Standing Too Far From The Ball
In giving thousands of lessons over the last 20 years, the most common mistake I fixed almost daily was golfer's standing too far away from the ball with the centre of their hips behind their heels with arms reaching out too much.
Most golfer's found it surprising just how close the pro's stand to the ball.
This C curve posture demonstrated by Jack Nicklaus is my preference.
Jack has the centre of his hips over the balls of his feet and his neck rounded so his eyes can use foveal vision our most proficient vision source.
People have been taught to keep your chin up, this is nonsense with the idea to make way for the shoulder to turn under the chin. If you have to lift your chin up to turn your shoulders your shoulders are turning to level.
