Bicep and back workout. Need Help

Question

So i got info on my pecs but what about my biceps and back? My biceps are only about 9-10 inches across. Is there a good weight lifting excersize?

Answer 1

straight bar barbell biceps curls (with a bit of cheating on the last set)and skull crushers.  The last website is a good website for all information but it appears to be down currently maybe try it later.
