There is much more to getting a flat belly than doing 100 crunches a day. One area of your abs you might be neglecting is the Transversus Abdominis muscle, also known as the “corset muscle”. This is the muscle that tightens when you cough, sneeze, or laugh.
In addition to regular cardio and eating clean, working these deep abdominal muscles will help pull in your waistline like a natural corset and flatten your stomach. You will also
notice that your posture will improve and your lower back strengthened.
