Be like the Duke Lady Blue Devils golf team and play this jump back drill with your friends, wherever your putt ends up you have to jump the ball back the length of your putter and sink the following putt from that distance
A common mistake on the backswing is to hinge instead of cock your wrists, a perfect drill to help fix this is to pre set your backswing by cocking your wrists right up in front of your face at address and then turning into a full backswing
Whether you putt conventionally or left hand low the most important aspect of the putting grip is to have the club in the lifelines of your hands and have the hands opposing each other so that they work together and do not fight each other
