How to perform

Setup

Lie on your side. Prop yourself up on one forearm with the elbow directly below the shoulder. Lift the hips so the body forms a straight diagonal line from head to feet.

Hold for the prescribed duration. Switch sides.

Common mistakes

  • Hips dropping.
  • Hips drifting forward or back.
  • Holding the breath.
  • Going too long too soon.
  • Not switching sides.
