I read Ronda Rousey's book My Fight / Your Fight earlier this year, and ultimately I recommend that book over this one. They are different books with different purposes, but I read them for the same reason: lady athlete role models. As a lady with relatively new, ongoing athletic goals, I'll admit to needing some role models, even famous ones.
Rousey's book, a straightforward memoir, is the more inspiring and empowering book. It made me want to go out and kick some ass. I think that's what Lindsey Vonn wanted to accomplish with her book, but Strong Is the New Beautiful is rather bland. It sends an excellent message: strength should be admired and strived for just as much as, if not more than, traditional beauty—a sentiment I agree with—but she fails to provide compelling examples from her personal or professional life.
The memoir portions of the book are slight and shallow. They're a footnotes version of how Vonn became an Olympic gold medalist. The nutrition section is very practical, favoring clean eating over dieting; however, it may be too advanced for some readers, especially if diet and nutrition are a struggle. Lastly, the fitness section, while simple, does offer some helpful strength-training exercises for working out at home.
