A golf club swinging apparatus configured to support and provide for motion of a golf club along a pendulum swing path may comprise a frame, a rotation mechanism having club and frame coupling components, and an angle measurement mechanism. Another embodiment may comprise a frame, and a rotation mechanism configured to couple a golf club to the frame and to provide for rotation about a rotation point such that the golf club may follow a pendulum swing path through a strike position. Yet another embodiment may comprise a frame having a base component, a vertical component, and a cross-member component, a rotation mechanism rotatably coupled with the cross-member component, and a protractor having a freely rotatable arm configured to couple with the golf club and measure an angle at which the golf club is rotated about the rotation point along a swing path.
