Researchers at New York University conclude a narrow waist and large hips are optimal for keeping a hoop spinning

Snake hips, good core strength and a willingness to look slightly ridiculous all come in helpful for those wishing to master the art of hula hooping. Now scientists have concluded that an hourglass figure may also be advantageous.

The study, involving gyrating robotic figures of various dimensions, suggests a narrow waist and large hips are optimal for keeping a hoop spinning in a stable position. But those with less curvy physiques may be able to compensate by making larger hip movements at a faster pace, the analysis concluded.
