The crocodile position teaches you how to breathe with your diaphragm to help relief abdominal cramps. Lie on your stomach with your toes pointing either inward or outward. Position your elbows and lower arms so that when your head rests on the arms, your chest does not touch the floor. When inhaling, you should feel your abdomen reach the floor. When exhaling, your abdominal muscles should relax and your abdomen lift off of the floor. As a part of meditation, this exercise can be performed for about 15 to 20 minutes, and as part of an exercise routine, for at least 5 minutes.
Another technique for this exercise is to lay on your back and place a book over your abdomen. Slowly Inhale and the book should rise up and exhale and the book should lower. As a part of meditation, this exercise can be performed for about 15 to 20 minutes, you can also practice this exercise as a five minute breathing break throughout the day.
