If you decide to do yoga https://www.julianalucky.com/post/mommy-and-me-yoga-benefits online, you do not need to take special courses in anatomy. However, it is definitely worth getting a general idea of how the human musculoskeletal system works, how muscles and joints work.
If you are taking an online program prepared for you by an experienced teacher, rather than an occasional online class, you will get to know your body through the prism of instructions, additional teaching materials and feedback within this program. A systematic approach to practice and possession of basic knowledge of anatomy will help you adjust your expectations from your body, accept its natural limitations, build a practice that takes care of it, without violence.
