Placing your hands properly on the golf club helps you better control the position of the club's face at impact. During the swing your body turns to create power. Since the body is rotating, the golf club must rotate at the same rate. In other words, the body and the club must turn together as a unit.
A fundamentally sound grip helps you create power and feel at the same time. Wrist action is a power source and gripping the club too much in the palm of your hand reduces wrist action. With the Leadbetter Golf Glove you will be able to have a loose grip but still have a strong grip.
