Can we get a Topcat nutrition/core thread?

[FearTheLoss]

Just saw Topcat's core in another thread, the dude is ripped.

What do you do for core topcat? and what kind of nutrition plan are you on?

I have an athletic build and a strong core, but I can't get my abs noticeable like I want them too..it's like my skin has too much tissue, because I'm not fat...thinking a diet change, or maybe adding more sprints to my workout could help this.
