Exercise and yoga

I would like to get into a good work out routine and yoga as well. I was VERY active before my first pregnancy but during the pregnancy not so much. After the pregnancy I started working out again, running, walking, lifting weights. This is my second pregnancy and I've been going on walks everyday for about 20-30 minutes but I'd like to get into better work outs, I know you can only do work outs that you feel comfortable with but I'd like to know what you do so I can try it out! Also some yoga positions for me to try! I'm not so flexible but I'd like to try to be😄
Any suggestions!?
