Amazon.com Sylvia Klein Olkin is a long-time yoga instructor who developed the Positive Pregnancy Fitness (PPF) program， a prenatal health care program that is now taught in more than 30 states. Positive Pregnancy Fitness presents a gentle and sensible approach to exercise that incorporates yoga with nutrition and stress management. The exercises--described clearly and illustrated with crisp black-and-white drawings--are well adapted for pregnant bodies. The PPF program includes meditation， physical stretches， breathing， herbs， visualization， relaxation exercises， and massage and pressure points. Olkin's approach is to treat the entire woman， not just the pregnant parts of her. Positive Pregnancy Fitness can be used as a home accompaniment to PPF classes， for self-teaching， or as a resource book for teachers of childbirth and prenatal exercise. It provides healthful tools that pregnant women can use for fitness and overall health far past pregnancy. From Publishers Weekly Olkin held her first yoga-oriented Positive Pregnancy Fitness class in 1975， and since then over 10，000 women have benefited from her holistic guidance on prenatal health， birthing and the postnatal period. Although occasionally marred by New Age jargon， this illustrated handbook is full of so much sound physiologically based information that it deserves a wide audience. Throughout the text， she places an emphasis on maintaining a calm， assured mood， and toward that goal， she offers execises for strengthening the body， breathing methods， stress management procedures and nutritional advice that are supplemented by explanations of the birth process and a primer for nursing mothers.
