A question that I often hear is what can I do to improve and help make sure I am doing the correct motion with my hands during my golf swing.
The advice I always give is to hold your finish. Practice hitting little chips and pitch shots holding your finish. Make sure that the finish position you find your hands in is the one all great golfers have.
A flat left or lead wrist and a bent right or rear wrist. If you can learn to finish every pitch and chip shot with hands in this educated position that you will teach yourself the proper hand action through the ball which is No hand action.
Even if when you finish the shot your hands aren’t perfect put them in the proper educated position so that you can learn where you are trying to get to,
Try practicing this way and see if you don’t improve your short game and your full swing.
