Jazzercise is a fitness franchise company founded by Judi Sheppard Missett in 1968 and headquartered in Carlsbad, California, United States. The franchise's name is a portmanteau of "jazz" and "exercise". Jazzercise combines dance aerobics, strength and resistance training with popular music for a full-body workout. The company currently has over 8,300 franchisees worldwide in 32 countries. Early history Judi Sheppard Missett created Jazzercise in Evanston, Illinois in 1968 as a student at Northwestern University. She was teaching at a dance studio and noticed her classes had high dropout rates. Realizing students were attending for physical fitness and not for performance, Shepard Missett began to hold "just for fun" classes that began with a jazz warmup. These classes were eventually renamed "Jazzercise". Jazz dance came relatively late into Missett's life—in 1966, just after she graduated from Northwestern University with a degree in theater and dance. She signed up to study with renowned jazz choreographer Gus Giordano at his Evanston studios. Growth and franchising Sheppard Missett's family moved to Carlsbad, California, where she taught classes in local rec centers. Jazzercise quickly took off in San Diego and Sheppard Missett trained new instructors herself. Many of those first instructors were in military families, so as they moved around the country, and the world, new populations were continually introduced to the program. Initially using VHS videos, Sheppard Missett was able to train franchisees from a distance and began to sell franchise rights for Jazzercise studios across the country. In addition to the franchised classes, Sheppard Missett produced recorded Jazzercise programs for home use, starting with an LP entitled Jazzercise in 1981 which was certified gold in 1982. Sheppard Missett produced a second LP in 1982 entitled More Jazzercise and released her first VHS Jazzercise workout called Let's Jazzercise a year later.
