Being pregnant is a workout, but being in shape through it can help. When it comes time for delivery a body that is in good shape is more able to deal with the rigors of childbirth. According to the National Institutes of Health, joints loosen during pregnancy, and therefore it is important not to do exercises that require fast movements. Of course, activities that can cause injury should be avoided also. For a list of activities to avoid and other information about what to do and what not to do during pregnancy go to the NIH Web site.
