i honeslty have never liked the chest/tri and back/bi on the same day. for one i feel its easier too over train by doin such. two i feel after doin chest and pre exhaust my trics they arent at its full potentual in strength expecially when your pre exhausting them with 9 sets for chest and finishing with 9 sets for trics. same for back and bi.

i like something like this too really bring out muscle
