The Fitness Institute’s Pre/Postnatal Care expert Corry Matthews answers questions and shares insight on keeping fit while expecting.
What to keep in mind. The most important thing to keep in mind during the first 12 weeks of pregnancy is to keep your heart rate under 140 beats per minute, stay well hydrated and avoid exercising in the heat or on unstable terrain. In addition, women in their second and third trimesters should avoid exercising on their back for more than a minute because of the potential danger to the mom and womb. “The reason for this is that the baby’s weight can suppress the mother’s blood circulation, and this can make the mom very dizzy or even cause her to pass out from a lack of blood and oxygen,” says Matthews.
