The abs can be divided into the abdominals themselves and the obliques. The obliques are the outer abs and are used in twisting movements. For the sake of exercising, the abdominals are sometimes divided into upper abs and lower abs (this is not a technical division but something for exercising). Both upper and lower abs are used in straight line ab exercises while the upper abs are also involved in twisting movements.
