For much of the twentieth century, sweating was considered unladylike and girls grew up believing physical exertion would cause their uterus to literally 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 hidden history of contemporary women's 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 strength and competence—and how, by moving together to transform fitness from a privilege into a right, we can create a more powerful sisterhood.
