Query: Video Not for Everyone

I bought this video after rupturing a disc in my lower back. I was unable to do any of the exercises, as they caused me further discomfort. I would not recommend this video to anyone who has moderate to severe back pain because the exercises are too advanced for a person in this condition. However, if you are almost recovered from a back problem, or are only experiencing mild back pain, this video will teach you exercises to help improve your muscle strength. It also offers some very simplistic "how-to's" for daily activities such as bending, loading the dishwasher, etc., in a way that will not reinjure your back. These tips are really common sense ideas that will not greatly benefit anyone who is already living with back pain. Finally, I was disappointed by the video quality--it looks as if it were filmed by a low-end home video camera.
