The spine has bones and cartilage disks that are very sensitive to changes in posture. Much of the back pain one has in their older years stems from sedentary lifestyles and back posture. Bones begin to shape themselves in a way that becomes accustomed to the bad back posture one creates throughout their life, compressing the vertebrae in the lower back and leading to back pain. While this sounds bad, the good news is that back posture is one of the most easily correctable problems in the body. Correct back posture is achievable with the Posture Pump Elliptical Back Rocker by lifting and separating the back joints to their old positioning. This reinforces the spine's natural shape and promotes joint lubrication, joint nutrition, flexibility and proper back posture. With the Posture Pump Elliptical Back Rocker, you can restore your back posture to the way it's supposed to be without intense physical therapy sessions.
