Stomach Vacuum

What it is

This isolation exercise targets your deep core muscles, primarily the transversus abdominis. You perform it by deeply drawing your navel towards your spine, holding a sustained isometric contraction. It helps improve internal core stability and muscular control. This movement uses only your body weight.

Technique tips

• Fully exhale all air before drawing your stomach inward.
• Imagine pulling your belly button towards your backbone.
• Focus on maintaining light, normal breathing during the hold.
• Begin with 20-second holds and gradually increase duration.
• Maintain a tall, upright posture throughout the exercise.

How to track your progress

Log the hold time of each set. Straddly keeps your best hold for this exercise and tells you when you beat it, so a two-second gain does not go unnoticed.
