When you lower your lower body tension by bumping your shoulders and using your hips, pull the bar down while lowering your hips. When pulling the bar, instead of lifting with your arms, strongly engage your lats to allow the bar to come out naturally through your scapula. With tension in the anterior deltoids, support with your lats as if doing an arm pulldown, and at the maximum contraction point, before relaxing, maintain tension in the anterior deltoids and lats (while pressing the entire shoulder down).
