Loop a long resistance band around a secure anchor point at lower chest height. Grip the other end of the resistance band firmly in both hands and stand with your right side parallel to anchor point. Ensure you are far enough away from the anchor point 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 your hands 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.
