String
So, what should you do with that piece of string we mentioned? It’s very simple. You have to tie the string around your waist and tighten your stomach muscles slightly (about 50 per cent). That way, you’ll feel the string around your belly, but it won’t be too tight. Why does this help and what does it do? Apparently, having a piece of string tied around your waste causes you to keep remembering to tighten your muscles, which in turn is said to result in a flatter stomach. Without going to the gym! Can it really be that simple? There’s no harm in trying, so if you want a flat stomach you could always try this out!
