Trampoline -- no longer just an activity you do for two weeks in gym class. Imagine the gymnastics floor routine, only on top of a trampoline. Trampolining has been an Olympic event since 2000, for both men and women. No betting odds were found regarding this year's trampoline events. The US has yet to medal in trampoline and will have one competitor in both the men's and women's event this year. Hopefully they add crab soccer for the 2012 games.
