That's mainly because targetting belly fat is a myth.
Burning fat is an all-body process, and you can't target where you lose weight from. Energy is delivered to the muscles via the bloodstream, NOT from being absorbed from surrounding fat stores. Abdominal exercises will strengthen the abdominal muscles, but they will do absolutely nothing about belly fat.
What you can do is to continue to reduce your overall body fat through a combination of cardio, all-body strength training and watching your intake, and some of it will naturally come off the belly. And there is a heap of articles on these three issues.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
