Its about applying some practical common sense; for example: When doing rows (say bent over BB rows, traditional style): Which exhausts first? The upper back (which is a larger muscle) or the tinie-weenie bicep in the execution of the movement? Now, its true, the biceps (will of course) get stronger as time and progression moves on, but in the mean time, the muscle in the back isn't being worked....as much as it could be, if the bicep was stronger. Why wait--while the back isnt being worked like it could be (in this example I am giving). Apply som direct work, and having a stronger bicep is nearly never wrong, in bent over rows, in my opinion.
