Abstract: Two golf practicing aids are disclosed, one for preventing the improper shift of a golfer's rear leg and the other for preventing the improper swaying of the golfer's hips. One of the aids includes a frame having a horizontal base, a pair of spaced apart standards at one end of the base, and an elongated arm extending from a central portion of the base and intermediate the standards. The arm is pivotably mounted on the base and may be adjustably attached to the standards at selected vertical locations. The free end of the arm has a yoke member against which the golfer may place his or her rear leg, and the base has gripping members for securely attaching to the ground. The other aid includes a belt having a U-shaped strip member projecting from the side thereof facing the forward direction in which the golfer is to hit the golf ball, the strip acting as a slideway along which a clip may slide.
