I was watching TBS recently and the gymnastics movie 'Stick It' was on. I love to watch gymnastics during the Olympics (the only time I can find it on TV) so I watched it. It is actually a really good fluff movie. And by fluff I mean...I have nothing else to watch and I'm bored, lets watch this. Its not a super deep movie obviously, but if you like to watch gymnastics then its a good movie for you.
Another bonus is the lead actress Missy Peregrym. She reminds me of Kristen Stewert...but far more athletic...and hotter :P
If you like any of these moives/shows you will probably like 'Stick It':
