Just wanted to thank you for the manual that came with the Xtrain series. It came it great handy today. I just followed along in the book (bis & tris) while watching this day's worth of football. No need to get out the DVD and I didn't miss a rep or a snap/play!!! Workout just as effective, too!! It would be a great inclusion for future series, as well, as I could still use it for cardio, too - like doing drills. So thanks!!!
