Hi Leann, Congratulations! So thrilling to carry a child. Trust me I know how confusing it can be. I did quite a bit of research so I could feel confident with continuing all my workouts which I have done minus a few modifications when belly starting growing more (back and front laying for instance). First and foremost check with your baby doctor and get a couple other opinions as well. If you don't have any risk factors and you were consistently fit and training prior to pregnancy they should tell you to continue. Heart rate, heat, impact and heavy weights are what doctors and research generally address. Make sure you understand this and make an informed choice based on this.
