cable twist (up-down)

Stand with your feet shoulder-width apart, facing the cable machine. Hold the cable handle with both hands in front of your chest, keeping your arms slightly bent. Engage your core and slowly rotate your torso to one side, keeping your hips and legs stable. Pause for a moment at the end of the rotation, then slowly return to the starting position. Repeat the rotation to the opposite side. Continue alternating sides for the desired number of repetitions.
