Hi I have been reading the 8 steps to a pain free back, and i've been having trouble figuring out when my pelvis is in neutral. How do I know if its in neutral? Also, After I align my pelvis in neutral will I have to adjust my lower back to be upright? or do I just perform a rib anchor to eliminate the sway? The book mentions rib anchor to eliminate sway but never mentions how to get rid of a hunch.
