You don't know athleticism until you've seen this 'American Ninja Warrior' work out in a T-Rex suit

Former "American Ninja Warrior" competitor Reko Rivera is showing off his impressive athletic stunts in a new video that's blowing up Reddit and Imgur.

What makes this video so special? He does the whole thing in a Tyrannosaurus rex costume.

The T-Rex costume really adds a certain something special. Here's a look. 

The video was only posted yesterday, but people are already paying attention to the athletic dinosaur. It was shared on Reddit late Wednesday evening, where it has racked up over 5,582 points and reached the number two spot on the front page. 

"It's the perfect outfit for Jurassic parkour," commented one witty Redditor.

"You may think you know funny," wrote one Twitter user about the dino vid. "But if you haven't seen this, then you really don't know. "
