Why You Should Go: You loved the '80s: Miami Vice made all-white suits look cool, Madonna inspired a fingerless-glove craze, and above all, you had a slamming body from practicing the moves from "Thriller". So, when you want to get back in '80s era shape, try the fitness craze that's been transforming bods since your favorite decade, with ten classes at Jazzercise Charlotte Fitness Center.

Why You'll Love It: While we loved the 80s, the 2012 version of Jazzercise replaces Sheena Easton with Ke$ha and jazz squares with booty pops for the same (but updated) fat-blasting workout. Each 60-minute session combines hip-hop moves, yoga, Pilates, jazz dance, kickboxing, and resistance training for a fun class that's over before you know it. You’ll walk out having burned mega calories (up to 600 per hour!)

What's the Buzz: Featured in magazines like Shape, Women’s Day, Fitness, People and more, Jazzercise is famous for combining cardio, strength training, and stretching for a head-to-toe, effective workout. And, yes, that was Gwyneth Paltrow you saw sweating it out in an episode of last season's "Glee".
