The caption under the picture reads: ” Massive Sergio, after abandoning the Weider System for two years, went from defeat to defeat. Now it seems that he’s coming back into it, to be trained by the master blaster of all time, Joe Weider. If so…watch for a fantastic new Sergio. No bodybuilder can do without Muscle Builder and the Weider System. Nothing is impossible with Weider Methods. With them Arnold turned a sloppy build and chicken legs into the world’s biggest. most massive, most cut-up physique…with fabulous legs that defy description. Just think…they measure a full 20 inches!
