Oh come on guys, he looks pretty good for his age and would look much better with some extra mass, which he would have if he didn't overtrain so horrendously, I mean 7 hours a day, come on!!
He has also clearly had some torn bis and tris and that is what is owing to his oddly shaped arms.
His slightly bloated abdomen is likely due to his age and the build up of internal fat - this happens to everyone as they get older.
Your diagnosis is incorrect, this is NOT palumboism.
