A golfer places the club behind the ball, holding it comfortably, and stands perpendicular to his target line. The ball can be played anywhere in the stance depending on the shot the player is trying to execute.
In the backswing, a golfer should try to rotate his shoulders to the maximum, to the point where his lead shoulder is almost pointing at the ball. The torso and hips also rotate backward, but the shoulders should rotate more than any other part of the body.
Swinging Through Impact
To swing through impact, the golfer should first begin with a movement of the hips back into the ball. The shoulders and arms should follow, leading the clubhead back into impact.
The hips, shoulders, and arms should all push through the ball, shifting your body's weight to the front side. Allow the momentum of the club to go through impact and around the back for a smooth finish. Trying to stop the club after impact puts an unnecessary amount of pressure on the shoulders and can lead to improper swing techniques.
It is important to reiterate the importance of the weight shift in the golf swing. Shifting your weight through the ball to the front side of the body greatly enhances a golfer's swing speed and power, therefore increasing distance.
The head should stay basically still through the swing and impact. Many great golfers have a little drop of the head as they reach impact and go into and through the ball. Do not lift your head until impact has been completed and you have followed through--it greatly increases the chance of a mis-hit.
