As the bar is being lowered by creating a tighter upper back, the major facet in creating this is maintaining the contraction of the LATS. It is the lats which keep the upper back locked into position.
If this is an unfamiliar feeling for you, upon receiving the bar, pull the shoulder blades tight together. Once this position is established, do not release it, and imagine bending the bar towards the feet with your pinky fingers.
