I really like his physique, square jaw, sharp condition, good symmetry. Hard aggressive posing, good legs and a bald head makes me want to 'unload' over his image.
Jack is one tall handsome dude. Lean well muscled physique. Fill out a pair of skimpy posers very well...this guy's the whole package.
Jack Sullivan is one of my favorite US bodybuilders. I really like his choice of posers, especially the black ones.
