Biceps are a secondary muscle when doing back. They shouldn't be that sore or fatigued from a back workout. If they aren't still fatigued 2 days after an arm workout, you aren't working them hard enough. Bi's and tri's are a secondary muscle group when working back, chest, and shoulders. You can work arms after they have been used as a secondary muscle, but shouldn't be used as a secondary muscle after you have trained them. For example, if you do tri's before chest, your chest workouts will suffer because your tri's will fail before your chest. hope this makes sense.
