To perform it, set a cable pulley to shoulder height and get into a high plank position perpendicular to the machine, with one hand gripping the cable handle and the other on the floor. Keep your body in a straight line from head to heels, engage your core, and perform a controlled fly movement by bringing the cable handle across your chest while resisting rotation. Slowly return to the starting position and repeat. This movement strengthens the chest, shoulders, and core while enhancing balance, anti-rotational strength, and overall body control.
