(2) LUNG CELL STIMULATION.
This exercise is designed to stimulate the air cells in the lungs, but beginners must not overdo it, and in no case should it be indulged in too vigorously. Some may find a slight dizziness resulting from the first few trials, in which case let them walk around a little and discontinue the exercise for a while.
(1) Stand erect, with hands at sides.
(2) Breathe in very slowly and gradually.
(3) While inhaling, gently tap the chest with the finger tips, constantly changing position.
(4) When the lungs are filled, retain the breath and pat the chest with the palms of the hands.
(5) Practice the Cleansing Breath.
This exercise is very bracing and stimulating to the whole body, and is a well-known Yogi practice. Many of the air cells of the lungs become inactive by reason of incomplete breathing, and often become almost atrophied. One who has practiced imperfect breathing for years will find it not so easy to stimulate all these ill-used air cells into activity all at once by the Complete Breath, but this exercise will do much toward bringing about the desired result, and is worth study and practice.
(3) RIB STRETCHING.
We have explained that the ribs are fastened by cartilages, which admit of considerable expansion. In proper breathing, the ribs play an important part, and it is well to occasionally give them a little special exercise in order to preserve their elasticity. Standing or sitting in unnatural positions, to which many of the Western people are addicted, is apt to render the ribs more or less stiff and inelastic, and this exercise will do much to overcome same.
