Every man has a limit. No matter how tough, there is a pain threshold beyond which no man can pass, the point where determination gives way to submission. In the Octagon, a submission specialist sees an opening and seizes it. He sets a trap, and then springs it. He imposes his will and and breaks his opponent’s. If his opponent’s will does not break, his bones will. This action-packed collection brings you all the best submissions from superstars Georges St. Pierre, Anderson Silva, BJ Penn, Frank Mir and others who found victory by pushing the ultimate limits of pain.
