From this perspective, I spoke with Kelli Eisemann, who is 32 weeks pregnant with her second child. It seems that yes, it can but up to a certain point in the pregnancy.
In the video, Kelli explains that she had already been exercising before her first pregnancy and did not begin a new exercise routine while pregnant. I need to note that one must always speak with their doctor about starting a new pregnant exercise program. Previous to pregnancy, Kelli has experience in running, strength training, and high-intensity interval training. She explains the mental health benefits she gets from exercise pre-pregnancy and while pregnant.
