Elevate a utility bench. You have to use a cambered bar to get the correct ROM. On the concentric, drive your elbows back and squeeze your shoulder blades together as hard as you can. In the eccentric, control the weight down and let your shoulder blades spread apart and stretch. Not being able to pull with your legs and low back like on a T-bar row makes these brutally hard. Another great variation is to drape some gains across the bar. To make these even harder pause each rep at the top while pulling the bar into the bench.
