PROBLEM: Hitting behind the ball or too high on the ball.
This is often caused by swaying during the swing. Any side-to-side or up and down head movement should be avoided.
To get the right feel, hit some practice shots with feet together.
During your weight shift, concentrate on keeping the weight on your right foot on the inside of your foot.Callaway FT-5 Neutral Driver
Check your progress by taking practice swings with sun behind you and watching your shadow.
Don’t let the clubface get ahead of your hands at impact.

Don’t sole the club at address.
Use an open, narrow stance.
Keep arms connected to chest and rotate body rather than
sliding hips laterally and jabbing at the ball with your hands.
Focus eyes on front of ball, with weight on front foot and wrists
ahead of ball at address and through impact.Callaway Ft-iz Driver
Be sure to make a complete follow-through.
There are a number of possible reasons for hitting behind the ball. If you are not shifting your weight
properly on the downswing, from the back leg to the front leg, your swing will bottom out before the
club gets to the ball. Also, if you do not keep your head steady, you do not know where your swing will
bottom out. Also, if you do not keep your leading arm reasonably straight, the arc of your swing will vary, so you can improve your consistency by focusing on these 3 areas.
