Safe exercises include walking or jogging, aerobics, yoga, swimming, or dancing. Swimming is probably one of the best all around exercises for pregnant women. Women who are active tend to limit some of the unnecessary weight gain and have an easier time getting back to their pre-pregnancy form. Exercise also improves mood and sleep, strengthens important muscles for labor and helps limit some of the normal aches and pains. http://www.rupalhospital.com/gynaecology.html
