Gripping a golf club like a professional gives a golfer a sense of confidence. The idea that you are holding the club like the top touring pros should leave you with the feeling that you are capable of hitting great shots. It all begins with the grip and you might as well grip it like a pro.
Take hold of the club with your left hand about 1/4 inch underneath the butt end of the grip. This should give you the positioning with your lead that you need to make a strong and powerful shot whenever you have the opportunity.
Your right hand needs to be set properly. Your small finger on your right hand will go right on top of your left hand between your first and second fingers. Your right hand should be holding the club firmly with strength. It is not just going along for the ride. It has a strong purpose and that is finishing the swing.
Align both of your thumbs down the shaft of the club. Your thumbs will fine tune your swing and make the on-course adjustments as you are about to make contact with the ball.
Make sure you grip the club very firmly, but not too tightly. If you grip it too tightly, it will restrict your swing. If you don't grip it tight enough the club head will not make solid contact with the ball.
Take hold of the club and grip it as if you were about to swing. You must feel comfortable before you start your backswing. If you need to make any adjustment, you need to turn your left hand just about a 1/4 turn to the right. That will help both hands work as one.
