The day I saw that my running buddy posted on her DailyMile workout that zombies had been chasing her was the day I started looking for a new running buddy. Just kidding! But I did ask her what in the world she was taking about. The next time I saw her, she raved about a fitness and game app on her iPhone called Zombies, Run!. Turns out that’s just one of a new genre of fitness apps hitting smartphones these days: exercise apps that are more like games than workouts. Here are 5 of them:

1. ZOMBIES, RUN!

The Zombies, Run! website describes this app as an ultra-immersive running game. While you are running, a story is delivered to you via your headphones as orders and voice recordings. The zombies are coming! You have to run faster! When you’ve outrun them, you can slow down – and so on. Once you get home, you can build and grow your base with items you collected while on your run (like medicine, batteries and ammunition).

2. FIT FREEWAY

Fit Freeway is a retro arcade-style racing game that you control while exercising on a cardio machine. Simply set your iPhone or iPad on your exercise bike or elliptical and the game reads the vibrations from your machine. The front-facing camera reads your head position – just lean left or right to steer.
