You might be right .
Legit 26-27 inch waist was Brian Buchanan, followed by Flex, who "claimed" 27 inches, and think that was at his Arnold classic weight of 216 pounds. Melvin does have small waist, and he is 5'8, but I doubt the 28 inches now since he typically is not in shape, and when blew peoples minds when he placed 5th in 2005, he had a gut.
Toney at least keeps a tight waist. Could do without his trunks pulled up his ass crack.
