Reduce back pain with active sitting
Back pain is often the result of weak stabilizing muscles. Using a Stability Ball™ as a chair is an effective way to rehabilitate and prevent back pain as it strengthens the deep stabilizing muscles that support the spine. As your joints and muscles react to keep you balanced in a sitting position, those abdominals are fired up, challenging the core while stabilizing the spine.
Keep the blood flowing while you sit
Maintaining balance during active sitting, drives the heart to pump blood a bit faster than sedentary sitting and the blood vessels in the legs and hips open up increasing blood flow further. Better blood flow drives more oxygen to the brain which keeps the mind sharp and focused.
