If you are an advanced golfer looking for more width and better left arm position at the top of the backswing here is a drill I saw Vijay Singh use on the practice range and it is a pretty interesting drill. He put the headcover under his right arm. Not to try to keep his right arm closer to his body, but to actually get his right arm further away. He actually wanted the headcover to drop down in his backswing. What this does for you is create width. So in the backswing you take the club back and hopefully you drop the headcover down to the ground. Then when you go to hit a golf ball you will do the same thing. Vijay is great for doing drills. I love watching him practice, I love talking to him, he knows a lot about the golf game and he has worked so hard in his life inventing some drills himself. I know that he loves drills, and this one right here, headcover under the right arm. We are going to line up and drop it in the backswing and swing. Remember, the glove goes under the right armpit, you drop it in the backswing, it gives you more width. It is a great drill if you need to improve the width of your backswing. It is an advanced players drill, try it, I think you will like it.
