Abstract

Abstract A golf swing trainer includes a hand grip and a shaft formed of a limp, flexible material which is connected to the grip at one end. The free end of the shaft is unravelled to form a soft tassel. In the preferred embodiment, the shaft is formed of a soft flexible nylon rope having a diameter of approximately 0.5 inch, and the characteristics of the rope are such that the rope will extend to a straight, stiffened form to create the feel of a correctly swung golf club only when the golf swing trainer is swung through the hitting area at a predetermined velocity and timing. The hand grip is, in one embodiment, constructed of a rigid material having an outer layer of a molded high friction material adhered thereto. Alternately, the entire hand grip is formed of the molded flexible material to form a flexible grip.
