Disco
Dance

In the early years, dancers in discos danced in a "hang loose" or "freestyle" approach. At first, many dancers improvised their own dance styles and dance steps. Later in the disco era, popular dance styles were developed, including the "Bump", "Penguin", "Boogaloo", "Watergate", and "Robot". By October 1975 the Hustle reigned. It was highly stylized, sophisticated, and overtly sexual. Variations included the Brooklyn Hustle, New York Hustle, and Latin Hustle.

During the disco era, many nightclubs would commonly host disco dance competitions or offer free dance lessons. Some cities had disco dance instructors or dance schools, which taught people how to do popular disco dances such as "touch dancing", "the hustle", and " the cha cha ". The pioneer of disco dance instruction was Karen Lustgarten in San Francisco in 1973. Her book The Complete Guide to Disco Dancing (Warner Books 1978) was the first to name, break down and codify popular disco dances as dance forms and distinguish between disco freestyle, partner, and line dances. The book topped the New York Times bestseller list for 13 weeks and was translated into Chinese, German, and French.

In Chicago, the Step By Step disco dance TV show was launched with the sponsorship support of the Coca-Cola company. Produced in the same studio that Don Cornelius used for the nationally syndicated dance/music television show, Soul Train, Step by Step' s audience grew and the show became a success. The dynamic dance duo of Robin and Reggie led the show. The pair spent the week teaching disco dancing to dancers in the disco clubs. The instructional show aired on Saturday mornings and had a strong following. Its viewers would stay up all night on Fridays so they could be on the set the next morning, ready to return to the disco on Saturday night knowing with the latest personalized steps. The producers of the show, John Reid and Greg Roselli, routinely made appearances at disco functions with Robin and Reggie to scout out new dancing talent and promote upcoming events such as "Disco Night at White Sox Park".

In Sacramento, California, Disco King Paul Dale Roberts danced for the Guinness Book of World Records. He danced for 205 hours, the equivalent of 8½ days. Other dance marathons took place afterward and Roberts held the world record for disco dancing for a short period of time.

Some notable professional dance troupes of the 1970s included Pan's People and Hot Gossip. For many dancers, a key source of inspiration for 1970s disco dancing was the film Saturday Night Fever (1977). Further influence came from the music and dance style of such films as Fame (1980), Disco Dancer (1982), Flashdance (1983), and The Last Days of Disco (1998). Interest in disco dancing also helped spawn dance competition TV shows such as Dance Fever (1979).
