For all of us who need more motivation to workout, I present to you this week's app of the week: Zombies, Run!

The app put you in a scenario that a zombie epidemic has hit the earth and only "a few have survived". In the story you are are a runner who is en-route to one of humanity's last remaining outposts.

You play the game by walking, jogging, and running around in the real world. You can listen to the story and your own music.

The app is free on iTunes, Android, and free to sign up to participate in the story. Currently there are 6 seasons with 39 missions. I have just started with the app so I am on Season 1 Mission 1! There is also a version of the app that helps you train for a 5K.

Disclaimer: Upon downloading the app will ask to access your music library and media library. Also, I am kinda obsessed with this!
