I'd honestly have to say that rear delts are probably the most under-developed thing on me, they are very hard to look really nice. What do you think is the most under-developed body part on most people?[/QUOTE
It is definately,without question,the calves.I don't have the best calves,but i work them very hard.i have put on a inch since working them and i started measuring them when i started to notice them looking better.I have heard people say they gave up and some people don't even try.It is verry annoying and frustrating how slow they respond,but luckily im stubborn/bull headed enough to say "f**ck you calves,i own yall,and you will get bigger"But i also see a mix of underdeveloped quads,shoulders,backs,and forearms(kind of in the calf category)
