This is awesome, I showed that move to my 6 year old, and it has added 15 yards to his drives. (now 80 yards). I gave him the feeling by tying some rubber strecth bands around his waist and standing on his right side and pulling it while he does his back swing. He really has to stablize himself with that right leg to keep balance on his swing.

As for me, I am the thick body type, and that position with the left foot back creates an awefull slice and lost of ball distance for me. I usually hit with the right foot back 2-3 inches from square. both feet flared. But ball position is critcal in that stance, every club the ball has to be in the right position or I am dead which leads to inconstentcy.

OK thanks
