Title: Purchased for Exercise Ball Class
Product review: I am a certified group fitness instructor. I purchased this book in order to prepare to teach a weekly one-hour exercise ball class. This book is excellent because it offers information about progression (the order in which to perform specific exercises). It also offers suggestions for "5-minute total core blasts," if you have limited time on a particular day. The descriptions and photos provide all of the details you need to get started...and get a great core workout. I definitely recommend this book.
