One of our watches wrote in with a great observation on the stance, torque and body position. One of the many aspects of the PPGS that differs from the rest of the golf world is that we want to be behind the ball, stay behind the ball, and hit up on the ball - not down. Our goal is to tear the grass out of the ground and not take divots.
Now, of course, one of the obvious benefits of not taking a large divot is the physical abuse on your body. Shoveling dirt with a golf club isn't good for anyone's upper body. The other benefit is distance and accuracy. Also by hitting a ball in this way there is no fear of hard pan, cart paths, or hitting off mats!
