Is It Save to Exercise During Pregnancy?
Sure, it is, don’t worry. 
For most pregnant women, exercise throughout their nine months of pregnancy is completely safe. Besides the safety issue, studies have also shown that the mother and the baby will be healthier with regular exercise during pregnancy, and also contribute to a shorter labor and easier delivery. If you have not been a regular exerciser before you’re pregnant you still can do your pregnancy exercise safely with a few basic guidelines.
Pregnancy Exercise During First Trimester
Actually almost any activities that you were doing before pregnancy is safe to continue, of course with the exception of activities like skiing and contact sports. However it is suggested to ask your doctor’s suggestion about it since every woman has their own unique physical condition. Some women may have an early pregnancy complication such as bleeding, and in this case your doctor may suggest you to wait before you start your pregnancy exercise program until the risk of miscarriage has passed.
It will be better for you to pay attention to your body and follow its lead/sign to make your pregnancy exercise during your first trimester works. If, for example, you suffer morning sickness or extreme fatigue, you better cut off your exercice routine until you feel better. This is also not recommended to try to break your own record on how fast you can run a mile or how much weight you can bench press, for instance. It will be better for you take it slow and easy so your body will let you know how much of a workout it can handle.
Pregnancy Exercise During Second and Third Trimester
Your ever-expanding stomach may dictate much of your pregnancy exercise as you get closer to your due date. One addition to your workout that you can almost always continue without fail is your Kegel. These exercises can help with your labor and delivery as well as with urinary incontinence both during and after your pregnancy.
Keep track of your heart rate during your workouts to make sure it does not go above 140 beats per minute. Raising your heart rate also raises your baby’s, so anything higher can prove to be unsafe for both of you. Do not allow yourself to get overheated during exercise, and make sure that you are drinking plenty of water to avoid dehydration.
As you get closer to your delivery time, it is a good idea to avoid exercises that require bouncing or jumping, since your pelvic floor is already holding plenty of extra weight. If you develop high blood pressure or other complications in the latter part of your pregnancy, your doctor may want you to quit your workouts in favor of rest and relaxation. Your doctor is always your best source of determining how much pregnancy exercise is safe for you.

In 2002, ACOG, the American College of Obstetricians and Gynecologists, dropped their recommendation that pregnant women limit their HRs during exercise to less than 140BPM.
There is no scientific evidence to support your statement implying that exercising above 140BPM can harm either the baby or the mother.
Pregnant women should stay in their aerobic training zones, irregardless of HR. Some very fit women can exercise with ease above 140BPM, while less fit women will need to exercise at a much lower level.
Perceived exertion is the best way to monitor HR during pregnancy. Pregnant women should stay in a zone that is perceived as “somewhat difficult” and never get to the point of breathlessness or panting.
