When people think of the spine, they usually imagine a rigid structural frame designed solely to hold us upright. In clinical reality, your spine is a dynamic neuro-mechanical structure. Its primary evolutionary role is not just weight-bearing, but the physical protection and mechanical support of your central nervous system: the spinal cord and exiting nerve roots.

We tend to measure physical activity in superficial terms, calories burned, miles logged, or muscle built. But from a neurological standpoint, exercise is much more than a metabolic tool. Every time you move a joint, contract a muscle, or change position, your body generates a massive pulse of sensory information that travels up the spinal cord to the brain.
