Query: Marathon Runner Must Have

This dvd is exactly what I needed. Christine understands different problem areas for runners because she is an experienced runner.I have difficulty with my back and hips/IT band and since doing this practice, my hips have noticeably improved. The dvd is easy to follow.Many days I do not have the time to spend over an hour on Yoga but the practice is broken up on the main menu. You can either do the whole practice or pick and choose which sections. This is very convenient and probably why I've stuck with it.After completing six marathons, I realized that it was time to really start listening to my body and it has responded well to Yoga for Runners.
