Cable seated twist

Sit on a cable machine with your feet flat on the ground and your knees slightly bent. Hold the cable handle with both hands and extend your arms straight in front of you. Keeping your core engaged, slowly rotate your torso to one side, pulling the cable across your body. Pause for a moment at the end of the range of motion, then slowly rotate back to the starting position. Repeat on the other side. Continue alternating sides for the desired number of repetitions.
