Start by standing sideways to the cable machine with the cable in a position close to the ground. Hold the handle in the hand closest to the cable machine. The diagonal pulling direction is up from below. Bend your trunk against the resistance of the cable to the opposite side while keeping your arm straight. Keep your other arm propped on your hip to stabilize the movement. In a controlled manner return to the starting position.
Tighten your stomach to keep your pelvis stabilized during this exercise.
