As you can see, stretching in all of its various forms is extremely important for the body. Paschimottanasana is associated with back health and it aids the stretching of the back, but with some small modifications to the angle of the pose, it becomes a wonderful aid to help your digestive process. This pose helps you push new blood into the organs by using force against your body. Simply fold yourself against a pillow and hold for a few seconds. When you release, the blood will flow back into your organs.
