This abs workout, designed by Angela Corcoran, a personal trainer at Equinox in New York City and professor of exercise physiology at Queens College in Flushing, New York, will help you build a stronger core by targeting different abdominal muscles, boosting your metabolism, and burning belly fat.
Hold a light, 3- to 5-pound weight in each hand (or use two cans of soup).
Keeping your arms straight, extend them out to your sides so your body forms the letter "T." This is your starting position.
Keep your knees straight as you hinge slightly at the hips and reach your right arm toward the ground. Return to starting upright position. Reach your left arm toward the ground and return to starting upright position to complete one rep. Be sure to keep your hips straight and centered as you perform this "teeter-totter" motion to each side.
Work up to 20 reps.
