You just might hate training back and bi's , that simple lol. I love chest/tri day and Back/bi day, but would rather be somewhere else on leg day. But, you gotta do it.
Besides, wheres the deadlifts man?

. Hmm, you are doing 2 exercises for the huge muscles of your back, and 2 exercises for those little bitty biceps. Make sense? NO. You are only training your upper back too with those exercises.
Deadlifts 2 x 5
Bent Over Rows 2 x 5
Pullups or Chinups 2 x 5
One curl exercise here. 2 x 8
Try this. These do not include warmups. Each set is a working set, which means you should be able to get no more than the reps suggested and should struggle to get the last rep.
Wait till you are
fully recovered, evne if it takes 5-10 mins, then hit the set again hard

. Just my 02.
