If you're the edgy type, then popular music has probably been the worst part of your workout experiences. It's a lot easier to stay motivated if the music appeals to you. Punk workouts usually feature the music of the classic punk era, so you can stay in shape with bands like The Ramones, while wearing your best cut-up sweatshirts and ripped fishnets. Be warned: the music is super-fast, so it's not for wimps.

Striptease Class/Pole Dancing

Between the sweat, the workout clothes and the messy ponytails, most women feel distinctly un-sexy in a workout session. With the new fitness classes based on stripper moves, you can feel hot (and not just in temperature) while you get in shape. Sure, you might giggle at first, but you'll eventually feel confident enough to practice your new moves for a special person at home, and a workout that you want to practice on your own is priceless.

Yoga Plus

It's not been that long ago that yoga went mainstream, with millions of people discovering the combination of peace of mind and increased flexibility that it offers. Now you can take yoga in almost any conceivable form from cardio power yoga workouts to yoga/pilates combos. Some cities are offering unique twists on the ancient method by offering versions like disco yoga and rock and roll yoga, so you can easily find one to suit your style.
