The abdominals, also known as the abdominal muscles, are a group of muscles located at the front of the abdomen. They include the rectus abdominis, the external and internal obliques, and the transverse abdominis. These muscles play an essential role in trunk stability, trunk flexion and rotation, and breathing. They are called upon during exercises such as crunches, planks and trunk rotations. In addition to their aesthetic role in contributing to a flat, sculpted stomach, strong abdominals can help improve posture, prevent low-back pain and enhance performance in sporting activities.
