Try working your back along with bis, throw in some supersets. Do pull-ups then go straight into a set of curls, use a weight you can do 4 second negatives 2 second positives with GREAT form for about 10-12 reps, no half assin. Once you get close to failure, use momentum to get the weight up, and continue to do the 4 second negatives.

Get that intensity up, no reason why your arms should not be sore 'at all' if your intensity is right.

Mine don't get sore sore, but I always know I worked them the day after back/bis
