Kapalbhati pranayama is a type of breathing exercise
that helps you rid of various ailments over a period of time.
"kapal" means forehead and "bhati" means shining. Eventually, kapabhati should bring about a glow on the face of the practitioner. Kapalabhati is done in a sitting posture. Focus on "exhaling". Inhale as normal. Exhale and simultaneously contract the abdomen muscles with each exhale!
