Lie face-down on an exercise mat, hand on your lower back, palms facing up. Keep your legs on the mat throughout the exercise. Squeeze your buttocks then lift your upper body 2-3 cm (approx. 1 inch) off the mat. Hold for 3-5 seconds then lower yourself back down gently. Repeat 10 - 12 times, rest, then repeat the exercise sequence as desired.
