Start off lying on the floor, face up, with your legs bent and feet flat on the floor. Reach your arms down by your sides, held just off the floor. Engage your core by drawing your belly button and waist down towards your spine. Also, tuck your chin in slightly as if you are holding a tennis ball between your chin and chest. Then slowly, tense your upper abdominals to lift your head, then neck, then shoulders and upper back off the floor. Keep you lower back on the floor and do not let it arch away from the floor. This is your start position. Twist your torso to the side and reach down with your right hand to touch your right ankle. Immediatley reach down with your left hand to touch your left ankle. Repeat. Continue this small focused movement and contraction of your core muscles for the duration of the exercise.
