We're delighted to hear that you're getting such excellent results! Several exercises in Strong Women Stay Slim address the abs, but you're right: most people do need more. You could add the abdominal crunches from our first book, Strong Women Stay Young (see page 179) or the supplemental exercises in Strong Women Stay Slim (doing the front-leg raise on page 145 with your arms across your chest gives your abdomen an even tougher workout). Also, select aerobic activities that work the abs. Good choices are rowing, stair climbing, walking and biking. Remember that all aerobic exercise contributes to a trimmer mid-section because it helps burn the fat layer on top of the abdominal muscles.
