Is crunch good for abs?

Like situps, crunches help you build muscle. But unlike situps, they work only the abdominal muscles . This intense muscle isolation makes them a popular exercise for people trying to get six-pack abs. This also makes them ideal for strengthening your core, which includes your lower back muscles and obliques.
