This pose, also known as Supta Baddha Konasana, will open your chest and hips. It can also help alleviate any shortness of breath, a symptom that you may have during your first trimester due to rising levels of the hormone progesterone, as well as your third trimester as your baby grows and takes up more room in your belly.
