Exactly. I don't think Sergio was well proportioned or "aesthetic" at all. His arms were what made him so impressive, but he was very unbalanced. When I think of the perfect physique, Arnold springs to mind. I think you should be between 5'11'' and 6'1'' to be considered aesthetic.
you must be blind, arnold was great but no one ever touches sergio on balance. he is the very definition of a perfectly balanced, proportional, flowing physique.
besides his arms, he had thick, well developed muscle everywhere else, all low insertions everywhere, no weak parts, tiny waist with no gut and wide shoulders....good calves, good thigh sweep, the perfect bodybuilder.
