sportychick - maybe you should talk to the instructors at your gym about this... however I think that if your body is used to the excercise, then it is fine to continue it throughout your pg... The only thing is to watch your heart rate, I think you are meant to keep it under 140bpm, which means taking it easier in some classes I guess. We have a woman who is over 35wks pg at our gym, and she is still coming to RPM and Body Pump classes! :shock:
