utilizes the athlete's body as a fulcrum to develop rotational motion such as arises in running, pitching, throwing and swinging motions. The exercise apparatus has an elongated rigid tubular member, with an attached hand grip at one end thereof. An exercise grip member is attached by an elastic cord to the opposing end of the tubular member and is used by the athlete to exercise the throwing/swinging arm or leg. Simulation of actual throwing and swinging motion, with greater freedom of movement on the part of the athlete during such exercises may be carried out with the device.
