A couple of links for you, too -
Wharton
Active Isolated Stretching video (You Tube)
Matte's book at
Amazon -
Active Isolated Flexibility
You could just look at the video and do fine. The book has whole body exercises with a list of sequences in the back. I ended up taking pics of the lower back/leg sequence stretches and keeping them on my phone so that I don't have to lug a book around. I've got most of them memorized by now, and down to about a 15-20 minute post-run routine depending on how much strength work I do after. My focus is hip stability thanks to a torn labrum in my left hip, which directly contributes to the IT Band issue.
