Drills

The Left Foot Over The Right Foot Drill

This is a great drill that will prevent swinging outside to in. I usually have a student begin practice by making half, with the left foot crossed over the right. During the drills, using a weighted club or weighted training aid that promotes forearm rotation will ensure the inside path and proper release. After using the weighted club, I will then have the student tee up a ball and hit shots using a 7-iron from this setup position. The first half-dozen swings should be similar to a chip shot. The next six swings should be at 40 to 50 percent. Once you start making progress, it won't take much time to go from a slice to a draw.
 The Right Foot Back Drill

The transition to a full swing will initially be difficult. The next step in doing so is in this drill. This is great for containing an over-anxious upper body. Take your address position and drop your right foot about 10 to 12 inches back. It may help to lay a club down and place your left foot in front or ahead of the shaft and keep your right foot behind just inside shoulder-width. Again, using a weighted club, we will have students make half-swings working on the inside path to the ball while emphasizing the proper rotation of the forearms through impact. After using the training aids, tee up a ball using a 7- or 8-iron and hit balls from this stance. As you see yourself becoming successful, hit a couple of shots off the grass and progressively widen your stance until you get to shoulder-width.

Other dills can be used to solve the same problem. You may have seen others on the range teeing up a ball with a headcover box or board outside and parallel to the target line with the front opposite the front of the ball. Initially using a normal swing, they will probably hit the headcover before the ball, but if they work at trying to make clean contact, the headcover will teach the proper swing path in to out. Although it doesn't sound like fun, keep the driver in the bag and use these drills to warm up each time you visit the practice range. With diligent practice, I guarantee success.
