General rule of thumb is what works while off will work better while on.

Have to say that full body workouts will only work good at novice level IMHO, that is if your objective is bodybuilding. No way you can have any intensity training all mucles in one session.

Try it, you will never know what works best for you without trying it. For me HIT is whats works best, the bible is here: http://forums.steroid.com/anabolic-l...eon%2A%2A.html
