The internal obliques can function bilaterally, which means both sides work together. Bilaterally they flex the trunk and compress its contents. They can also function unilaterally, which means one-sided. Unilaterally, they laterally flex the trunk and rotate it to the same side. Like the internal obliques, the external obliques function.
