Query: Helped get me moving again

This dvd contains a great set of movements, that have helped me to get lost mobility back. I suffered from -> extreme <- (y'all know what I'm talking about) lower back pain on and off over for years. For less that the cost of a chiropractor visit, here is a routine that for me has been very effective. Though it hasn't made my back feel like brand new, I now move around much better and without most of the pain. Good stuff.
