An improved golf club swing training system is provided for assisting golfers to improve their golf swing. The golf swing training system includes a golf club including a traditional shaft, head and head face. Moreover, the training system includes a light source for producing a plane of light. Preferably, the light source uses a laser for producing the plane of light which forms a light line when striking the ground or other flat surface. In addition, the swing training system includes a practice mat. The practice mat includes a plurality of substantially straight mat lines which are positioned and aligned to identify proper golf swing position at various points through a golfer's swing. The golf swing training system includes the golfer repetitively practicing his golf swing so that the light source produces a light line which aligns with the mat lines so as to reinforce proper golf swing position.
