flatter tummy

For a flatter tummy, you'll need to make sure your diet is on point. That saying "Abs are made in the kitchen" is true if a little annoying! Crunches, planks - anything core related are good in general but make sure you are getting a good overall body work-out, so some good bouts of cardio and some strength training too. I'd say, continue with the calorie counting and you'll see results!

No exercise will give you a flatter stomach as you cannot spot reduce fat. What you will want to do is eat at a deficit, get enough protein, and take part in a progressive strength training program... The reason, the caloric deficit will cause you to lose weight, the strength training and protein will help retain the muscle you already have which means most of your loss will come from fat, eventually, depending on genetics for how fast, you will lose the fat in your stomach area.
