Depending on your goals, there may be a handful of answers to this important question. The exercises may increase your flexibility, increasing your ability to move the body without pain or limitation. They may help you relax, spending a little time each day focused only on your breathing and forgetting about your stress. They may help your balance, strength, blood pressure or sleep.
At the center of all these motives is the spine, perhaps the single most important communication pathway of our body and mind. We can live without our arms and legs, but we cannot live without our spine. It provides structure, protection and support for our heart, lungs, organs and head.
Almost every signal sent from around the body, from the fingers to the toes, makes its way to the central nervous system by way of the spinal cord. And almost every command about balance, movement or breath also travels via the spine.
So every exercise, whether of the feet, arms, hips or abs is also an exercise of the spine. Even breathing exercises and meditation require communication through the spinal cord as we control our ribs, abdomen and posture. Paramhansa Yogananda called the spinal cord a “lightning rod for the divine.”
Our practices should contain plenty of attention to the health and function of the spinal column (the structural part) and cord (the nervous system part). We should keep the muscles of the spine strong and mobile, as well as doing what we can to protect the bones and discs strong; plenty of forward bending, backward bending and twisting. And we should also keep our awareness on the communicative aspects of the spine: its nerves.
As one of our teachers said: “The arms and legs assist the posture. Every posture is in the spine.”
