he wasnt a gymnast then if he only competed in trampoline....
trampoline isnt even a gymnastics event btw...
men's events are:
parellel bars, high bar, vault, horse, floor, and rings.
women's events are:
beam, floor, fault, uneven bars.
trampoline is only something we play on for training...say we're training a double front on the floor, we'll have to do it on the trampoline first. etc.
