I want to share with you a drill that Davis Love Jr. used to use to fix all sorts of problems in the golf swing. If a player was coming over the top, we would take a club and hold it in front of us with our left hand on the butt of the club and the clubface on the ground, bend over a little bit, and then throw a ball with your right hand under your left arm towards the target. This will make your shoulders work a little bit more under as you go through, and if you have been swinging your shoulders over the top that might be a good drill for you to try. On the other hand, if you are someone who hooks the ball, are always coming from too far underneath the plane, instead of trying to throw the ball up in the air try throwing the ball into the ground. Now you can see I am actually turning my right arm over to throw the ball into the ground and I am swinging it from the right side of my body to the left side very aggressively. That is a good move to try to fix an underneath hooker. You have seen second baseman do this if you watch baseball, a lot of times they will grab a ground ball and flick it over to first and the runner is out, just by taking the arm and flicking it over from side to side. They do not even need to warm up. You can do the same thing with your golf club, right arm from right to left, right through the impact zone. There is a lot of firepower there without me using my body quite so much. Give it a try. If you can get your right arm moving from right to left side you will be amazed at how much you can pop that ball.
