I think this belt is a forced version of an ab excersize:
Stomach Vacuum
Exercise Data
Main Muscle Worked: Abdominals
Other Muscles Worked: None
Equipment: BodyOnly
Mechanics Type: Isolation
Tips: Works the transversus abdominus and internal obliques. This gives you a flatter profile and a narrower waist!
To execute the Stomach Vacuum, stand upright and place your hands on your hips, and exhale all the air out of your lungs, completely. Expand your chest, and bring your stomach in as much as possible, and hold. Visualize trying to touch your navel to your backbone. One isometric contraction of "20" seconds is one repetition. You can work your way up to 40 or 60 seconds.
Once mastered, the Stomach Vacuum can be performed in a standing, kneeling, seated, and lying position.
