Who says you can't do two things at once?
About one month ago, this man published a video of himself doing push-ups with one hand while using his other hand to solve a Rubik's cube. It's now starting to explode across the Internet. The anonymous bodybuilder/genius writes: "This is one of my first times trying one armed push ups so forgive me if the form is off."
This guy makes it look easy, but trust us, it's not.
By the way, if that wasn't fast enough for you, check out this guy's YouTube channel. He is the real deal.
