plow pose

Do this asana slowly and gently. Ensure that you do not strain your neck or push it into the ground.
Support your back on the tops of your shoulders, lifting your shoulders a little towards your ears.
Avoid jerking your body, while bringing the legs down.

Poorva Halasana or the preliminary plow pose is a preparatory asana before you practice full Halasana pose. It is relatively easy to perform.
Shoulder Stand (Sarvangasana) is usually done before the Plow Pose (Halasana) in the Padma Sadhanasequence. To do Sarvangasana, when you lift your legs and hips off the floor, instead of taking your legs 180 degrees over your head, stretch them upwards in the air, so that you come up high on your shoulders, supporting you back with your hands. Halasana goes hand-in-hand with Sarvangasana.
Bridge Pose (Setu Bandhasana) is another asana that can be done before Halasana.
