An individual can do a thousand crunches each day, and it still will not provide a six-pack abdomen; to get a six-pack, individuals need to work all of the muscle groups in the abdomen. The upper abs, lower abs and obliques must be built so that they have a prominent appearance.
Crunches work the upper abs, but a six-pack is not created solely from the upper abs. Leg raises work the lower abs, while oblique crunches build the obliques. To build muscle, abdominal workouts should be done approximately four times a week and focus on high weight or tension with fewer repetitions. To get to a low body fat that showcases the abs, an individual should eat a healthy diet with less calories than he or she needs to maintain his or her weight.
