Another great aid in helping your torso and arms work together is a towel. Take the towel and place it around your chest and under each arm. Take your address position. While keeping your towel in place make some chip strokes. What you will find is that you have to press your arms into your torso with just the right amount of pressure you need in your arms for a chip shot. The added value of this exercise is that it gets your torso and arms to work together. Please remember the chip shot is a very controlled motion. If you have parts of your body moving separately, the more difficult the shot will be. The simplest machine is the one that has the fewest moving parts.
