To quote Steve Reeves:
"I had no limitations, and I used extreme concentration. In other words, when I worked out, I'd concentrate on the movements, doing them nice and slow so that I could really feel the movement all the way up and all the way down. I used a full range of motion, and it really worked out well for me. What you have to do is create a superior line of communication between your brain and your muscles. And you can only do that two ways: by concentration and by practicing muscle control in your spare time when you're not working out. When you can flip those muscles (e.g. getting your biceps to twitch through brief, voluntary flexion), that means you have great communication between your mind and your muscle tissue. So by building up a greater, superior line of communication between the brain and the muscles, I was able to develop much faster and easier, in other words, I didn't put so much time into it. I'd work out three days a week for about two to two and a half hours a day. Probably two and a half hours counting my upper body and lower body, and the other four days a week I would rest because rest is just as important as working out."
