Another golf drill you can practice is to practice drives with a tee in front of the club. Just tee up a ball but set the club face at the back of it. Stick the tee about an inch from the golf club's toe. Now practice hitting drives without clipping or touching the tee in front of the ball. If you are clipping the tee, then your swing is still in an out-to-in path thus causing slice. Keep at it until you can hit drive after drives without ever clipping the tee.
A good golf swing mechanism is one of the best techniques you should practice to fix slice. Here's a golf drill to help you develop a good swing and consequently help you eliminate slice. Keep your left arm attached to your chest, the clubhead out of your hands, and the club halfway back. Your left wrist should be cupped, your right knee flexed and your right arm above your left. Keep the butt of the club into your abdomen area and grip the shaft just below the handle. Keep the shaft off the ground and at approximately the same height as your knees. Then keep in mind that your arms, torso, legs and hips work as one unit. Keep practicing to achieve a strong and confident swing.
Another golf drill to eliminate slice is simply to practice putting anytime you have the opportunity. A few practice putts everyday will train your muscles, develop your stance and balance and help you develop a smooth and fluid motion that will keep your swing path from going outside-to-in. At home or at work, try practicing a putt during breaks. This can easily add up to help you achieve a better game play and eliminate slice.
These are just three of the many golf drills you can use to help fix slice. There are many more golf drills you can try which can effectively improve your fundamental skills and strengths so you can greatly improve your game play.
