South Korean archer Kim Kyung-wook won two Olympic gold medals at Atlanta 1996, in the individual and team events, but only after following a training regime which included attending a military base where she had go hiking along an open sewage ditch, sprinting with a car tyre strapped to her back, floating for half-an-hour in frigid ocean waters and rolling commando-style in mud. But she admitted the scariest things she had to do was being blindfolded in the dead of night, taken to a crematorium and told to fetch bones from the ovens and having to pick up a live snake and bite it.
