Lately, I've been experiencing lower back pain--right above my ass and sometimes to the right a bit--with my deadlifts (I do them once a week). This morning, I cut the weight dramatically and did 3x8 but still felt this pain. I concentrate on form, but maybe there's one thing I'm doing wrong that pulls in that area? My back is pretty weak, so I've been incorporating back extensions and other exercises to supplement my deads, in order to strengthen it. I wonder why, lately, this pain occurs.
