Oksana Chusovitina

When you think of gymnastics, it wouldn't be far-fetched to imagine that every single Olympic participant in the event would be a teenager with an elastic body. Perhaps this is why German gymnast Oksana Chusovitina's story is so incredible. She's 37 years old and can still twist her body into impossible shapes, and is participating in her sixth Games. 

She's the first female gymnast to have ever accomplished such a feat. Considering she won a silver in the vault at the World Championships last October, she's definitely got what it takes to compete at the highest level even now!
