My problem with that is working biceps before back and tri's before chest
I gotta have thur off to rugby train.
Don't do it in that order, do back first and then bi's, and chest then tri's. It's never a good idea to work bi's or tri's before you do a more major muscle like back or chest. That said though, back and bi's is probably my absolute favorite combo to train; but of coarse I do back first.
