Women in a low risk pregnancy are highly encouraged to stay active. Pregnancy is not the time however to start up a new or more rigorous activity. If you were pretty active prior to getting pregnant you are better prepared to continue that activity (with your doctor/midwife’s approval). Walking is always a great choice as it is low impact and can be started at any time (and is encouraged throughout pregnancy)!
When exercising it is important to remember your body is changing and the hormones of pregnancy can cause you to be less balanced. (Watch those activities that require a lot of coordination!)
It may be helpful to borrow or invest in a heart rate monitor so that you can be sure you aren’t exceeding your target heart rate for extended periods of time and know when to back down.
