Note: Always do this on an empty stomach and not more than twice per day.  This exercixe is said to adjust the acid–alkaline balance in the stomach, but it must be done regularly without missing a single day.

Posture: Sit in Easy Pose with hands on the knees.

Breath and Movement: Make a beak of the mouth and drink as much air as you can into the stomach using short, continuous sips, as if you were swallowing. Pull in and hold. Roll the stomach to the left, when the breath has been held in for half its maximum time, reverse the direction to the right.

Continue rolling the stomach as long as possible with Neck Lock applied. When the breath can be held in no longer, straighten the spine and exhale slowly (not powerfully) through the nose.

This exercise is said to strengthen the heart.

Posture: Sit on the heels and touch the forehead to the ground. Place the hands palm up by the hips.

Movement: Imagine that there is a big, 100-pound tail coming off the end of the spine and wag it as if trying to make it break the wall. Move the hips left and right–a few inches–as if the tailbone traces out a “U”; this will churn the navel and the lower abdomen as you move.
