I would reccomend doing more sets and alternate. Biceps for me become very used to the a set routine and resulted in not changing. So maybe supplement preachers. I know that a lot of people are against these but I really feel it if you keep great form. Hammer curls also make your bicep much bigger by developing your brachii. I would also say to try switching up the speed and weight that you work your biceps. Sometimes you need to listen to your body rather than being a form freak.
