Overview
The standing stomach vacuum is an isometric abdominal exercise designed to activate the transverse abdominis—the deepest layer of abdominal muscles. Unlike crunches or planks, this movement focuses on drawing the belly inward to improve core stability, posture, and muscle control. It is often used in bodybuilding, Pilates, and rehab settings to strengthen the internal core musculature. (Read this page for more details on Stomach vacuum exercises.)
