" There are no data in humans to indicate that pregnant women should limit exercise intensity and lower target heart rates because of potential adverse effects. For women who do not have any additional risk factors for adverse maternal or perinatal outcome."
This is from a study done by The American College of Obstetricians and Gynecologists. They do, however, recommend that pregnant women not do any excercises in the supine position and no ab work after the 1st trimester. Avoid doing workouts on hot days or getting overheated because it can cause birth defects and of course stay hydrated.

My family doctor had told me that I should limit my HR to 140 beats during pregnancy. My husband and I teach spinning and to maintain a lower heartrate is almost impossible but I do not want to give it up.
If you're looking for any type of an answer... that is the advice that had been given to me.
On a second note, if you exercise during pregnancy... your baby will be more likely to quite themself.

I wasn't looking for an answer really, every professional I have spoken to told me the HR thing isn't really important. An older, sedentary, overweight woman will have a different resting heart rate than a very active, slim, 20 year old so the 140BPM is not really based on anything.
My doctor told me that as long as I FEEL fine while working out (not dizzy, etc) that I am fine to exceed that 140 HR ( my resting heart rate is higher anyway.)
