How do I get shredded?

I'm looking for some advice on the most efficient and effective way to actually get visible abs!

You’re in the wrong sub. Check out "recreation and fitness"—there's tons of stuff about this there.
By the way, let's get real. You can build muscle in your core all you want, but those abs aren't showing up unless you burn off the fat covering them. That usually means hitting some cardio—running is probably your best bet.
