ABSTRACT:
A convertible gymnastic apparatus for doing push-lift movement or chest building movement makes use of a short cross bar having thereon a protruded bar extending upwardly and a swing frame comprising a longitudinal bar, to which a movable body is attached, and two gyrating arms having a baffle disposed at inner side end thereof. As movable body is moved upwardly, the movement of the baffle of gyrating arm is obstructed by the bump of the movable body so that the gyrating arm can not be rotated. Therefore, the user can do the push-lift movement. As movable body is moved downwardly, the protruded bar of the short cross bar is locked securely into the hole of the movable body, thereby resulting in prevention of the swing frame from swinging forward and allowing the user to do the chest building movement.
