The sad truth of all exercise programs is that you have to follow them to get results. This one is no different, but its well-designed, progressive strength-training promises the fountain of youth in two 40-minute sessions a week. An extravagant claim? Yes. But many women, especially those between age 40 and 80, can achieve certain measures of youth: denser bones, better balance and flexibility, more strength and energy than women years younger. The guidelines in Strong Women Stay Young are backed with solid--though small--studies and thorough explanations of how aging changes your body. Authors Miriam E. Nelson and Sarah Wernick include clear charts, instructions, and exercise illustrations featuring women who carry extra pounds and years gracefully.
