i think sergio's bis and tris insert further down the limbs but the forearms are very similar in attachments. frank has more peak, but sergio was never known for that.
this is where the rest of the physical proportions create the illusion of more muscular size. although arm againt arm by itself, frank probably has larger bis (from those pics anyway) when you take in the overall impression of sergio's taper, head and joint size his arms look bigger than frank's.
has there ever been a bodybuilder with the overall combination of size and shape that sergio had?
