Ecdysiast, a modern pole-dancing studio that derives its name from ancient Rome, comingles the sleek techniques of modern fitness with the atavistic impulses of dance, resulting in a fun, social, and physical exhibition of the body’s beauty. A staff that includes certified personal trainers instructs a schedule of classes to accommodate most skill and fitness levels. During a one-hour class of fewer than seven, pupils position themselves before the studio’s floor-to-ceiling mirrors—cut at intervals with white, flowing drapery—to gaze at their reflection staring back at them as it sidles next to their own, individual, 16-foot golden-hued pole. The introductory Taster class dips newbie toes into the rippling waters of pole dancing with beginner moves, choreography, and floor work. At the instructor’s behest, students in the eight-week course will spin, climb, invert, and plane their bodies parallel to the ground in an act of self-levitation unattainable without the use of hundreds of helium balloons. The 90-minute party class packs similar routines and equal energy, but caters to the custom needs of the group, be they bachelorette, birthday, or a girls' night out.
