The workout class uses ballet and yoga-inspired movements designed to use your own body weight to develop long, lean muscles and the flexibility of a dancer. And for women who can't make it to Austin's classes in New York, she offers a Fluidity kit which includes a bar, instructional DVD and a nutrition guide.

As I walk up to the studio, Austin warns me, "This class is going to be challenging for you. Don't feel bad if you can't do everything. I've got a lot of regulars that have been coming a long time." And many of her students do look like regulars, lean and toned. But thankfully there's a range of ages and sizes, which makes this newcomer feel a little bit better.

The hour-long workout consists of a series of stretches and repetitions of fluid movements all centered on the bar. No muscle is left untouched. After each exercise, we stretch out the muscles to keep them long and lean. I suddenly have aching muscles that I didn't know existed until now.

Because of Austin's unusual combination of a background in kinesthetic anatomy and physiology of motion as well as a previous stint as a VH1 VJ, she'll keep you simultaneously informed and entertained. She developed her program to reflect its principles; she gives informed, easy-to-follow explanations behind each exercise. You feel like you're learning more about your body as you're working on it. Her recurring theme is muscle balance, which only can be perfectly achieved by using your body weight for resistance, and not isolating muscles as other fitness routines — such as weight lifting and Pilates — routinely do.

Even after my first class, when my form was a little shaky, I felt my muscles were introduced to a new way of performing and maybe if I kept it up, I could achieve the dancer's body I longed for — itchy tights not included.
