All the research says that we humans can't spot reduce our weight so please bear this in mind if you're trying to shape up any particular body part. This aside, the best way you can prepare your body for a six pack is to find exercises/activities that target that area, in your case for example, crunches and/or paddling, and combine these with 2-3 cardio sessions per week to reduce overall body fat. Weight bearing activities that make you huff and puff are best. Of course, you can do all of the above but if your workouts aren't enough to burn off the amount of food you're eating each day, you'll still never see your abs. This is called the energy balance. Get interested in what you're putting in your mouth and the kilojoule value of your food. The problems usually start here. As for how long it takes, it depends on so many things - your starting weight, whether you choose to combine your exercise with a healthy eating plan, your metabolism, where your body chooses to drop weight from first, your starting level of fitness - to name just a few. Congratulations on taking this first step. It's well documented that excess stomach fat is not good for long term health.
