For much of the twentieth century, sweating was considered "unladylike" and girls grew up believing physical exertion would cause their uterus to "fall out." It was only in the Sixties that, thanks to a few forward-thinking fitness pioneers, women began to move en masse. In Let's Get Physical, journalist Danielle Friedman reveals the fascinating untold history of contemporary fitness culture, chronicling in vivid, cinematic prose how exercise evolved from a beauty tool pitched almost exclusively as a way to "reduce" into one millions have harnessed as a path to mental, emotional, and physical well-being. Ultimately, it tells the story of how women discovered the joy of physical competence and strength--and how, by moving together to transform fitness from a privilege into a right, we can create a more powerful sisterhood.
