After pranayama, get set to do the physical exercises or yogasanas. The following exercises help in curing constipation.

1. Sit on your haunches with the heels of your feet touching the backside of your upper thighs. Clench your fists tightly keeping the thumb of each hand tucked underneath the remaining four fingers. Take a deep breath, exhale, and then hold your breath at this posture. While in this posture, place your clenched fists against either side of your navel, such that the folded thumbs touch your stomach. Now bend forward, holding your head up. The fists will press against your stomach while you are holding your breath. Hold yourself in this position till you feel breathless and need to inhale. Now get up while still sitting on your calves. You can repeat this exercise three to five times, or even eleven times if the constipation is severe. Once you are done, come back to your cross-legged position, close your eyes, and then relax.
2. Lie down on your back, bend one leg inwards towards your stomach and hold it with both of your hands. Press this leg against your stomach as much as possible. At the same time, lift your head off the ground and try touching the knee of this leg with your nose. Remain in this posture for 20 to 30 seconds. Repeat the exercise with the other leg. While doing this you may find gas escaping through your anus; do not feel embarrassed; the aim of this exercise is to expel gas from the body.
3. Next, perform the exercise given above using both the legs simultaneously.
4. While holding both of your legs and touching your knees with your nose, as described in postures 2 and 3 above, start rolling on your back with your head up and your feet down. Follow this by reversing the position, i.e. having your head down and your feet up. Hold the legs tightly against your stomach and roll in a rhythm; this expels most of the gas trapped in your digestive tract.
5. Now sit up. Stretch your legs while joining them together. Then, cross your right foot over the left knee,while keeping the left leg straight Place your left arm across your back. Now, try to hold your left foot with your right hand while keeping the left leg straight. Hold this posture, turn your head anti-clockwise and try to look behind you.
6. Repeat this posture the other way round. Hold these postures for two to three minutes each time you do it. You can repeat these postures the exercise five to ten times.
