A golf swing training device including a training ball constructed of a compactable, resiliently deformable foam material, the training ball including at least two generally flat club impact surfaces each formed along a chord plane angled between approximately five degrees and twenty-five degrees from vertical and spaced from the center of the training ball with each of the at least two generally flat faces being substantially covered with a releasable adhesive material. A club face releasable adhesive material is removably mounted on and substantially covers the ball striking face of a golf club and the releasable adhesive materials on the training ball and the ball striking face cooperatively operate to releasably engage with one another upon impact of the ball striking face with the training ball thereby generally causing the training ball to be releasably retained on the ball striking face at the location of impact.
