Yes. If you have been doing yoga regularly before pregnancy, you can continue your routine—though there may be some poses that are not advisable to take. If you’re taking yoga for the first time, then a beginner’s class is more advisable to help ease yourself into the routine. Avoid extreme stretches after the first trimester. It is best to take a class that encourages breathing and getting in touch with your unborn child, ideally under an instructor experienced in prenatal yoga.
