The practitioner lies on the floor, lifts the legs, and then places them behind the head. Experienced practitioners may enter Halasana from a standing position by tucking chin to chest, placing hands on the floor, walking the feet towards the hands and bending at the elbows to lower shoulders to the floor.
This asana can put significant strain on the cervical spine, which does not normally undergo this type of stress, and can cause injury if not performed properly.
Practicing this pose without leg support can lead to injury. To provide support for the legs, practitioners may use props such as blocks. As alternatives, simply lying on the back and raising the legs into a hamstring stretch, or doing a seated forward bend may be appropriate.
