I hate my parents!!?

My parents want me to be healthy and don't get me wrong I want that for myself too. But I just want a more fun way to excersise. And I heard on the news that playing a Wi does count as a form as excersising. But my parents won't let me get one because I mistakenly broke my Nintendoe Ds. But it's not like it doesn't work. Please help me! What should I do?
