Femalefirst.co.uk lists four exercises, along with some cardio and healthy eating tips that can help in getting abs in no time.
* Torso Rotations: Torso rotations are great for working your whole abdominal area, including your lower back. These are done with your body alone or with a broomstick! Stand with your feet shoulder-width apart, hands on your hips whilst keeping your lower body still, rotate your upper body as far to the left and right as possible. This should be done in steady movements for 15 to 20 repetitions at a time.
If using the broomstick, lay it across your shoulders and hold it with a wide grip.
* Lying Twist: The lying twist also works the oblique muscles and improves flexibility. Lie on the floor with your legs straight out in front of you and your arms are out to the side, with your palms flat on the floor. Lift your legs so that they are at a 90 degree angle to the ceiling, then slowly lower them down to the right as far as possible and then slowly repeat on the left side. Continue to repeat this movement in a slow and controlled movement.
* Leg Lifts: Leg lifts are achieved by lying on the floor with your legs straight. Raise them five inches from the floor either together or on their own depending on your ability and hold them for about 30 seconds. Your back should be close to the floor. Be careful if you have previous back problems when doing this move.
* The Plank: This classic exercise is usually performed at the end of a workout. But it can also be done at any time and in front of the TV is ideal! You need to be in a similar position as a press up but rest on your forearms instead. Ensure you have a straight back and neck and hold this position for as long as you can, this is beneficial for your core muscles, especially your inner and outer abs.
