There are three skills you need to become ab good putter. Roll the ball at the correct speed, roll the ball in a given direction, understand the slope of the ground that the ball will roll over.
Golf is all about the force you apply to the ball. The force e you apply to the ball is a by product of how you apply force to the handle of the golf club. How you apply for e to the handle of the golf club is a by product of the motion of your arms and hands. The motion of your hands and arms is a by product of the muscles you activate to bring about motion. The MATAS is designed to ensure you activate and strengthen the correct muscles resulting in longer straighter more solid golf shots.
The plane of motion and the direction of the force in that plane off motion is difficult to see until you use The Plane ID tool. This will allow you to take the muscle activation you built with the Muscle Activation Trainer and apply it to swinging your golf club.
