But attitudes have changed and women such as Byrne are enjoying the benefits of exercise. You can't totally prepare for the rigors of childbirth, but exercising during pregnancy can give you an added edge. If you already are physically fit, exercising during your pregnancy makes good sense. Regular activity can help prevent varicose veins, constipation, hemorrhoids, fatigue and lower back pain. It also can provide that mental boost a lot of women need as their bodies and hormones go through the various changes of pregnancy.
Exercise can bolster confidence and a sense of well-being, while decreasing tension and anxiety.
There is no proof that exercise shortens labor or makes it easier, or that it improves the baby's health. But many women report that working out helped prepare them for the strenuous challenges of childbirth. Still others report shortened recovery times. It also can be helpful in preparing for the physical demands of lifting and carrying a growing child. Four women who exercised before and during pregnancy discussed their experiences with me.
