5'3 that's big..
I read in an old Flex that he was like 5'1 or 5'2. And in one of the vids he is listed as 5'4. There are a few pics of him in stage with Lee Priest, that should give you a scale of how tall he really was.
massive massive arms
and phenom abs
It's his huge triceps, and full biceps. Triceps are massive.
