lower back exercises to help strengthen?

[RunMav]

Just seeing what you guys do for lower back exercises to help strengthen it. I have a family history of lower back problems and sitting in front of a computer all day doesn't help that either...
Can anyone recommend any good ones?

DL, SLDL, Hypers, Pull throughs, Good Mornings

Ditto on the hypers. These have really helped to stabilize my lumbar/sacrum the last few weeks. Even though I thought deads and squats would take care of everything, I was wrong.
