Im a freshman right now and i'm wondering what i can do to get a summer body fastest.

Im already in pretty good shape, but I really want abs because I have a little bit of a stomach. Im wondering how I can do this quickest. Here are the things ive already been doing the past few days to start

-Jog
-Eat less junk food
-Drink more water

If you have any other suggestions please tell me.


And please dont say it's too late or it'll take time because I really dont even care if its past summer when I do get abs but I'm not overwight ot even fat really. I just want to look good for the summer.
Im also a guy.
