1 - Basic Jackknife

This Ab Lounge exercise is also called an abdominal curl. It isolates the muscle that runs down the entire front of your torso, known as the rectus abdominis. Relax back into your unit with your knees bent and feet placed on the foot rest. Place your hands overhand on the pull up strap, about shoulder width apart. Exhale and slowly round your lower back, pulling your torso forward into a curl position.
