How The Shoulder's Move To Create Proper Attack Angle
In order to get the club head moving in a positive Angle of Attack, you need to swing the club so that once the club head bottoms out on the swing arc, the club head begins to rise up towards the sky as fast as it can. The way this is easiest to achieve is by rotating your shoulders down and under your chin.
