School of Yoga explains nauli-kriya (Rectus Isolation)

Hatha Yoga Pradeepika on nauli-kriya;

Ch 2 v 33: Sitting on the toes with heels above the ground, the belly should be vigorously moved from left to right and right to left as in vomiting. This is called Nauli.

Ch 2 v 34: Nauli removes dyspepsia, increases digestion capability, produces happiness and destroys all diseases and disorders of the dosha (humours).

School of Yoga explains – Nauli technique: (Should be learned under supervision)

• Perform uddiyana.
• Contract rectus muscles in the abdomen and project them forward in a thrusting movement. Use hands to push the hip back and generate a forward movement of the abdominal rectus with the back.
• Center of the abdomen will come out. To isolate the right or left rectus, bend knee of the isolating side a little more than the other knee. Pressing hand on this bent knee, push the abdominus to the opposite side.
• Similarly, practice on the opposite side by bending the knee, pushing with the hand and isolating the rectus on the opposite side. The rectus muscle on either side of the abdominus muscle can be completely isolate when the opposite side is completely compressed.
• Hold for 3-5 counts.
• Performing once is enough.
• The drishti (gaze) recommended is nabhigre (middle of the navel)

School of Yoga explains – variations:

There are 4 variations:

• madhyama-nauli (isolation of rectus abdominis) – this is the standard nauli;
• dakshina-nauli (isolation of right rectus) – this is the ability to move the right rectus muscle into the abdomen while keeping the left constant,
• vama-nauli (isolation of left rectus) – here this is the ability to move the left rectus muscle into the abdomen while keeping the right constant,
• nauli-kriya (rotation of rectus abdominis) – this is the ability to rapidly alternate between vama and dakshina nauli, i.e. alternate rapidly between the right rectus muscle and left rectus muscles.
