I'm semi-tall at 6'4 weigh about 225-230, i have long arms and am looking to beef up my biceps/triceps a little. i'm not worried about a peak in bi's really just want to make my arm thicker, right now i have a day set aside to just train my arms, i do about 9 sets for bi's and about 9 for tri's. get in the basics, skull crunchers, preachers, straight bar, etc... anyone have any suggestions?
