How to move

Sit with the legs crossed and the knees drawn in, holding the feet. Balance behind the sit bones.
Breathe in and roll back to the shoulder blades; uncross and cross the legs the other way.
Breathe out and roll forward, over the knees.
Classical form only: rest the crown of the head on the mat very lightly. It is about stretching, not pressing, and most teachers leave it out.
Roll back and repeat.

Form cues

Roll back to the shoulder blades only.
Keep the shape round and small.
Avoid: putting weight on your head, or rolling onto your neck.

Practice and cautions

4 to 6 reps. A suggested starting point. No trial has tested this move on its own.

Avoid it with neck or spine injuries; master rolling like a ball and the seal first. Never do the head touch on a hard surface. Avoid it with osteoporosis. This is movement education, not an assessment or treatment prescription. Stop for sharp or increasing pain, dizziness, numbness or tingling; seek individual guidance for symptoms, injury or restrictions.
