Flex was NEVER anywhere near as shredded as Ronnie downstairs. Maybe his genetic kidney condition made it difficult to dry out?
It could be, who really knows. Also, Ronnie would be too big for a 1998 AC Flex.
Here is a rare pic of Flex at the 1998 AC Prejudging. Great back as always, but from the waist down from behind is where Flex comes second best to Ronnie.
