The stomach vacuum is an isometric contraction of the TVA (your deepest abdominal muscle). The stomach vacuum involves breathing out air and maintaining the breathless hold whilst "sucking in" the stomach to engage the TVA. It generates negative pressure in the abdomen. It will help you get really connected to your diaphragm, TVA and pelvic floor. It’s worth learning because it will help you practice engaging your TVA and deep spinal stabilizing muscles. As a bonus, with daily practice, it will further shrink your waistline and increase your core strength and stability. Plus, it’s a prerequisite for learning Nauli Kriya.
