Hooping (also called hula hooping or hoop dance) generally refers to manipulation of and artistic movement or dancing with a hoop (or hoops). Hoops can be made of metal, wood or plastic. Hooping combines technical moves and tricks with freestyle or technical dancing. Hooping can be practiced to or performed with music. In contrast to the classic toy hula hoop, modern hoopers use heavier and larger diameter hoops, and frequently rotate the hoop around parts of the body other than the waist, including the hips, chest, neck, shoulders, thighs, knees, arms, hands, thumbs, feet and toes. The hoop can also be manipulated and rotated off the body as well. Modern hooping has been influenced by art forms such as rhythmic gymnastics, hip-hop, freestyle dance, fire performance, twirling, poi, and other dance and movement forms.
