Off subject: Building bigger biceps?

[makoshark]

I have been taught to do push exercises one day and pull exercises another. Working bi`s and tri`s in the same day contradicts my teachings. I was taught it helps to isolate the muscles better and keeps from working the same muscle 2 days in a row the same way. Your arms get worked out on all the upper body routines, so it`s suppose to help in giving them a bit of a break.
