Sarah Palin is reportedly working on a fitness book. The former governor and reality TV star told People the news via email.

She wrote: “Our family is writing a book on fitness and self-discipline focusing on where we get our energy and balance as we still eat our beloved homemade comfort foods!…We promise you what we do works and allows a fulfilling quality of life and sustenance anyone can enjoy.”

Palin did not give details about which family members are involved in the books, what publisher will release the book, or when the book would be released. Palin is the author of two books — the 2009 title Going Rogue: An American Life and the 2010 release America by Heart: Reflections on Family, Faith, and Flag, both HarperCollins releases.
