Well, I -really- need a way to get some exercise (which is impossible at home indoors because I'll disturb my downstairs neighbours, and outside because the neighbourhood kids are jerks who gang up on people just going for a run), and my parents won't pay for... well, anything but a stereotypical "girl" activity, really, so I've been considering taking dance lessons, but the one ballet lesson I took... was bad.

What are the other main styles of dance (that would be easy to find lessons for...) , especially the more fast-paced ones?
