Achiem did have a blocky waist with very good even and deep abs, but blocky for early days bodybuilding. However, in sports (wrestling especially because of the constant impact) if you do not have a strong, thick and powerful waist you will break down real fast.....Some guys get away with it but they probably don't take as many bumps. After a few years of being a line man, wrestler, judo guy you will notice a increased development of the abdominal structure in general....Now the goal is to produce and not just to look good.
