Very stupid question because it proves nothing. Someone with a well shaped, hard 16 inch arm will look much more impressive then a fat lard ass with a 19 inch arm. Ive seen it too many time. The fat bloated kid at the gym with a pumkin head and zits all over his back measuring his arm. Then going aroun bragging that it is 20 inches when it would be 15 if he dropped all the fat and water he is carrying.
