This drill takes care of the rest of Smith’s backswing. Smith “sets” the club at waist high, pauses, then completes his backswing. At waist high, Smith wants the club shaft to be parallel to his target line and the clubhead perpendicular
to the ground.
He completes his backswing by
feeling his navel and right shoulder
turning in unison around his spine.
This ensures that he uses his core to complete his swing, instead of lifting
his arms.
“When my right shoulder, core and chest are turning, I can feel the club rotating along the plane,” Smith said.
