I asked my OB this at the start of this pg. She said not over 130

Mind you I am pretty fit and was at the gym three times a week and getting HR up around 190 when really working out. So going to 130 has been a drag. I do think it is because there is not as much oxygen getting to bubs when our heart is racing.

The other things to look out for are not getting a sweat up, not getting breathless and obviously not working so hard that you get dizzy. It really is something that I would ask your care giver about though. I would think it would be different for some women than for others - I am considered a high risk pregnancy so maybe my OB was being more cautious than what you would need?

I miss that rush at the gym though!
