Exercise ball hug

Sit on the stability ball with your feet flat on the ground and your back straight. Hold the stability ball with both hands, hugging it close to your chest. Engage your core muscles and slowly lean back, keeping your back straight and your feet planted on the ground. Continue leaning back until you feel a stretch in your back muscles. Hold the position for a few seconds, then slowly return to the starting position. Repeat for the desired number of repetitions.
