MaDonna Grimes
MaDonna Grimes was an American choreographer and personal trainer who became well known for her workout videos in the late 1990s and early 2000s. In the mid-1980s Grimes began teaching a class called "Cardio Hip Hop" in New York City. Although hip hop dance dates back to the 1970s, Grimes has been celebrated as a pioneer for her work presenting hip hop dance in a fitness context as opposed to a performance context. History
