The Russian twist targets the obliques through torso rotations.
Sit on the floor with bent knees, lean your torso backward with a straight back, and clasp your hands in front of your chest. Lift your feet off the floor for more difficulty.
Rotate your torso to one side to bring your hands near the floor, then to the other side.
The movement comes from the torso, not just the arms. Keep your back straight.
