Types of breathing exercises in Hatha Yoga include three forms of breathing which are quite popularly known among the Yogis. The first is the well-known Yogi Cleansing Breath, to which is attributed much of the great lung endurance found among the Yogis. The Yogis usually finish up a breathing exercise with the Cleansing Breath. It is said that the Yogis have a favourite form of breathing which they practice when they feel the necessity of ventilating and cleansing the lungs. They conclude many of their other breathing exercises with this breath.
