Set up to the ball. Drop your trail foot back until the toe of your trail foot is even with the heel of your lead foot. As you swing back, your trail hip will now be out of the way. This creates the space you need to swing your arms. On your downswing, leave your trail foot or heel on the ground. Your force or weight moves up to your lead foot, but your trail heel is still on the ground. This will help you accelerate your arms faster than your center.
