Getting the Proper Setup
According to Mike Davis, the first step to getting the proper setup is to get the shaft square with your forearms and on the same plane. He also recommends facing the target line so that when you stroke through the ball, it is easy to follow the lowest point of the arc. He emphasizes that it is important to be comfortable and not to set up in an awkward or weird stance.
Mike Davis suggests rotating your shoulders around your neck and letting your arms and the club move back and forth from one side to the other. He recommends focusing on a symmetrical swing back and forth, as this will help the putter work on the correct part for whatever your setup is.
Developing Feel
Mike Davis explains that there are three steps to developing feel. The first is focusing on correct motion or technique. He recommends taking golf balls out on the green and hitting them across the green with no target, focusing on what your body is doing.
The second step is developing feel. Davis suggests focusing on what the ball is doing and learning how to control energy. He recommends variable distance drills, looking where you want to go, taking a rehearsal swing, and feeling the amount of power you need to hit it.
The third step is aiming at a target with a goal-oriented drill. Davis suggests using balls at different distances from the hole, trying to hit each putt into the safe zone. He explains that if you can hit balls into the safe zone from about eight different distances, both uphill, downhill, and level putts, you know your putting is going to be really good.
