How does Arnold Schwarzenegger use imagery in Arnold: The Education of a Bodybuilder?

Imagery:

"It was the summer I turned fifteen, a magical season for me because that year I'd discovered exactly what I wanted to do with my life. It was more than a young boy's pipe dream of distant, hazy future-confused fantasies of being a fireman, detective, sailor, test pilot, or spy. I knew I was going to be a bodybuilder. It wasn't simply that either. I would be the best bodybuilder in the world, the greatest, the best-built man."

"And all my rehearsing really helped me. I stood right next to Tinnerino and watched him constantly out of the corner of my eye. When he showed his abs or thighs, I hit a biceps pose; when he twisted to flex his calves, I drew myself up in a dramatic side-chest-back pose. I wiped everybody, including Tinnerino, off the stage. I got the best reaction - it was the first time I remember people really screaming 'Arnold! Arnold!'"
