Slow Down Your Swing

• Slowing down your swing sounds counterproductive to trying to get more distance out of your drives, but it works. There is a reason your golfing buddies comment on how you "tried to kill that ball" when you flub up your drive.
  When we try to swing too hard, our bodies tense up. This makes us stiff and hinders a fluid movement which actually will generate more power. Try swinging your driver about 75 percent of your normal force. You should notice distance gains immediately. The more comfortable you become with this swing, the more you can begin to increase your swing speed.
  
  

Turn Your Shoulders

• Many golfers get too much of their lower body moving during their backswing, particularly those who are also baseball players. Power in your swing is generated by the coiling and uncoiling of your body. Keeping your legs and head still, while rotating your shoulders back, will increase the coiling effect through your torso.
  Stretching exercises can help you increase your shoulder turn and maximize the power you generate. Still, legs also will help you keep your weight forward. Not shifting the weight off the back foot hampers distance.
  
  

Tee it Up

• A common, and quickly fixable, error of many golfers is to tee their ball into the ground so that they contact the ball with the center of the club face. Teeing the ball higher, though, so that you contact above the center of the club face, will produce a higher launch angle and achieve more carry distance. This is especially important in this day and age of very large driver heads.
  The driver is one of the few clubs that you want to hit on the upward stroke, rather than with a descending blow. Moving the ball forward in your stance will help you achieve this.
