What? Jesus Christ, NO! The one and ONLY thing that will get you visible abs is nutrition. Situps and weighted ab exercises will give you stronger and bigger abs, but if there's fat on top of them, NOBODY CAN SEE THEM. Doing situps doesn't reduce the fat on your belly. You CANNOT SPOT REDUCE. This thing pisses me off in a thousand ways. If you have fat on your belly, you need to go through a cutting phase. This means you need to be in a caloric deficit so that you burn the fat. Read the fat loss thread sticky. That applies for cutting too and is exactly how you would "get abs."
