Your spine is made up of a series of interlocking bones with small cushions in-between each joint socket. The structure of your spine is what allows you to move freely from side to side. Every time you crunch your abdomen by bending forward, or lean to one side or another for a deep stretch, those little vertebral bodies move with you, keeping you comfortable and your back strong. Without cushioning in between each of those sockets, the bones would rub against one another with every movement, and this would be incredibly painful.
