Why does pelvic tilting hurt the lower back? To me, pelvic tilting is a lot like lying on my back with my knees up. It helps my lower back. Or maybe, what I think is pelvic tilting is actually proper posture?
Arching my back causes my back pain.
Best for back pain is forward bends, IMO. If you can't touch your toes, spread your legs out wider.

I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and should tweak Primal to their own needs.
