Face Pulls        

What exercise does: Consider this to be a pure, upper back width movement. You need to realize that without an extremely wide upper back, you will never develop the coveted x-shape of a bodybuilder. This not only isolates the upper back, it also blasts the rear delts into submission!

Implementation: (A) Stand in front of the pull down machine with your hands spaced on the bar wider than shoulder width. (B) Standing back, pull the bar to your face while keeping your elbows out. Now, squeeze your upper back muscles from 2-5 seconds, and lower under control.
