Remember _the inspiration must be slow and deep, the expiration sudden and complete_.

Practise this preliminary exercise for not more than ten minutes each morning for a week.

The second week hold the breath six seconds, instead of four, and gradually increase the time, without overdoing.
While, for a novice, the exercises may be taken at first in bed, this is but a preliminary to their practise standing in easy poise as directed in the preceding section.
Exercise II SLOW INHALATION WITH SUDDEN EXPULSION Inhale as in I; hold the breath four counts (seconds) or more; then expel the air vigorously in one breath through the wide open mouth.
The beginner is often helped in acquiring a deep breath by slowly sipping breath.

Therefore as a variant to Exercise II practise: Exercise III SIPPING THE BREATH, WITH QUICK EXHALATION Through the smallest possible opening of the lips, while mentally counting, inhale very slowly and steadily; hold two to four counts, then expel the air all at once through the wide open mouth.
Exercise IV FOR RIB EXPANSION To more completely arouse dormant muscles that should play an important part in breathing, place the hands against the sides, thumbs well back, take, through the nostrils or the slightly parted lips, six short catch-breaths, moving the ribs _out at the side_ with each catch-breath.

Hold the breath two counts, and exhale through the mouth with six short expiratory puffs, drawing the ribs _in at the side_ with each puff.
Exercise V SLOW INHALATION WITH SLOW EXPIRATION Inhale as in I, while mentally counting one, two, three, four, etc., until the inhalation seems complete.
