Mike Malaska helps John understand the importance of having the correct grip.
The correct grip will help create the best speed producers with your wrists. Your left wrist serves as a chopping action, while your right wrist is more like a throwing or slapping motion. If you don't have the correct grip, it will be hard to achieve this.
Mike stresses to John that the club has to be in his fingers. For John to completely understand this concept, Mike brings out his famous sharpie. John gets a quick anatomy lesson on the difference between your fingers and your palms. Mike draws lines on John's hands to illustrate the separation. This fun example hammers home the message.
Mike then places the club along the black line with the club in his fingers. The more the club is in your fingertips, the more you will be able to use your wrists and apply the lever system.
Mike works with John to get the correct grip and shows him that because he has the club in his fingers, it is easier for John's wrist to lever on the backswing.
Mike emphasizes that if you don't have the lever system working with your wrists, it doesn't matter what you are doing with your body; it will not create more speed.
Mike shows John the best way to grip a golf club is to hold the clubhead above his hands which is the best way to align his fingers into the club. Gripping the club already in the setup position tends to move the club up into your palm. Once you have the grip in your fingers, you can drop the club down to set up for the swing.
John then takes some practice swings with his new grip and focuses on levering his wrists on the backswing.
