Title: Not good for a bad back!
Review: Apparently, this video is for people who already have a strong and healthy back. I bought it hoping to use it in conjunction with physical therapy for a bulging disk -- it made my back hurt a lot more! I only did the first 20-minute session, but that was plenty. It had a lot of twisting and bending, which my physical therapist told me is exactly wrong for me. I wish I had never bought it. Anyone want a used copy?
Is the review positive or negative?
