Do I need to monitor my heart rate when exercising when trying to get pregnant?

 

It's an outdated myth that pregnant women shouldn't raise their heart rates above 140 beats per minute. Experts recommend you do the "talk test" to determine the intensity of a workout. You should be able to talk without gasping for air, but your heart should be pumping. If you can't catch your breath or can't speak easily, slow down.
