Set up a cable station pulley at lower chest height with a handle attachment. Stand with your left side next to a cable machine and grip the handle firmly in both hands. Ensure you are far enough away from the cable to keep tension on it throughout the movement. Stand tall with your feet shoulder width apart, keeping your core braced and a flat back. This is your start position. Without rotating your torso slowly push the handle out in front of you, away from your body, exhaling as you do so. Feel the tension in your abs and obliques. Pause for a count of one and return to the start position, inhaling as you do so. Repeat all the required reps (or time) on one side before changing to the other.
