Slices start with a bad grip.

If you were going to take 1 golf lesson and get your money’s worth as a new golfer it would be wise to spend it on the grip. The grip is the only thing connecting you to the club and has a huge impact on your ability to square the face. Too many golfers grip the club in front of them and get the left had too “weak” (crease formed by thumb and index finger too far toward left shoulder. )
The more your hands go to the right on the club (stronger grip) the more the ball will go left. If every new golfer had to take mandatory (drivers ed) and learned to grip it correctly we would have a large percentage of golfers playing in the 70s in a short amount of time. Thank god there is no drivers ed or I may be out of a job, and I love what I do for a living!
