This question really applies to all heavy core exercises, but does anyone think deadlifts should be spaced out more than once a week? Normally, I do back on monday and legs on thursday to try to seperate the core movements as much as possible (DL and Squat). Today, I couldn't do my normal weight in straight leg deads (leg day) because my lower back hurt. Could this be because it is still recovering from DLs on monday? Both emphasise heavy extension of the back. Should I lose SL deads and do some other ham exercise instead in favor of my normal deads?
