Hula Hooping is no longer just for that cool second grade girl [re:me] and topless woman listening to EDM while "high on life" [re:shrooms]. In fact, it's the latest abdominal-toning fitness fad. Not to worry, no reason to head to your local park and risk a potential child endangerment charge, studios like GrooveHoops and The Art of Fitness offer all the hula hooping classes you never knew you needed.
