WATCH: 340 Pound Mountain From Game Of Thrones Throws Vicious Body Shot At Teofimo Lopez In A Boxing Gym

Source - Star boxer Teofimo Lopez took down Vasiliy Lomachenko ... but could he do the same to the 6-foot-9 beast from "Game Of Thrones"??

Turns out ... he couldn't -- 'cause the two traded body shots during an epic training sesh this week, and Hafthor Bjornsson, AKA "The Mountain," appeared to be the winner!!

The two put down the weights and decided to do the body shot challenge in the gym for some reason, and Thor (who's entered the celeb boxing world this past year) REALLY stung Teofimo.

The Video: 

I've said it before and I'll say it again, boxers are some of the craziest people on the planet. Like there is no reason these two should be trading body shots. None. The Mountain is a foot taller and two-hundred pounds more than Teofimo and yet they line up like they're the same size. Teofimo is actually giddy to get hit. It's bizarre. Here's another angle of The Mountain's punch so you can see the size difference..

You know it's real because he gets his whole body into it. And for what? A video? What if something went wrong? What if he hit him so hard he ended his career? I'm starting to sound like my mother but still, the risk just isn't worth the reward. Then again, Teofimo knows how to take a punch so maybe it wasn't that bad to begin with. All I know is that if this is how Teofimo is training for his fight in November, he's going to destroy his opponent. He was going to anyway, but this confirms it. Now here are some hjighlights from that time Teofimo beat Lomachenko in October of last year. Enjoy…
