 Several American presidents partook in the combat arts, but the toughest of them all has to be Theodore Roosevelt. Nicknamed the Bull Moose, Roosevelt was a sickly child until he took up the martial arts. He became an avid boxer and accomplished judoka and was known for holding secret wrestling matches while in office as both governor and president. He was as tough as they come. He once had his boat stolen by thieves and he quickly constructed another one, chased them down, beat them up and single-handedly walked them back 40 miles and turned them in. In 1912, he was shot in the chest by an assassin on the way to his speech and he did the 90-minute speech anyway saying, it takes more than that to kill a bull moose. And speaking of moose, could he be any more badass? In 1919, he died from a blood clot and vice president Woodrow Wilson was quoted as saying, death had to take him to sleep for if Roosevelt had been awake, there would have been a fight.
