Very hot man!!!
There's more of him here: http://www.musclegallery.com/ali/ and here: http://www.muscleweb.com/ali/ali-gallery-page.html -but photos you posted are far more appealing. Extraordinary man!
He is very bulked up in these pictures. He looks much more mature, in body and face, then he did when he won the Asian IFBB Championship in 2001. Still...he is HOT!
