Lying with your stomach on an incline bench, have a loaded bar underneath you so that you can grab it once lying on the bench.
After having the bar in your hands, hinge your elbows back so that the bar comes up towards the bottom of your ribcage.
At the same time, slightly raise your heals off of the bench so that you get a little extra squeeze in your back.
Once the bar reaches the bottom of the bench, slowly return it back to the starting position so that your arms are hanging freely before repeating.
