Today we focus on putting-
So why is the putter grip is flat or square compared to a rounded golf grip on a club?
That is because the flat grip helps place the hands in an opposing position where the palms are facing each other and the thumbs can lay down on the front part of the grip. This grip helps minimize wrist and hand action so that the putter face stays square and does not rotate through impact. The rounded grip of a golf club helps keep the grip more in the fingers so that the hands can rotate the clubface open and closed.
In this video, you will see how to do the conventional reverse overlap grip used by many professionals to minimize hand action and stroke the ball squarely.
