Many people do jogging. That works but it takes time.

1. Break your meals. instead of 3 considerable sized meals go for for 6, 8 or preferably 10 meals the size of your fist.

2. Sprinting. Faster effects. Do 10 crunches, get up and sprint for about 50 yards. Max speed for just 50 yards. Take a 60-90 second break. Repeat process. 5 times at first is good. Don't push yourself too hard. bring it up to about 12-15 times within 2 or 3 months. You don't want to hurt yourself.

This is info is from Brandon Carter. His videos are on the net. This statement is simply to give the credit to the right person.

Stomach fat is hard to get rid of. Instead of the above mentioned crunches you could try bicycle kicks. Standing bicycle kicks work too. Change and regulate your diet. Don't eliminate. When you reduce your intake your body adapts to store fat.

Again all credit to the mentioned above.
