Article: Sucking your stomach muscles to your spine immediately flattens your belly. Additionally, the action of pulling your stomach in will support your spine and help prevent any back problems that can arise from carrying extra weight. This action will create the look of a wider top and smaller waistline. Maintaining a straight or slight s-curve in your spine will help you appear slimmer and prevent your stomach from sticking out.  Avoid over-arching your back. Don't slouch, which will will prevent you from tucking your stomach in and will make your belly look bigger than it actually is. Wearing heels naturally improves your posture by rotating your hips to tuck your bottom in and helping keep your back and shoulder straight. Even a classic dress shoe with a small heel can be enough to reap these benefits.

What is a summary?
Pull in your tummy. Square your shoulders and lift your chest. Keep your back straight. Wear a heeled shoe to automatically stand up straighter.
