When you bench correctly every muscle in your body is working in unison, so the shoulders being taxed makes sense. What doesnt make sense is doing chest today and a seperate shoulder session tommorow. This will undercut recovery a limit growth. If your delts arent being utilized on bench, then your doing it wrong. If your shoulders are taking too much of a beating, than your technique probably sucks. Post a video of you benching so we can critique technique.
