Does anyone know this song from the movie Whip It?

Their is a song that plays towards the end of the movie Whip It, when the Roller Derby girls show up at the pageant, into her dad telling her to go to the championship. It has a really fun upbeat sound and the lyrics are something along the lines of "show yourself...take over your dreams..." Something like that. If you know what it is that would be great I really liked it!
