This is for when you get bored with plain old walking.
Watch the guy in the background!
I'm amazed that people keep trying this stunt with so many fails out there on the web.
Someone please explain to this guy how to use the rowing machine!
The only thing you'll get out of this workout is a sore neck.
I get sweaty palms and butterflies just watching this kid. He's nuts!
She sure knows how to work that machine.
Who knew this sport even existed?
