Many pros will tell you that your grip pressure should be light. This is supposed to let the swing be free and let the club head flow through the ball with speed. However, how often do we really think about it? Grip pressure is a tough thing because we all try to do things with our swing.
Today I went to the range and focused on grip pressure and tempo. I really slowed down my tempo and tried to feel the weight of the club throughout the swing. It reminded me of the Whippy Club, where you almost have to let the club swing itself.
The result for me today was great. I hit the ball more solidly than I have been, my distances were more consistent, and my balls were straighter. So the next time you hit the range, take a few swings with a light grip pressure and see how it helps your swing.
