It's amazing how stringy and shit Arnold's physique was when off the heavy sauce.
Poor proportions and major imbalance. And serious "deflation" (not to be confused with general mass).
But with lots of pharma gear and intense weight training, his body became very unique and special, undoubtably.
Those pics were from '79, four years after he retired. He was doing a lot of long distance running back then, he may have even entered a marathon in Hawaii around that time.
I remember the year after he retired, he was doing a lot of guest posing only weighing 210 pounds, about 25 pounds less than his competition weight.
