Lifting Requires Brain Work, Too
Arnold understood and often wrote about the role of the brain in bodybuilding. When he trained, Arnold concentrated with 100 percent focus, which allowed him to reach even greater intensity levels. "The first step is to really believe that becoming massive is possible ... In the same way you can command your muscles to lift heavy weights when everything else suggests that you cannot, so you can mentally coax your muscles to grow larger and stronger."
Arnold's use of visualization techniques is well-known; he often imagined his biceps as big and peaked as mountains, and he harnessed that mental imagery to take his physique to unparalleled heights.
