Mark Immelman, host of the On the Mark Podcast, shares 24 Advent Season Golf Tips to help you improve your golf swing. In Tip #9 Mark follows up Tip #8 with a Trail Arm drill, as used by Sergio Garcia, that will help you keep your trail elbow working in harmony with your torso. It will also help quell a "Flying Elbow" at the top of the backswing and it is a surefire way to eliminate that dreaded "Over the Top" move which leads to weak strikes and sliced shots.
