Set-up: Find a cable tower with handles that can be positioned adjacent to one another at hip height. Keeping your back neutral and core braced, face the tower and grasp the two handles.
Movement: Without letting your shoulders or shoulder blades round forward, and with a slight bend in the elbows, pull the cables apart to your sides until both arms are parallel to the floor. Do not use momentum or swing your body. Return the cables to the start position under control.
