As many people know I am a big believer in improving the path or plane the club swings on because it controls all factors of impact. Years ago I developed a “pillow” that helped me show and improve my student’s concept of the angle the club swings on. My plane pillow is roughly sits at a 45-degree angle.
I place the pillow to the side of the golfer with it aligned on the same angle the club is on. Usually it will be a 6- or 7-iron. The drill is to swing the club back along the angle of the pillow and then back along the angle on the way down. Many golfers take the club too much to the inside in the backswing and then way outside on the downswing. If they hit the pillow they get instant feedback on the club moving the incorrect way and with the pillow being so soft it will not hurt if they do hit it.
