Since biceps are a much more simple muscle than most, should they get worked as much as other muscles? My biceps are definetely my most lagging muscle but that is because I don't work them. They are not small, but they are not as big or strong as I would think they should be relative to my other lifts.

^- That's a ramble...
Biceps get worked in other lifts, just like forearms, which is why i have never really worked them. They dont's have a "day", every few weeks, if i feel like it, I will just do a few sets of curls.

I really am not looking for bigger biceps, I just dont want to be disproportunate when I, hopefully, get bigger.

Is it bad to do this or should I have a "day" when I work biceps?
