First set up without a club. Make a backswing. Let your shoulders turn then just let your arms drop without moving your shoulders. Once you can do that then as your arms drop let your shoulders follow your arms. Then take your club and copy the same routine. Set up in a closed stance. That gets your trail hip out of the way. It makes it easy to turn. Then let your arms just drop and then as the club swings down let your arms pull your shoulders into impact.
