Say it like a mantra: your stomach is more than your abs. While the six-pack may be the star of the show, it's your other core muscles -- the obliques and transverse abdominis. For faster toning, hit your core from all sides through workouts and healthy eating. You'll start with two reliable standards. You'll then challenge your body with variations that target your entire core. Perform cardio and integrate a bloat-busting diet, and you'll see noticeable tummy subtraction in four weeks.
