Flex, remember had calf implants aswell so that makes the statement about his lower body being superior invalid. I prefer kevins fuller musculature to flexs uber round muscle bellies. Bodypart analysis would read something like this.
Chest - kevin even post tear
shoulders - flexes are great, icnredible round like cannonballs but levrones are unique in the history of the sport
back - flex for detail, kevin for width - overall flex
bis - flex without a doubt
tris - kevin,kevin, kevin
forearms - flexes suck, kevins are good
quads - at his peak levrone without a doubt (he claims they were closing in on demayos in size)
hamstrings - kevin
calves - kevin
abs - draw
Bodypart superiorirty to kevin but of course we know its not all about that.
what about poses
front double bi - flex
back bi - flex
rear lat - kevin
front lat- kevin
abs and thigh - draw
side chest - kev
side tri - kev
most muscular - kev
again kev wins and his better win record would support him being better, but ive got a feeling we never saw the best of flex, whether he could match kevin in that footage from 97 is pure speculation. Could anyone though?
