I lost plenty of sleep over the last three years as I agonized over how to condense complex scientific concepts without sacrificing accuracy. So, needless to say, I was a bit nervous when I found out Dr. Mike Joyner, one of the world’s leading experts on human performance and exercise physiology would review my book. That’s kind of like having your book on football strategy fact-checked by Bill Walsh. (Of course, when I told Dr. Joyner that, he replied: “Don Coryell, or better yet Sid Gillman. Walsh gets way too much credit.”) So I was thrilled to see that Dr. Joyner found my science writing to be accurate, and that he recommended the book highly. In his words: “I recommend this book generally to sports fans, but more importantly this book should also be read by people who are broadly interested how an individual’s biology interacts with their behavior (training), their environment, and their culture.” Check out his review here!
