Many golfers tighten their arms and pull the club with their shoulders to start the downswing. This movement tends to steepen the path and open the face, and set up a golfer for needed early extension and or a stall to hit a shot online. But this limits the ability to create a good path of the club after impact.

To feel the timing of when to apply force to a swinging object, try this drill. Play around with the timing of when you add the force to the club and you will quickly see that there is a zone where you will get the most bang for your buck. Try to recreate that sensation when swinging the club after you do the arm shallowing piece.
