Your doctor can help you to find a routine that suits you best. Just because you are going to start exercising, it does not necessarily mean that you have to head for the gym and struggle with weights for two hours every day. There are many ways to get fit. Pick an activity that you can have fun with and that will keep you motivated. Walking for 20 minutes three to four times a week can have an enormous, positive impact on your health.
Swimming is a great form of exercise too.
It is not safe to continue any high-impact sports or exercises once you have successfully conceived. High-impact sports pose a high risk for injury, plus they can raise your body temperature to an unsuitable level for a healthy pregnancy. There are many things that you expose yourself to each day that can be harmful to a pregnancy. You need to be aware of what you are exposed to while you are trying to conceive and especially once you are pregnant. It is easy to control what you put into your own body, but it isn't always as easy to control the environment around you and the effects it has on your body.
