Stomach Vacuums Explained

It's thousands of years old and is the one exercise Arnold Schwarzenegger credits for creating his flat stomach.

So why is the stomach vacuum barely used today? And could it truly be history's most under-utilized exercise?

Recent studies have found the stomach vacuum:

- fights protrusion of the stomach by tightening the transverse abdominis, the body's corset muscle

- helps with lifts and injury prevention

- offers postural support and added stability

- relieves lower back pain

- treats diastasis recti abdominis, a condition that afflicts up to 60% of women after pregnancy
