Think you've got the ultimate leg workout? Think again.

Check out this dude in Russia. He's pushing back on a car because either A) Russians are nuts or B) the nearest Planet Fitness is a few hundred kilometers away in Chelyabinsk (it's a real city -- look it up). Whatever the reason, this guy's probably got leg muscles bigger than Barry Bonds head during the early 2000s.

But we're jealous -- we get tired just climbing on the StairMaster to turn it on.

This is some impressive stuff. He's like a superhero who, for some reason, is the only one not to appear in a Marvel movie yet. We predict that by the time Stan Lee sees this, Leg Man will have his own franchise.
