I followed this in the early 90's when I was in highschool and kids would come up to me and ask me if I was on steroids. I was all natural and just worked my butt off in the gym Mon-Sat, 3-4 hours each day. I followed his plan for building mass and one of the things he emphasized was resting longer between sets. It worked but I also had the body type (Mesomorph) that could put on more muscle than other body types but by the same token I also had a propensity to gain a lot of weight if I stopped working out whereas some guys got thinner. The shocking of the muscles thing could very well be more psychological but anytime I couldn't get over a hump, shocking my muscles helped me get to the next level.. I typically chose 3 different exercises or more for each muscle and then did 5 sets each. For example for chest I did regular bench press, incline press, and dumbbell flys.
