Fred Grzybowski has got to be one of the best pogo stick athletes in the world. The tricks he performs on his Flybar pogo stick are both huge and incredible. My favorite trick of his is when he does his double-backflip. It is also very impressive when Grzybowski jumps over automobiles of various types. One wrong move performing a stunt of this type and Fred could be in serious trouble. The mutliple back to back jumps are also impressive. Which of Fred Grzybowski’s pogo stick stunts are you most impressed by?
