Though it gets its name from its pole-fitness classes, Polestars is hardly a one-trick pony. True, many guests might be attracted to the way the pole-dance sessions, taught with an artistic and athletic approach, build strength, flexibility, and sensuality through fun and inhibition-shattering routines. But they're just as likely to visit for the bounty of other unorthodox fitness classes. In Fly Gym, for instance, students support themselves on ceiling-mounted fabric slings or with their own powers of levitation as they perform yoga poses, strength exercises, and even traditional pole-dance moves high above the ground. Kangoo Jumps sessions fit students with specially designed bouncing boots for a low-impact, gravity-defying workout, and Hoopnotica helps participants hone body awareness and rhythm savvy with the simple aid of a hula hoop. Whatever class they choose, guests can rest their minds knowing they're attending an environmentally friendly fitness studio: the lights are energy efficient, the dance floor is made of sustainably grown bamboo, and the cleaning products are nontoxic and biodegradable.
