At Spinarella, whirling instructors elucidate the art of gyration during lively calorie-blasting pole-fitness classes and parties in their all-female fitness studio. Each of their one-hour classes is capped at 15 ladies to ensure adequate bonding between pole and dancer through small talk and shared admiration of neoclassical architecture. Students of all shapes and sizes can also perfect their come-hither moves during classes that focus on off-the-pole dances such as Jiggle, Lap Vegas, and Sexible Flexible.
