Golf Chipping mandates a shortened backswing. Those who take a full swing while golf chipping will quickly become frustrated with shots that travel much farther than intended. When you shorten your backswing it allows the club face to strike the golf ball with less force, while also letting you accelerate through your shot. The best way to reliably shorten your backswing is by keeping your back arm straight. There is only so far that the human body can rotate the golf club without bending the elbow. Shortening your backswing in this way will bring consistency to your backswing and golf chipping. Each shortened swing will be just like the last instead of being randomly longer or shorter.
