Regular exercise is important during pregnancy to maintain a healthy lifestyle. Walking, swimming, bicycle riding, and prenantal exercise classes are all recommended. You may continue normal sports activity, although it is not the time to take up a new sport. The American College of Obstetricians and Gynecologists recommends keeping the heart rate under 140 (take your pulse for 6 seconds, multiply by 10). Do not exercise lying flat on your back after five months of pregnancy. Some activities are not recommended during pregnancy: snow skiing, water skiing, and horseback riding.
