Use Your Lifeline
See the black line I drew on my palm? Every palm reader knows this follows the lifeline. It's also where your putter grip should fit in the lead hand of your putting stroke.
Hold your putter so your fingertips press the grip into your lifeline. Now stand at address and swing your lead arm back and forth, like a putting stroke.Complete your grip, making sure the putter is against your lifeline and your wrists are bowed forward so the shaft runs straight down from your forearm. There should be no wrist hinge in the stroke.
You should feel that the putter is part of your lead arm, not part of your hand. For the best putting of your life, use your lifeline and your arm.
