1. Keep your hands by the side of your body in a supine position. While inhaling, raise both your legs to 90 and bend them at the knees.
2. Make a finger-lock with both your hands around them, a little below the knees. While exhaling, bring your thighs close to the chest by contracting the abdominal muscles. Maintain this posture for a few seconds.
3. Then return to the original posture in the reverse order as Ardha Pavan Muktasana. Repeat the asana three to four times.
Benefits & Precautions:
Pavan Muktasana strengthens the abdominal muscles and liver, spleen, pancreas and stomach. It eases excess gas from the abdomen. Persons suffering from constipation must do this after drinking lukewarm water for proper evacuation of bowels in the morning. Pavan Muktasana is the best asana to expel gas by compression of the abdomen.
