The dumbbell side bend works the obliques.
Standing with feet hip-width apart, a dumbbell in one hand, the other hand on your hip or behind your head.
Bend your torso toward the dumbbell side, then straighten up by contracting the opposite side. Switch sides.
Stay in the lateral plane: do not lean forward or backward.
