【The Geometry of GOLF】 8. The Geometry of putting 　(3) Don’t move your head

Golf coach often tells you not to move your head during putting stroke. In fact, when we look at Tiger Woods putting, his head does not move at all. However, in some professionals, we see players who move their heads. Most of the movements are follow-through from impact and the head moves to the right. That is because they try to keep the center of gravity of the body stationary. An average arm weight is 4.55 kg per arm at 70kg body weight. Since they are golfers, considering that their arms are a little strong. So both arms + putter weigh about 10 kg. Since this 10 km moves from side to side, the center of gravity also moves. If an object weighing 70 kg and weighing 10 kg moves from side to side, the center of gravity will move by about one-seventh of the distance moved. For example, if the center of gravity of both arms + putter moves to the left and right by 10 cm, the center of gravity of the body will move by 1.4 cm. In order not to move the center of gravity of the body, it is necessary to move the body to the left and right by 1.4 cm in the opposite direction to the arm movement. Even though both arms are moving, trying to stay the center of gravity, results head movement. To keep one’s head still, they have to move their body’s center of gravity from side to side. We may feel that the body moves to the right on takeback and left on the forward swing. Practicing putting stroke not to move one’s head while looking in the mirror or going out to the sun and looking at your own shadow is the first step for the putting like Tiger Woods does.
