Crunches are a simple, but effective exercise that can reduce a sagging stomach. There are a variety of ways that a crunch can be done. Howtobefit.com discusses three basic types of crunches that strengthen stomach muscle, thus reducing the sag. These are the basic crunch, the reverse crunch and the side crunch.
Do a basic crunch by laying on the floor with your knees bent. Place your hands behind your head. Lift your shoulders and upper back off the floor while contracting your stomach muscles. Hold that position for two seconds. Do not sit all the way up. Slowly lower yourself back down. The reverse crunch is the opposite of the basic crunch. Get into the same starting position. Instead of lifting your upper body, though, you will be curling your knees up. Hold the position for two seconds then slowly lower your legs back down. Repeat these exercises 12 to 15 times.
The side crunch will work the muscles on the sides of your stomach. Howtobefit.com says, "Begin by lying down on the floor with your knees bent and your torso twisted so your left leg is lying flat on the floor but your upper body is still facing upward." Place your hands behind your head. Slowly lift your shoulders off the floor in a twisting motion. You should now be lying on your side with your face and legs facing the same way. Slowly lower yourself back to the starting position. Repeat 12 to 15 times and then turn to the other side.
EDiets says that "studies actually prove this to be one of the most effective" exercise when it comes to strengthening a sagging stomach. Start by lying on the floor. Place your hands behind your head. Lift your legs and bend your knees at a 45 degree angle. Slowly begin moving your legs as if you were peddling a bicycle. As you pedal, twist your body so that your elbows meet your knees as they come back toward your head. They should not touch. Do not pull up on your neck during this exercise. "The lower to the ground your legs bicycle, the harder your abs have to work," says EDiets. Do this exercise for about 2 minutes.
Reducing a sagging stomach is not all about strengthening your stomach muscles. You also have to burn fat. You can do these two things at the same time by doing 20 minutes of cardio exercise with each workout. "Walking puts all of the abdominal muscles to work. Make sure you swing your arms and contract your midsection while you walk, and maintain a brisk pace," says ShapeupShop.com. You might also try cardio exercises like jogging, swimming and cycling.
