The standing abdominal vacuum is an isometric core exercise where you exhale fully and draw your navel as far inward as possible, holding the contraction. It targets the transverse abdominis — the deepest abdominal muscle that acts like a natural corset around the waist. Consistent practice can tighten the waistline and improve core bracing for heavy lifts.

How to perform
- Stand tall with feet hip-width apart. Place your hands on your hips or at your sides.
- Exhale completely — empty your lungs fully.
- Without inhaling, draw your navel as far inward toward your spine as possible.
- Imagine trying to pull your belly button toward your backbone. The effort should feel like sucking in your stomach as hard as you can.
- Hold the vacuum for 10 to 30 seconds while breathing shallowly through your chest (not your belly).
- Release and take a few normal breaths before the next rep.
- Perform 3 to 5 holds per session. Build hold time progressively.
- This can also be performed on hands and knees (quadruped) or lying supine for easier versions.
