belly still fat after tummy

I want to get rid of belly flab? how to do that?

I used to be a gymnast and I had a lot of ab muscle but I quit gymnastics for medical reasons. I didn’t work out or anything after that, and my ab muscle turned into fat. I’m still super skinny, but I have flab in just one area of my tummy. it’s not really on the sides, it’s just in the middle where my abs were. do I do a lot of cardio? do I do ab workouts? what do I do to get rid of my belly fat?

i wouldn’t do anymore ab workout since you already have your abs established but i would do some cardio, like running. start out slow though because you don’t want to get injured.
