The kneeling rotational chop increases power and strength with an emphasis on the obliques.
Kneel on the floor with both knees with your working side closer to an adjustable cable machine. Make sure to keep your chest up and torso erect. Grab a rope attachment from the highest level on the machine with an overhand grip and extend arms so they are completely straight, making sure that your hands are shoulder-width apart.
Tighten your abs and squeeze your glutes, using your torso to pull the rope down and across your body, past your opposite hip. Return to the starting position.
