After reading about muscle imbalances on your web site , and your money back guarantee if the video and book didn't work for me, I thought I've nothing to lose. On a Monday at 5pm I purchased online and on the Friday morning it arrived (that's just 3 days all the way from the U.S.A. to Canterbury Kent England). So I performed the self assessments and started on the exercises, including the specific exercises for sciatica. With in days I was feeling better and after 2 weeks I am feeling really good. It is now 19 days as I write this and I have just been to see my acupuncturist, and she is amazed at my progress. So my next visit is not for another 6 weeks, and the way things are going I probably won't need to go. I am still asking myself how these exercises can make so much difference?? Thank you so much.
