I've always done biceps on my back day and triceps on my chest day. The reason I figured was that the bis/tris get hit a little when doing back or chest so I might as well work them. I also wondered about recovery. If I did my chest one day and then tri's the next, that might not allow enough time for recovery. So my questions are,
1. Should I keep doing it the way I've always done it?
2. Can I do chest and back one day and then bi/tri on a seperate day?
3. Does it really matter?
