Smith had been asked why, given his enormous proportions and prodigious raw strength (400+ lbs at 6’0 or so, incline Smith presses with over 700 pounds, 1000+ lb single leg presses, Smith squats with 9 plates, side laterals with 150 lb dumbbells etc etc) he didn’t compete in powerlifting.
He responded in his usual sarcastic fashion. I believe he was giving an example of why HE felt a powerlifting style of training was not suited to him, and not an indictment of the sport itself.
As to his claims about adrenaline: who knows? On the one hand, having read virtually everything the man ever wrote I can say he was not beyond a little exaggeration in his writing. On the other, he was a steroid guru and wrote reams on cycling, dosage, exotic drugs, site injections.
In any case, the only reason it came up is because he was a big mofo and this is a thread devoted to them. Enough about that.
