Apparatus 10 for a golf swing training device comprising a golf club 20 with a shaft 24 with a grip 22 at one end and a club head 26 at the other end of the shaft with a cup 12 attached to the face 14 of the club head with the cup opening on the front towards the intended target. The bore of the cup 12 conforms substantially to the diameter of the ball 28. In use, a ball 28 is placed in the cup 12 with the intention of releasing the ball from the cup at a desired point during the swing at a target. In practice, if during the back swing the cup 12 is incorrectly tilted, due to poor swing mechanics, the ball 28 will fall out. Also, if the bore of the cup 12 is not in alignment with the target line at the ball's 28 point of release the ball trajectory will be skewed from the target. As an additional element, the cup 12 can have a circumferential ridge 40 on the interior to impede the ball 28 from easily falling out and the cup can be removably attached at 36, 38 to the club face 14.
