How to do it

Follow the steps in order. Move in a comfortable range unless your provider said otherwise.

  1. Lie on your side with knees bent and heels stacked.
  2. Keep the pelvis stacked and open the top knee like a clam.
  3. Do not roll the pelvis backward.
  4. Lower with control and repeat, then switch sides.
