Toned stomach muscles provide the core strength you need for healthy posture, reduced back pain, and more effective cardio workouts. For best results, perform your ab workouts 3-4 days a week on alternating days.

As with any fitness routine, variety is key. Strive for a mixture of traditional sit-ups to work the upper abdominals, leg raises and pelvic tilts to target the lower stomach muscles, and side twists and standing arm raises to work the obliques. By combining regular abdominal workouts with a sensible, low-fat diet, you should begin to see your hard work pay off in just a few weeks.
