Abdominal Crunch

Lie on your back with your knees bent and your feet flat on the floor. With your arms straight and hands reaching for your knees, activate your abdominal muscles until your shoulders lift off the floor (figure 4.18). Return to a resting position briefly, and repeat 8 to 12 times per set. Complete 3 sets.
