Exercise during pregnancy is usually considered safe for most healthy women, and may also contribute to solving some of the discomfort of pregnancy. Some types of exercises that are especially good for pregnant women are walking, swimming, cycling and stationary yoga. American College of Obstetricians and Gynecologists recommends that you focus on non-weight-bearing activity and those that do not require a huge amount of balance (because some of them very complex Yoga poses can be before the birth). Wear loose fitting, light clothing in the exercise, get plenty of fluids and not working at the point of exhaustion. When you reach the second and third trimesters, do not do exercises that require lying on your back, and never do an exercise that presents a risk of injury in the abdomen during pregnancy. And always check with your doctor about exercise program before starting work. Some women - such as those with preeclampsia, premature birth, and high blood pressure and heart disease - may be asked not to exercise or go on a very limited physical activity during pregnancy.
