Stomach is bumpy although I am a normal weight!

loveisblind1

I am a little under 21% bodyfat but I tend to gain most of it in my stomach. It is bumpy in the middle of my stomach. I look athletic everywhere else except my abs! I'm getting a little discouraged because I feel like my stomach isn't seeing a drastic change in it's shape. I do a lot of kettlebell swings, ab exercises, and cycling/running. I am only 26 as well. How many of you guys had this problem and has it changed for you eventually?
