No Sweat, No Good in Pregnancy

Vigorous exercise crucial while pregnant

(RxWiki News) Old wives tales regarding pregnancy are plentiful, such as carrying the baby high means it's a girl and exercise during pregnancy will hurt the fetus. The one about exercise hurting the baby can be laid to rest.

Vigorous exercise offers the best chance to remain healthy during pregnancy and provides a healthy environment for the baby. A cardio workout and light weight lifting decreases the risk for disease and can prevent excess weight gain.

"Exercise during pregnancy can improve your health."

Research shows that intense exercise, meaning getting the heart rate up to 60 percent of its maximum capacity, can reduce the risk of gestational diabetes during pregnancy. Gradually increasing one's physical activity is shown to be safe for both the mom and baby, according to revised workout guidelines for expecting moms.

Also, a regular exercise program helps eliminate excess weight gain during pregnancy and all the obesity-related problems that excessive weight gain can cause.
