The golden rule that relates to the upper body unit is
that once the elbows have been pulled close together and the upper back muscles put into a taut condition, the upper body unit must be strictly maintained in this condition from the moment the back swing begins, right through to the end of the golf swing movement., therefore the elbows must remain as close together as is physically possible at all times to ensure that the upper body unit remain in a compact condition.
However, regardless how tightly you hold the upper body unit, during the back swing movement the right arm will gradually fold.
As the hips force the upper body unit to rotate into the down swing movement you must hold the left arm close to the right shoulder and the right elbow tucked into the waist until the club head strikes the ball, the right arm will automatically unfold unless you hold it in the folded condition, therefore this unfolding of the right arm should be delayed until the club head strikes the ball, but importantly the right elbow will move away from your waist unless you concentrate on this action.
( You must keep the arms in a totally passive condition throughout the down swing movement.)
Any independent movement of the arms is only allowed at the point of impact, where the right arm is forced into the fully straightened position.
As the compact upper body unit rotates around the central core of the spine during the down swing movement, the shoulders rotate from a position at the end of the back swing movement where the left shoulder is pointing to the ball position, to a position at the completion of the golf swing movement where the right shoulder is pointing to the original ball position.
Therefore as down swing movement movement is performed, the only way that the upper body and the lower body can rotate independently and maintain the upper body angles, is to use the waist line as a universal joint.
Most people will find it difficult to hold the elbows close together throughout the complete golf swing, but also golfers will have great difficulty holding the left arm close to the right shoulder until the club head strikes the ball , simply
because they do no believe that enough power can be achieve by
this method. ( See VIDEO )
However I can assure you that when you also learn to delay the release of the golf club, you will not only achieve
plenty of power but also your accuracy will vastly improve.
