The head and shoulders shift to the right because of a pivot at the base of the spine, but little torque is produced. The left hip pops forward to counterbalance the body move to the right. The body will have to make a big shift to the left for the club to make solid contact.
The lower body slides toward the target, and the hips start to spin open. The head stays back, tilting the spine away from the target and leaving the swing's low point well behind the ball. The result of this move will be a fat shot or thin contact on the upswing.
The shoulders are tipped back, and the hands are pushed well in front of the ball. The spine is tilted away from the target, with the head behind center. Weight favors the back foot. This promotes a shift to the right side on the backswing.
Forward rotation diminishes through impact, because the body has not released from its posture. The arms have outraced the body, rolling over through impact and collapsing on the chest. Too much weight has stayed on the back foot.
