We all want that nice flat stomach, but with that comes some serious work, until now?

Apparently all you need is a string to remind yourself to stand up straight and suck your gut in. Yeah I am sure this works awesome If you are are already skinny, but If you are a normal size person that ties a string around your waist when you are sucking in, that is going to be awfully uncomfortable. Plus who can suck it in all day long?

Crunches are sounding a lot more appealing and realistic right now.
