I really agree with this. I'm in my first pregnancy and a fitness/wellness professional. I used a heart rate monitor at first to keep my rate at 140 bpm, as recommended. I found that I could easily go higher, and I just *knew* everything was fine. Because your heart beats faster in pregnancy by about 10-15 bpm, I noticed my heart rate increased quicker during slow jogging or spinning than it did when I wasn't pregnant. So I quickly figured out that worrying about heart rate and core temp is kind of crap, imo. If you're already used to exercising.
The thing that slowed me down is that I could feel as my pelvis changed, I really didn't *want* to pound the pavement (or the treadmill). Spinning has been a great low-impact cardio, as is walking up hills (or steep incline on the treadmill). I'll still jog here and there (28 weeks pregnant now), but it's slow and not for long. I will mention that I love jogging, but was not a hard-core runner. Just a few miles, a few days a week.
I have managed to be pain-free all pregnancy, which is my ultimate goal. I know a lot of women who pushed too hard, injured themselves, and then were benched from any activity. So I'm trying to tread that line. I also agree that there are lots of women who are afraid to move at all, so finding that balance is really key. My advice is, continue doing what you're doing, but be *willing* to stop if your intuition says so. Be willing to spend longer exercising, also. I used to do 30 minutes of high intensity interval training (sprints and then strength back and forth). I can't work out with that intensity anymore, so I do at least 45-60 minutes of cardio/strength now.
