Well, to be honest, I would scrap it
You have to think large body parts then to smaller body parts. Your biceps are dinky little muscles... why fatigue them before a bench press, which works them anyways? In fact, with a bench press, you don't even need bicep curls.
Think of it like a statue - you carve out the shape/figure first - then you work on making a perfect human-like finger after. Weight training is similar - you work on major body parts (bench press, squat, rows) and then later on you work on the minor details.
