Written instructions available. A verified 3D demonstration has not been built for this variation.

Source-researched guide. Clinical review is pending.

How to move

Sit with knees bent and hold the ankles (or calves). Lift the feet and straighten one leg, then the other, into a V. Balance just behind the sit bones.
Breathe in, scoop the abs, tilt the pelvis back and roll to the shoulder blades, keeping the V.
Breathe out and roll back up to the balance without the legs dropping.
Pause at the top, then repeat.

Form cues

Keep the V the same shape as you roll.
Start the roll by scooping the abs, not throwing the head.
Avoid: rolling onto the neck, or landing with a jolt.

Practice and cautions

4 to 6 reps (the classical sequence uses 6). A suggested starting point. No trial has tested this move on its own.

As with rolling like a ball: skip it with a neck problem, a sore tailbone or osteoporosis (repeated end-range bending). 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.
