Roll onto your back, and inhale to hug the right knee in to your chest, and then rock your knee from side to side to help massage your abdominal organs and get things moving for a few breaths. Switch legs, hugging the left knee in.
Then, hug both knees into the chest, rocking from side to side. Release the knees away from your belly, lowering the toes to the floor for a few seconds. Repeat a few more times.
