Kapalbhati is a part of Pranayam kriya that has been in vogue ancient India where one forcefully exhales rapidly and in short bursts. Practitioners of yoga say it helps in cleaning the lungs and in exercising the abdomen muscles. It is therefore recommended for reducing tummy fat. This exhalation exercise can be practiced by either sitting cross-legged on the floor or even in a chair. The air is exhaled forcibly and in short bursts. This process is further helped by thinking that by exhaling this air one is cleaning the brain of its pollutants. The reflex action of this forceful exhalation then tones the abdomen muscles and also cleans the lungs.
