Query: Excellent content-Kindle version

I have the paperback version of this book and it has excellent content for developing a stretching program based on your individaul situation. I bought the kindle version so i could have it with me whle i travelled. The only complaint is the diagrams and pics were scanned poorly. They are still readable, but i suggest downloading a sample to see if that will bother you.
