Owner and nationally renowned instructor Stephanie Babines and her team guide students toward increased strength, confidence, and flexibility in empowering, female-only classes. Instructors impart pole-dancing basics in Pole 101, helping new dancers to tone and trim while learning 20 beginner moves. The Poleitude (Pole Tricks with Attitude!) class focuses on technique to help slinky students to fine-tune eye-catching poses, transitions, and sexy spins without the risk of injuring themselves, and the Pole Conditioning class readies students to tackle more advanced moves or carousel race horses. Students' feather boas will get as much of a workout as their lower bodies in the stiletto-heeled Burlesque class, and equally intensive Belly Dancing and Hoop Dancing sessions help to slim down shimmying forms. A healthy sampling of yoga, Pilates, Zumba, and other dance and fitness classes fills the packed schedule.

The swank studio features five poles, a mirrored stage, and padded cardio flooring to cushion sassy Zumba dance moves and gravity-foiled pole spins. Instructors provide free weights and other fitness supplies, and a wardrobe of dress-up clothes and accessories lets students experiment with flirty ensembles or perfect Liza Minnelli impressions. Dressing rooms feature an arsenal of towels, lotions, perfumes, and cosmetics for students who wish to freshen up.
