If you sit for a living like many of the people we see, or even if you just sit at your computer watching cat videos for hours at night, your spinal discs aren't getting enough movement. Regular exercise does not focus on the discs in a way that effectively moves them through their ranges of motion every day. Exercising the discs requires a very isolated motion. We use the Pettibon Wobble Chairs for this in our office. This series of videos by Dr. Burl Pettibon explains the why and how of the Wobble Chairs that are scattered about our office. The videos are short and a bit geeky but I guarantee you will learn something.
