This is the final piece regarding posture and maintaining posture during the golf swing.
Maintaining posture throughout the swing means that you are continually aimed at the golf ball and can truly swing the club, rather than having to “hunt” for or find the golf ball during the motion.
Please notice from the title that we are talking about the forward swing, not the downswing. The word downswing should be stricken from all golfers’ vocabularies. The motion should be intended to send the ball to the target not towards the ground. If the energy or exertion of the golfer is sent towards the ground the result will be a golfer whose spine angle moves towards vertical. This move of the spine angle is what is commonly referred to as “picking up.”
Too many golfers waste mental focus on staying down. Their focus should instead be on turning their hips then torso towards the finish, which will allow the spine angle to be maintained.
If the golfer tries to force the club towards the ground and ball, energy is thus being directed at the ground. According to Newton’s Third Law of Motion, every action has an equal and opposite reaction. Therefore, according to the laws of physics, a golfer making this downward motion cannot maintain proper posture during the golf swing motion. All the energy being sent down is equaled by the amount of energy being sent back into the golfers’ chest. This loss of posture will tend to result in thin shots, shanks and other undesirable results, because as the spine moves towards vertical the shoulders move away from the ball, the pelvis moves towards the ball and the golfer must then use hand-eye coordination to find the golf ball.
A golfer making a downward move, and at the same time trying to “keep his head down,” is attempting to defy physics.
From a good fundamental position at the top of the swing, the golfer must create a forward motion by establishing the lead leg as the axis of rotation, followed by a rotation of the hips. This sets the proper sequence of motion into action and will allow, according to the laws of motion, the golfer to maintain optimum posture.
