I think Sergio was great but not the best genetics of all time.
In most of his pictures his back is relatively shallow and his back lat spread
was not that great.
There are a few pics where his back looks great but in the majority
it is not that impressive.
His did have some of the greatest genetics for delts though.
No site injections back then just humongous delts that Ronnie couldn't
match until site injections.
His arms were huge but lacked a great deal of separation.
His structure was near perfect for BB and besides a lack of great conditioning
everything else is true but a less than stellar back is a huge flaw.
Just going through google his back shots account for about 10% of the pictures
and ther's a reason for that.
