When did you start working out?

I’m 7 months postpartum after my second c section. I’ve never been super active but I want to change that since I have 2 kids and want to be around a long time for them. I had a pretty great recovery and feel good. I’ve gained all feeling back and haven’t had any scar pain in a few months. I want to feel good about my mom bod. I breastfeed so I’m not super comfortable calorie restricting just yet. What exercises do you do? Good YouTube channels to follow?
