Query: Skip this book and buy the original by Aaron Mattes

Skip this book and choose "Specific Stretching for Everyone" or "Active Isolated Stretching--The Mattes Method" by Aaron Mattes, the guy who first developed these techniques. His site at http://www.stretchingusa.com has more info on these stretches.The exercises and the narrative descriptions in the Wharton book are copied almost verbatim from Mattes' original book--nothing new or helpful is added other than some self-promoting anecdotes about athletic successes--and Mattes' original book has clear and helpful photographs, unlike the amateurish and confusing line drawings in the Wharton book. Mattes' book also includes detailed stretching routines for upper/lower body, neck/shoulders.
