Backswing Drill to get you on the Correct Circle

I like to think of the backswing as a "tilted" circle.  The angle of this circle would be considered the "plane" of the backswing.  A plane which is too steep or too shallow will cause ball contact and directional issues.  This is a great drill to help you feel and develop a proper backswing. 

Work on small shots with a lofted club such as a 9 iron.  Give yourself some room so you do not hit the alignment rod which is set at an angle. I recommend placing the rod at least two feet behind your golf ball and set at the same angle as the shaft at address.
