First off, JStrider is completely right in telling you to focus on your triceps too. Increasing your tricep size will dramatically make your arms look bigger and better too. However, when you are doing your bicep routine, make sure to do three different types of exercises when doing your biceps and make sure to work them untill fatigue. Rotate the different exercises every few weeks to keep your muscles shocked, but ALWAYS do a few sets of standing barbell curls. Those are the absolute best exercise for your biceps because they target the entire muscle. Also, remember that your muscles grow when you are resting. Dont work your biceps more then twice a week. Eat plenty of protein as well. Hope that helps
