I've searched around for an answer to this question, but I still don't know the answer. I have been working out for almost 3 years now, and I have recently been focusing on my arms, but I feel that I must be doing something wrong. My biceps seem to be much "longer" than "thicker". In other words, they are bigger when you look at them from the side, but look skinny from the front. My question is: what exercises can I do that will make them look "thicker," as I feel that I would be a lot more confident about the way I look right now if I could work them out that way. Thanks a lot.
