This is a video of Lyoto Machida discussing how he changed up his training before his fight against Thiago Alves at UFC 94: St. Pierre vs Penn. He says before he didn't do any strength or cardio training, but he added those in to try and become a more explosive fighter. It's a scary thought to imagine adding knockout power to Machida's already ridiculous skill set. If I was cornering any of his opponents, my advice would be to show up to the fight with a machine gun.
