Without belly dancing classes, locomotion addicts must chain their hips to the pendulums of grandfather clocks, waiting patiently until Middle Eastern cabaret classics are played at the stroke of midnight. Experience safe, supervised stomach contortion with today's Groupon: for $20, you get two drop-in belly dancing classes at the World Dance and Music Center in Pawtucket (a $40 value). Your Groupon may also be used toward hula or pilates classes.

The seasoned squad of musicians and stomach-swivelers at World Dance and Music Center can fortify the fitness and liberate the shackled hips of all body types and age levels. The multi-talented and multi-lingual Lola is an accomplished dancer who infuses her classes with emotion and an authentic Middle Eastern sensibility. Classes for all skill levels take place Monday, Tuesday, and Wednesday evenings. Beginners Bellydance slows down the pace to cater to the never-danced, while Bellydance for Performance is geared toward the experienced motionista, covering proper costuming and stage presence. Bedecked with hardwood floors, a wall full of mirrors, and an elevated stage, the 3,600-square-foot studio gives ample space to promote tummies' uninhibited fluttering.

Celebrate the power of undulation, and siphon that power into your body for enhanced posture, endurance, and core-muscle strength. Like the waves of the ocean or silk bloomers billowing on the clothesline, so will your body ripple and roll in the ecstatic freedom of undulation. Though the sensuous belly rolls, hip drops, and shoulder shimmies appear effortless, you'll isolate core muscles to perform each gesture with precision and hone your body into lean, serpentine shape that's perfect for catching field mice or navigating gutters.
