Pregnancy is an added stress to your body, and regular exercise can prepare you to better handle the new load. If you did resistance training before you became pregnant, resistance training to tone your arms during your pregnancy is safe to do as long as you and your baby are otherwise healthy. Once you pass the first trimester, your baby has grown to a point where it is not safe for you to exercise flat or nearly flat on your back. Incorporating standing arm exercises will enable you to tone your arms even with an expanding belly.
