Ive been a subscriber to Move Your Bump since my 2nd pregnancy (on my 4th now!) - the workouts are great, quick, engaging, and challenging without being TOO challenging. I’ve done them even when not pregnant. I think it costs about $15/mo
Fitness for Mamas on YouTube has videos for 3 workouts for each week of pregnancy. They are in her playlists as they are from a few years ago. But I've found them pretty good and they're free.
