I was doing a Pilates video for a while. I would Google safe indoor pregnancy exercise. Wish you well!
Yoga, theres a great 28min video on youtube with plenty of squats and moving meditations what bring up your heart rate if thats what your looking for. If yoy looking for something to just stretch out your sore body, as I also love and need, doyogawithme.com has about 4 great prenatal videos. One is 58mins and moves very slow which is great if you like the extra time. Or if your looking for something more quick they have a series of three short videos all of which work on different parts. Hope this helps
