A fitness fanatic demonstrated an ancient yogic cleansing technique with precise abdominal control.

Footage shows the yogini performing the Nauli Kriya, a yoga exercise known for its deep internal cleansing effects, in Zhejiang, China.

She can be seen controlling the contraction of her abdomen, churning and rotating her rectus abdominis muscles on October 11.

Her stomach moves in rhythm with her breathing, the muscles pulsing in steady waves that strengthen her core control.

Health enthusiasts said that the practice is one of the most effective methods for balancing body and mind through natural movement and breath control. It is also believed to stimulate the internal organs and improve digestion.
