Viparita Karani,the Inverted Pose-variations in Sarvangasana

In Sanskrit, `Viparita` means inverted and `Karani` means an action, and the asana derives its name from the posture that involves inverting the position of the body, placing the head at the bottom and the legs on top.

Viparita Karani, or Inverted Action Pose, is an intermediate yoga asana, in which the practitioner lies down on a mat and lifts the legs perpendicular to the ground. Yoga practitioners consider it as a pose that improves pelvic circulation and increases the blood flow to face, neck and thorax and improves the functioning of adrenal, pituitary and thyroid glands. It is also referred to as legs-up-the-wall pose.

How to position the pose:

• Practitioner has to sleep straight on mat,with hands stretched above neck.
• Next step,lift up your leg 30 degree from ground level,then 60 and finally 90 degree this will test ur capacity and strengthens your abdominal.
• Place both of your hands straight and hard support weight with fre arms.
• The weight of the body is, thus, raised and supported by stiffening the arms that are still stretching along the ground.  
• Then lift your hip up and support your hip-bone with both the hands and keep leg straight. 
• Here the trunk does not make a right angle with the ground as in Sarvangasana, but simply takes an upward curve. 
• The chest does not press against the chin, but keeps itself away from the chin. 
• The eyes are either closed to concentrate the mind upon a particular part in the body or are kept fixed upon the toes.

 Youngsters can do anything but what about the people aged and who struggle even to raise a single leg up in air so for aged poeple or whom wants to learn without strain try this technic.

Raise your arms straight and keep breathing deeply.

Note:Keep in mind that you are doing yogasana not any other simple exercise.So,keep breathing as long as you can,if you held your breath while in action then the respected muscle will get strain or sometimes it may effect adversly.
Another main thing to keep in mind while lifting your legs do not forget to breath,in yogasana positions may be like anything but while lifting any parts of your body you must and while leaving down exhale.
