Didn't you use roman bench? Each side and back? Then oblique twist (wood chopper)?
What about straight arm pull down on cable? That also does core secondary. There are several others that sneakily do core. I do crunches in BJJ so it's not in my routine. You basically have twist, stomach, back and straight obliques (roman bench) and secondary touching. Roman bench is boss though.
I might need to repost my routine for you, it changed a little maybe they weren't in the first draft.
