My BMI is 20.56 so I'm barely normal weight and I'm trying to slim down fat I have on my abs but...how can I do this? I've heard lots of ab exercises help but doesn't that just tone the abs under the fat so it doesn't ever show up? Anyone have tips? Thanks!

I forgot to mention that I'm a guy and have a fast metabolism

Just fucking get off your lazy ass and work out. Go for a run, do some crunches and pushups. Eat some good food- whole grains, protein rich stuff (fish, beans, nut, w/e). And don't eat so much junk food.

Guess that works lol

do cardio 2-3 times a week
eat healthily.
cut your calorie intake that way when you're exercising your body will burn the fat off your abs for energy.

or...

you could just go to the local gym for like 1 hour and a half everyday worked for me.
