Keep a flat stomach to gain a flatter tummy.

Lie with your back on the floor your feet hip-width apart. Lay your hands over your stomach with your thumbs level with the bottom of you diaphragm.

Now take a deep breath and as you exhale, use your abs to lift your shoulders and ribcage. With your hands on your stomach it should remain flat at all times. As soon as you feel your stomach starting to lift stop and return back to your starting position

Do as many repetitions as you can.

Nicki's Tip: By pulling your tummy muscles in and up you'll notice the curl starts to happen naturally without much effort from the rest of your body.
