There's one classic Arnold technique that hasn't been mentioned so far in this blueprint program, which is isotension training. You probably know it by another name: flexing. It's not here because it's difficult to quantify the way that Arnold did it. It was simply a constant presence in his workouts. He recommended flexing during rest periods, after training, and of course, he spent plenty of time doing it during posing and competition. For him, this was performance practice, but it was also a crucial component of having mastery of his body and maintaining the mind-muscle connection.
"It isn't enough to have big muscles; you have to be able to control them as well, and that's something you have to learn," he wrote in "The Encyclopedia of Modern Bodybuilding." "A bodybuilder who poses and flexes in the gym, watching himself in the mirror, is engaged in a very important part of his workout."
Range of motion, heavy weight, and progression are crucial. They always have been and always will be. But don't forget about the power of pure, unadulterated tension!
