If you say you burn around 2,800 calories with no workout= your maintenance calories. In order to get your "6-pack" you must consume less calories than you burn.
My suggestion would be to first, make sure your diet is nice and clean- lean proteins, healthy fats, and complex proteins. Then, track your daily intake on fitday.com and post the website on here so we can all take a look at your macros (total calories, proteins, fats carbs)- it does all the math for you- all you need to do is measure your food and input it on the fitday account.
Do that, then come back post and ask away.
