Were you ever able to hula hoop? If you could never get it right, your shape may be to blame: Researchers from New York University’s Applied Mathematics Laboratory found that body type plays a big role in keeping the hula hoop moving. In order for the toy to work, hoopers must have hips and a defined waist. When using a straight cylinder shape, the hoop always fell. When it came to a cone-shape, the hoop traveled too far up or down. For a successful spin, try to keep the hoop just below the narrowest point of your waist. “Our results might explain why some people are natural hoopers and others seem to have to work extra hard,” Leif Ristroph said.
