A common misconception is that by toning abdominal muscles belly fat will simply melt away and the stomach will flatten out. Unfortunately this is not a belly fat cure that works and fast ab workouts don't do much for calorie burning and fat loss. There are several reasons for this but by making simple adjustments in your workout and diet you will soon be on your way to seeing 6 pack abs.
Fast ab workouts that include 100 different styles of crunches are very ineffective for burning fat. The abdominal muscle is a small muscle group and when it is isolated it doesn't require a lot of effort to contract the abs. You can work on toning abdominal muscles while working your whole body and getting a better fat burning workout by adding the right exercises. A stability ball offers several variations of exercises that require not only more core muscles but also stabilizing muscles like your arms and chest.
