Abdominal exercises. In order to get defined abdominal muscles, you have to work on developing the muscles and reducing the amount of fat covering the muscles. Simply exercising the ab muscles alone won’t achieve the best results. You must combine healthy eating, cardio and strength training which is intense enough to fatigue your abs and need recovery, like sit-ups and crunches. Do a few sets of 10-30 reps daily.
Core strength. Core strengthening exercises will help to keep your abdominal muscles in shape. Here's a useful slideshow: http://www. Mayoclinic.
