Begin by lying face down on an incline bench at about 30-45 degrees. Hold dumbbells with a pronated-grip, inside shoulder-width. Keeping a slight bend in elbows, use your rear shoulders to lift the dumbbells as you exhale. Continue the lift, driving through your elbows until upper arms are parallel to the floor. Pause when arms are at 90 degrees, then slowly return to the starting position. Repeat this movement for all reps then dismount bench.
