I had RNY in 2019. I have lost 83 lbs. I walk daily and started ab workouts, yes while walking, to try to firm up my stomach. To me it does not look like I have a lot of loose skin on my stomach and it feels hard not soft. I look 6-7 months pregnant still. I do carry most of my weight in my stomach area. I am almost at my "goal" weight I have set for myself. Any ideas on how to get rid of my "baby"? TYIA
