Hm. I listened to a few interviews with the author on my favorite podcasts, which made me think, wow, I really have to read this book. I don't know. I sort of stalled out - maybe she talked about the best part of it in there interview. It didn't really get to the parts I was most interested in till the very end of the book. And it identifies problems with access to excercise but stops short of imagining or mentioning any sort of solutions that any group may have proposed. But it is a pretty good history of excercise and changing American relationships with it throughout our history, so four stars. 

As a (female) jiu-jitsu black belt, I waited for her to mention my sport and all I got was this:

"In the twenty-first century fitness "bro culture" disseminated in weight rooms, in jiu-jitsu studios, and through supplement-sponsored YouTube channels, fellow historian and gym rat Patrick Wyman writes, men celebrate pain, might, and brawn as they figure out "what it means to be a guy.""

Ick.
