You may have heard from friends or other pregnant women that you should

keep your heart at a certain rate during pregnancy. Pregnancy and the extra

weight your body is carrying make your body work harder even when you

aren’t exercising.  Exercise increases the flow of oxygen and blood to the muscles being worked

and away from other important parts of the body. So it is important not to

overdo it during pregnancy.  The “talk test:”  If you are able to talk normally while

you are exercising, your heart rate is at an acceptable level.
