Don't forget that Mackenzie is a professional cheerleader, and her skills are impressive to say the least. In fact, this girl recently shared an Instagram video of herself "standing three to a full" (whatever that means), and our minds are blown.
Basically, Mackenzie can do three backflips in a row. We literally didn't even know the human body was capable of such a thing. When you watch Mackenzie's video, here’s a word of warning: you might be super jealous of her mad skills...and of her six pack.
Again, girlfriend gave birth almost five months ago and her stomach is like a washboard. Clearly she's made a pact with the devil (LOL, just kidding, we all know how Mackenzie feels about that dude).
Are you as impressed as we are by Mackenzie's talent? Call us crazy, but we're thinking this girl should enter the Olympics and make this country proud!
