No matter how many ab workouts you do, they won't help you reduce belly fat. Instead of focusing on spot reduction — targeting one specific area on your body — you've got to train your entire body, fuel up with nutritious foods, and make sure that you're recovering (nope, all-nighters won't help) to lose fat in general. And losing body fat all over means you will be losing some on your belly as well.
Two weeks doesn’t give you much time to trigger noticeable changes in your body. To negate the time factor, you’ll be condensing the work schedule. Over the next 14 days, you’ll put in 12 total workouts, with two rest days built in. The increased frequency of workouts will up the number of calories you’re burning over the course of the program. By keeping repair and recovery constant between workouts, you’ll have your metabolism working overtime to keep up. This type of schedule is not sustainable in the long term, but you’ll find that your body can do almost anything for a two-week block, often with positive results.
"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it. HIIT training (high intensity interval training) is a great way to burn fat and get your heart rate up. Squats, burpees and treadmill sprints are all examples to try."
