TimAnacortes, WashingtonAdd specifity to any running program This book complete's any running book collection. It goes in depth into the biomechanics of running, specific weight training exersizes for breakthrough running, and specific stretching for runners. This book covers the information that most other books only breifly skim over. The knowledge that Michael Yessis shares in this book could be eaisily added to any running program, to make you a faster, and more efficient runner. I would reccommend this book to anyone who is serious about running and looking to add more specifity to their running program. If you want to run faster, and farther without getting injured this is a book for you.
If you are a casual runner who is happy and not interested in making running a top priority in your life, then I would personally skip this book. If you are "into" running and seeking a deeper understanding of what the mechanics of the run are and how to improve your run, then I cannot see how this book would not help you.
