In the late 1960s, Air Force surgeon Dr. Kenneth Cooper was evaluating military fitness plans when he realized that aerobic activities, what we now call cardio, like running and cycling, was the key to overall physical health. His 1968 book Aerobics launched the aerobics revolution that followed, as he inspired women like Jacki Sorensen and Judi Sheppard Missett to combine dance with exercise, creating Dance Aerobics and Jazzercise in the process.  
I’m joined on this episode by Dr. Natalia Mehlman Petrzela, Associate Professor History at The New School and author of Fit Nation: The Gains and Pains of America's Exercise Obsession.
