Lie on your back, knees bent and feet flat. Keeping your buttocks and legs relaxed, inhale, then exhale and draw your deep abdominal muscles in toward your spine, tilting your pelvis up and gently touching your lower back to the floor [A]. Place your hands on your belly, and use your fingertips to gently draw the lower ab muscles in even more while contracting them [B]. Hold for a count of 3, breathing normally, then release. Repeat 4 more times.
