Jazzercise is a dance fitness franchise company founded by Judi Sheppard Missett in 1969 and headquartered in Carlsbad, California. Jazzercise combines dance, strength, and resistance training with popular music for a full-body workout. The company currently has over 8,300 franchisees worldwide in 32 countries.
Judi Sheppard Missett created Jazzercise in Chicago, IL in 1969 as a student at Northwestern University. Sheppard Missett was teaching at a dance studio and noticed her classes had high dropout rates. Realizing students were attending for physical fitness and not to become highly technically proficient in dance, Shepard Missett began to hold “just for fun” classes that began with a jazz warmup. These classes were eventually renamed “Jazzercise.” [[Jazzercise#cite note-2|  ]]
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. [[Jazzercise#cite note-3|  ]]
