Apparently, this whole zombie athletics thing is a trend. To wit, experience the audio wonder that is Zombies, Run! Yep, it's a workout app that tries to scare the crap out of you while you exercise. Or something like that. The video doesn't sell it as well as I think the creators intended. Seems a bit...safe, at least for the zombie apocalypse. Still, not a bad motivator to get out of the house.
A better rundown of the pertinent fact can be found here. And look--the app hits the iOS on Monday. Happy running!
