Monday is usually intestine exercise day at the Dahn Yoga center in which I work. Intestine exercises are a little strange for people at first. I have grown to love them. You can do them anywhere at anytime. To do them you move the muscles of your lower abdomen toward your back, as if there was a string attached to your navel pulling it back. Then you push the muscles out as far as you can. It is like giving your abdomen a massage and can help conditions such as shoulder tension, coldness in your abdomen, and constipation. Try them and share your experience here!
