Abstract: A golf swing trainer consists of a support base for supporting a vertical shaft, the shaft having a flexible horizontal shaft extending from it and having at its other end a golf tee upon which a golf ball can rest. The horizontal shaft is capable of moving up and down in a vertical direction on the vertical shaft and remains relatively fixed to the vertical shaft by a suitable means. A player would practice using the golf swing trainer by hitting golf balls placed on the tee, initially when the horizontal shaft is at a high position relative to the support shaft, and when the player become adept at hitting the ball at the high position, the horizontal shaft would gradually be lowered, so that the player would be hitting the ball at lower and lower positions. This promotes the proper swing plane for the golf swing.
