How to get rid of belly flab!!!😣😣

I have a part of my belly that is super flabby and droops from where I had my son three years ago, I’m very self conscious of myself and before you tell me to “embrace my mom bod” I can’t, I feel disgusting and fat. I’ve tried but I just can’t. The worst part is I don’t mind my stretch marks or anything, it’s just my belly flab that I can’t stand! How do I get it to go away, a girl is out of shape so if you could give me some beginner exercises or something that would be great. My belly literally reminds me of jiggling jello.😒😂
