Ironmen: "Dan Rupert crouches inside a 180-pound frame of chrome-myolybdenum steel alloy like a man wearing the bones of a robot gorilla. Metal bars cantilever over his shoulders and down along his arms, terminating in menacing, knuckle-dragging hooks. At his feet, an industrial screw drive hums quietly. Rupert, a high school engineering teacher from San Diego, isn't trying to look like a supervillain. He is trying to lift a 650-pound barbell in front of a crowd of several hundred people. The exoskeleton - nicknamed Technotrousers - is supposed to make it happen."
