The Wide to Narrow Drill is one of my personal favorites for creating lag in the downswing. Good golf swings create a nice wide arc on the backswing and then a more narrow arc on the downswing. As deeper angles are created upon transition, power is increased. One of the most common swing flaws in the game is casting or releasing early which results in not only a huge loss of power, but also loss of control over the clubhead if it passes the player’s hands. This drill is a fantastic fix for this oh so common problem.
