I think its just more proximal and distal tricep that u can focus on, and even that is up to genetics too. Nuk I was asking u if u had anything for your distal tri (on ur lat shrug post), but it just may be genetics, bc I used to be able to do a good amout (perspectively speaking) on dips, and behind the heads, and reverse grip, etc.. and the part closest to my elbow never grows =(
