Our spine houses and protects our spinal cord. Structurally, it keeps us upright and bipedal. Our spinal strength and mobility is why we do Pilates and movement. I will be specifically focusing on the mobility of the spine since I am grasping at such a broad and complicated subject. Limitations of that mobility depend on 1, the individual design of our spine (no two spines are alike) and 2, the possibility of stiffening with arthritis or stenosis as we age. What’s interesting to observe is the vertebral shape and size of the cervical, thoracic, and lumbar, which dictates its movement capabilities. In between each vertebrae are little pillows called discs, which absorb shock and provide space between. What’s that jargon? If you haven’t met your spine by now, I think it is time. Let's take a tour.
