PGA Instructor, Rich Greenwood describes the benefits of having a One Plane Swing vs a Two Plane Swing for his student Margaret Miller. Margaret has had a tendency to take the club up too steep at the top of her backswing which was producing some low toe hits. Rich got her to use a headcover under her left arm pit as a drill to get her to feel the one plane swing. This position allowed her to shallow out the downswing easier which produced more of center hit with higher ball flight. Contact Rich at www.RichGreenwoodGolf.com
