Squatting, deadlifting, and don't forget Rippetoe's favorite accessory exercise - back extensions, or reverse hypers if you can find the setup - do wonders.
Pairing weightlifting with McKenzie Method work is great if you suffer from lumbar flexion back pain; the most common out there. Also, weightlifting works best for that type of pain as well due to it getting rid of anterior pelvic tilt over time and reinforcing a neutral spine, to say nothing of the increased muscle gain and postural support you get from pushing iron.
