Generally, if you regularly engaged in sports or other physical activities before pregnancy, you can continue them during pregnancy with the consent of your doctor. Exercise improves blood circulation, keeps muscles toned, improves appetite, helps with digestion and aids sleeping. It's easy to see why regular exercise is particularly important during pregnancy. Walking, swimming, water aerobics and stretching can help keep you fit.

Look for exercise videos for pregnant women at your library and local video rental stores. Remember to consult your doctor before starting any exercise program. Be sure to start slowly, and as your baby grows, you will tire more easily and require frequent rests. Also, be sure to drink plenty of water and stretch thoroughly before and after exercising.
