Thanks for posting that, Tony.
I belonged to a weightlifting gym in NYC in the late Sixties/early Seventies. That era was the beginning of serious bodybuilding competition for big bucks. The gym subscribed to all the muscle mags. The top guys were Sergio, Ah-nuld and Lou Ferrigno, and I always thought Sergio was tops.
Alas, it was also the heyday of anabolic steroids. I wonder if they didn't contribute to Sergio's death.
