Another way to hit it all is to do bent over barbell rows. Try a supinated grip, and bring the barbell to your solar plexus. Your back will be at roughly 45 degrees from parallel to the floor, though a little lower or higher is fine. Bend your knees and arch your back a bit.
Like Phil said, pull through with your elbows, not your hands. This is good advice for chin/pullups too.
If that doesn't work, I don't know what will!
