Ok guys I want to see what your opinions are. Me and my training partner do back and biceps the same day. We always do back first and then biceps. He is telling me we should switch it up sometimes. Now to me this is a good idea when it comes to stuff like doing incline chest first instead of flat once in a while. But when you do biceps first you really don't have enough strength to do back. Do you guys think he is right in switching it up everytime , doing back first then bi's , then the next time around doing bi's first and then back? Or is it better to always do back first (since it is such a huge body part and your biceps are so small) and then your biceps.
Please give me your thoughts on this.
