1 Alter your diet to include more vegetables and lean proteins and less fat and sugar. Lean proteins will help you build muscles and burn fat in your lower belly. Even if you simply cut your fat and sugar intake in half, it will make a big difference in your fight against lower belly fat.
2 Do at least a half hour of cardio three times a week. Walking, jogging, biking and dancing are great options. Doing cardio will help you lose that extra layer of fat that keeps your abdominal muscles hidden.
3 Work your lower ab muscles to strengthen the muscle wall and burn belly fat. Do a few reps of scissors after your cardio exercise. Lie on your back with your hands underneath your buttocks. Lift your legs about a foot off the ground. Contract your lower ab muscles, and move your legs in a crisscross motion: move your right leg over the left, then open your legs apart and move your left leg over the right. Be careful not to bend your knees. Do about 10 to 15 reps.
4 Do a few reps of double leg reverse crunches. Lie on your back with your hands behind your buttocks as in Step 3. Raise your legs off the ground and bend your knees. With your knees bent, slowly lower your feet until they're three inches off the ground, and hold this position for a few seconds then return to starting position. Do about 10 to 15 reps.
5 Complete your lower belly workout with a set of the Pilates 100. Lie on your back with your arms at your sides. Lift your legs straight at a 45-degree angle. Keeping your arms straight, lift them a few inches off the floor. Contract your abs and lift your shoulders a few inches off the ground. Maintain this position and start pumping your hands up and down as you count to 100.
