billy has an "okay" back, that's all i'll give him. from the side it doesn't look like he works out, and his triceps have less definition than mine. considering i'm holding way more fat, that tells you how little development he has.
alexxx is way leaner, has a way better structure, downright great legs, and from the back is far more separated. i dare say alexxx's will appear larger even if he weighs less, and he'll be better conditioned by a landslide.
