1. Get Your Posture Right –
A good posture is the first step to a flat belly. Often, slumping and slouching accentuate your stomach, and over time, as you sit with a slouch continually, you will notice a little paunch. Standing up straight will immediately reduce a few pounds, making those abs look flatter almost in an instant.
To stand straight, imagine a rope pulling your upper body towards the ceiling, and you will already feel your shoulders rise. To improve your posture while sitting, make sure your feet touch the floor at all times. You could also place a pillow at the small of your back to make sure you are pulled forward on your chair.
