The “V’s” of the golf grip refer to the area where the forefinger and thumb come together on both hands.
When you look at the grip from a face-on position, the idea is to have these V’s to be pointing in the same direction.
Depending on your swing, and type of shot you want to hit, the left hand “V'” can point anywhere in the shaded area above.
The same goes for the right-hand “V”. My goal in my swing is to always have the “V’s” aligned, no matter what kind of shot I am hitting. The more they both point toward my sternum, the easier it to hit a fade. The more the “V’s” point toward my right shoulder, the easier it is to draw the ball.
I have found that the weak grip works best for short shots, and the strong grip works best for long shots.
Here’s a good rule of thumb for the beginner golfer: Make sure the “V’s are aligned and pointing at the right arm-pit. Also, the beginner should use same grip for every shot. As you get more advanced, you can start to branch out and move the grip around for different types of shots.
