Can a skinny kid get abs?
Visible abs are due to 3 things:
a. your dna; can't do anything about that
b. low body fat uncovering whatever is there; sounds like you are there already
c. doing ab work.
That said you won't know what "a" brings for you until you do "c". Not everyone is going to have the same big muscled look in the abs even with work, but you should be able to get the Ryan Gosling skinny guy visible rippling if you do abs work. Bicycle movement on the floor, jackknives, planks (front and sides), crunch and crunch machine (if yiou don't have spine/disc issues), and more a good trainer can show you.
