Before, I used to have some lower back pain. Now, I lost a few inches from my stomach the back pain isn't as intense, but I can still feel it. But I noticed if I suck in my stomach (totally exhale and hold it in that position), I don't experience the lower back pain near as bad. Plus, my gut moves inward a couple inches. Does anyone know what is causing this? I do decline crunches all the time. I think its more than weak abs.
Thanks,
Don
