It is one of the most important yoga pose or asana, particularly for the young people because full-scale shoulder stand can pose problems for the age category beyond thirty or so.
For them who are having problems in neck and shoulder regions should avoid this one and go for Half Shoulder Stand Pose(Ardha- Sarvangasana). You can take the help of the Wall or somebody else if you have problem printing as a beginner.
REMINDER :: Practice Fish Pose ( Matsyasana ) and Plough Pose ( Halasana ) after Shoulder Stand definitely. Practice of Fish Pose is mandatory after Shoulder Stand Pose, in case you omit Plough Pose. Practice Shoulder Stand four times of thirty seconds each with Corpse Pose of thirty seconds after each practice of shoulder stand (of thirty seconds ).
