Posture for a Healthy Spine
Posture is the position in which you hold your body upright against force of gravity while standing or sitting. The posture constantly changes depending on the activity, however no matter what you are doing, there is a way of holding and moving your body that is balanced and efficient. This way is called good posture.
Good posture requires the least amount of muscle activity to breathe well and to maintain an upright position. The feet should be placed comfortably apart, with the weight distributed evenly over both feet. From a front or back view, the shoulders, the hips, and the fingertips should be approximately aligned. From a side view, the ear and the shoulder should be aligned, and that line projected downward should fall in front of the middle of the knee. The back should not be excessively arched. The arches of the feet should be visible without conscious effort.
