Attach a bar to a high cable pulley. Sit with feet flat, thighs secured. Grip the bar underhand, shoulder-width apart. Lean back slightly, chest up, core engaged. Pull the bar down towards your upper chest, driving elbows down and back. Squeeze shoulder blades at the bottom. Slowly extend arms to the starting position, controlling the weight.
Keep elbows close to your body. Avoid momentum; focus on controlled movements. Maintain a slight lower back arch. Exhale on the pull, inhale on the return. Grip firmly, but avoid excessive tightness.
