There is no short answer to this question though.
If you are already fit, and you exercise regularly, then the experts agree that as long as you and the baby are healthy, it’s safe to continue during the first trimester of your pregnancy. After that, your doctor should be able to advise you on what exercises are safe, and what you should avoid.
It’s also worth remembering that your body is undergoing some pretty intense changes. For instance, your heart rate has increased, thanks to an additional 50 percent blood that it’s got to pump around your body! You may also have morning sickness, and there’s a good chance you’re feeling more tired than usual. It’s more important than ever to take it easy, and remember to stretch. Taking up a lower impact form of exercise, like walking or yoga, is another great way to keep in shape, but stay safe.
Being fit can help you to have an easier labour, but always remember that your safety and that of your baby come first.
