Increase the amount of aerobic exercise you perform each day. Aerobic exercise burns calories and fat, which is needed to show abdominal muscles.
Reduce the total amount of carbohydrates you consume. Reduce simple carbohydrates with complex carbohydrates such as grains. Grains provide the energy you need to perform extra aerobic exercise and are metabolized by the body slower.
Interval training alternates high-energy exercises with low-energy exercises. This burns calories and fat around the abdominal muscles so they can be seen.
Target your core and keep your abdominal muscles tight and toned by exercising your ab muscles regularly. Exercises such as sit ups, abdominal crunches and hanging leg raises are effective in targeting the abdominal muscles.
Rest your abdominal muscles one day a week so they can recover and continue to effectively build strength. Allow yourself a break from your diet one day per week. Eating higher calorie foods once a week allows your mind to rest and mentally prepares you for another 6 days of intense training and clean eating.
