I have a 4 pack but barely shows I don't have lines to seperate them yet. I swim do all ab work outs and make them harder and just started playing water polo for my Jr year
I'm 16 and I'm 6'3 I'm not fat, if anything I want to gain more weight my fat percentage is 4%I'm 150 and have skinny arms. What can I do to get the lines of separation and have my abs show more
