Damn bro I forgot those fuckin things too!! The retarded thing is that I did them for a while for my bis and they worked well I dont know how I left those out. What a jackass.
LOL @ Monstar.I have a hard time choosing exercises sometimes too.There are alot of good ones out there.As for the chins, with a close grip you are hitting the lats a bit, but you are emphasizing the biceps and compare a bodyweight chin to a barbell curl.More weight can be used in the chin through a greater range of motion.Makes it a little more productive in my experience.
I used to work my biceps directly but don't do that much any more. What I used to do is sit down on a thing with back support with a couple of dumbells and have my palms faced towards me. Then as my arm started to pass my leg I would start turning and at the top my arm would be turned all the way (supinated I believe). Then on the way down I would turn it back. Alternate between arms. This gives the biceps a full scretch and full peak or contraction and also gets the bracialis or whatever the hell is underneath into play. Tell me how it goes.
