Put a stability ball on the top half of a gym mat. Place your knees in front of you on the mat, making sure that your arms are straight when placed on the ball. Ensure that your whole spine is in a straight line. Gently turn the ball to the right, keeping your hips in place. You should feel a slight stretch along the left side of your torso.Bring the ball back to the center, then turn the ball to the left. Return to the starting position and repeat this exercise 10-15 times.
