I would dop the rep range in my aux work. Try doing pause reps 5x5 with a solid weight, and a super set of dumbbell skull crushers, and double arm hammer curls. 3x8 on skulls and 1 minute each set of curls.
On your second day do some inclines and OHP stuff. Along with crazy high rep tri work (20-50 rep per set. Think of this blood flow day.
