If your lead shoulder barks every time you make a full swing, swinging harder is not the answer. One of the most useful tools I give golfers who are rehabbing a shoulder is also one of the simplest: the one-arm golf swing. It looks basic. It is not. Done right, it rebuilds control, exposes the compensations that are feeding your pain, and bridges the gap between the gym and the first tee without overloading a joint that is not ready yet.
