I once asked Darden if he got any shots of Jones training Sergio but sadly he didn't. Sergio never looked better than when Jones was prepping him for the '71 Mr Universe.
I disagree. Sergio only went down there for a few weeks. How much credit could Jones take for his physique for "training" him for that period of time?. He looked his best around 1972. He used volume and plenty of it prior and after Jones. Anyone who trained in the same gym as Sergio will state the same. Three day classic split of chest/back, legs and delts/arms with a lot of sets.
