If you're looking for a new workout, look no more. Dance Dance Party Party is your new best friend. With no teacher, you can feel free to do what you want, like spin, jump, yoga, interpretive dance - who cares? "It's like being out at a club with your girlfriends without the expensive cover charge (only $5 per class!) and sweaty dudes grinding on you," say its organizers. Classes are at 6:30-8pm every Wednesday at Perceptual Motion Dance Studio (4057 N. Damen Ave.).
