The fascia is the organ that gives your body its shape. Fascia is plastic, which means it has the ability to change. It will take on the forms that you put it in the most. If you spend a large portion of the day seated in front of a computer with your head and shoulders forward, the front line of your body will likely shorten to help hold you in that position. This puts strain on your back, neck, and shoulders. To help keep your tissues limber and adaptive, try to get up from your desk and move around at least every 30 minutes.
