Swiss Ball Lying Oblique Twist

Instructions

With a swiss ball in front of you, lie down with your back on the floor. Place the ball between your feet and squeeze your legs together to keep it in place. Raise your feet off the floor until your thighs form a 90 degree angle with your torso.

From this position, and with your arms on the floor, twist your hips to one side, bringing your legs down towards the floor as low as you can, whilst keeping your shoulder blades on the floor. Reverse the movement and twist to the other side. Repeat for the programmed amount of repetitions.
