Slowly raise your shoulders and upper back by contracting your abs (about 30 degrees), twisting to the left, touching your right elbow to your left knee. Exhale during this movement. Hold this position for 2-3 seconds. Slowly return to the starting position. Inhale during this movement.

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.
