Losing 30 pounds, any exercises?

[victoria]

i need some fun exercises that i can do. im 16, so nothing dull, painful, or boring. things that won't build muscle, but will tone because im a chick. lol. i prefer stuff to do inside, because i dont wanna do it in front of everyone in my neighborhood. haha thanks

im trying to lose some weight in order for summer. how long do you think it will take me to lose 20-30 pounds?
