Thanks for the compliment. I'm glad you've found the exercises helpful. Ultimately I put together this website to help people and other physiotherapists looking for exercises. I should advise all the readers that this particular exercise is a good stretch for most people, but if you suffer from ailments such as facet osteoarthritis, rheumatoid arthritis, spondylolithesis, spondylolysis, spinal stenosis, or other condition, you should seek advice from your physiotherapist before attempting it.
