Moms-to-be have long been discouraged from exercise to avoid harm to the fetus. It used to be thought that exercise during pregnancy contributed to low birth weight, premature birth, and even miscarriage. Researchers, however, are now finding that moderate physical activity may actually reduce the risk of birth complications.
Studies show that expectant moms who get at least 150 minutes of moderate-intensity aerobic activity per week may prevent gestational diabetes, relieve stress, and build enough stamina needed for labor and delivery. For more information on exercise routines during and after pregnancy, a complete copy of the 2008 Physical Activity Guidelines from the U.S. Department of Health and Human Services is available for moms to download here.
