Want a flat stomach?

Start with your diet. You could have amazing abs, but no one will see them if they’re covered in a layer of fat.

Planks. Whether you do them on a ball, on your forearms, or on your hands, they work wonders. 

Every single one of these will help you get a strong, defined, flat core.
