I'm sure there are a few here with better insight, but found this article in Scientific American interesting:

Is there anything I can do to build muscle in the low back besides weighted leg raises? I think I mentioned earlier but I have atrophied muscle in this area from an injury years ago and then compensating with surrounding muscles.
I have been putting a dumbbell between my legs, laying stomach down on a bench and doing raises, but curious if there is something else out there I can do. This muscle deficiency pretty much puts a hold on deadlift and even some other excercises until I get it much bigger and stronger.
