im starting to do cable crunches. i am NOT doing them to make my abs more visible, i understand that is only possible with watching your diet very carefully. and because i am trying to bulk up, eating a small amount of calories and doing cardio makes no sense. anyways, i was wondering if its ok to work out the abs daily. some people say they need 48 hours of rest like any other muscle, but other people say its fine for them to be worked out daily. what are you opinions?
