4. From a prone face up position with heels on Swiss Ball and shoulders on floor bring heels up to buttocks and back while refraining from allowing the hips to sag throughout movement.

The degree of difficulty can be adjusted by placing the Ball closer to the hips (easier) or closer to the feet (difficult). In  exercise #4 by spreading arms away from body stability is improved (easier) and by keeping arms crossed on chest stability is decreased (difficult).
