Picture: Wladimir Klitschko and Arnold Schwarzenegger are having a pose off

We're not sure why, but there's a pose off going down on Twitter between Arnold Schwarzenegger and Wladimir Klitschko

Here's a sentence we never thought we'd write, there's a clothes off pose off going down between Arnold Schwarzenegger and Wladimir Klitschko, and it turns out they're both really big fans of each other. Klitschko is clearly a believer that you should have a fitness idol, someone who's going to push you on when you hit your limits in the gym, and as he says in his tweet, that man is Schwarzenegger for him. He even tweeted a snap of him doing his best impression to the man himself at the Stanglwirt health and fitness resort in Austria.

Ish ... . Lol. Trying to catch u since I'm 12. @Schwarzenegger #stanglwirt pic.twitter.com/YbPDnMxnxH

Schwarzenegger wasn't to be outdone though, as he replied back (although it took him a few days) with a picture of him next to his Klitschko poster pulling off a pretty good impression too, saying that he's a big fan.

.@Klitschko Great shot! It’s fantastic to see one of my favorite champions nailing my pose. Right back at you. pic.twitter.com/PDI3saXqM5

There are two of the manliest men going, so we're sure there's a very manly reason behind all of this, we just have no idea what it is. One thing we do know is we wish that both these guys had easier names to spell, this was a real nightmare on the spellchecker.
