Posture, More than about appearance

The average head weighs roughly 11 lbs. When your head is stacked directly over your cervical spine your muscles and soft tissue (tendons, ligaments and fascia) can easily stabilize your head while allowing for movement in all three planes of motion. Although once you start to develop a forward head tilt everything changes.

Your neck and upper back muscles are now constantly contracting to keep your head from tilting even further forward. This can lead to chronic neck and shoulder pain. Your shoulders start to round forward making you prone to rotator cuff impingement. The S curve in your spine now becomes a C curve putting additional pressure on your cervical as well as lumbar discs. The curve in your thoracic becomes exaggerated and leads to a loss of extension through your mid/upper back region. The negative implications from these three adaptations are too numerous to list.
