Stand up straight! Pull your shoulders back! As children, we were told to have good posture. Yet we were seldom taught effective ways to accomplish this. Indeed, we were often not even told just what good posture is.
The consequences of this information gap can be seen all around us: stiff necks, shoulders hunched forward or pulled tightly back, restricted breathing, and tightness in the thighs, legs and ankles. Backaches, headaches, and other painful symptoms are often the unfortunate result.
