Exercise builds muscles needed during labor, reduces stress levels and increases energy levels. Before starting any exercise activity, consult your physician first. If you never or rarely exercised before conceiving, take it slow. Brisk walking is one of the best aerobic activities that offers a good workout without straining any joints or muscles. Swimming is another low impact activity that offers little strain on muscles.
Cycling is also good for expecting mothers.
Stationary bikes are even better, because there is less chance of falling. They should also not participate in contact sports or pick up any new activities. According to the American College of Obstetricians and Gynecologists, women that are accustomed to aerobic activity should be encouraged to continue during pregnancy. Whether you are starting an exercise routine or continuing on a program avoid a vigorous activity. Choose an exercise that you enjoy.
