Zumba Fitness World Party

You just have to keep at this one. Don't get discouraged if the percentage complete doesn't increase. It goes up after each hour completed, but the game tracks each minute.

A helpful way of doing this is to go into goals and set a goal for 12 hours in one month, that way you can keep tabs on how long you have left.

I found a lazy way to do this. I picked a 60 minute full length class. I put a jacket on an IV pole and hid behind it and used my hand to start the game. After the game started I ducked behind a couch behind me so the camera wouldn't see me go off screen. The jacket stayed pink and the game played all the way through. If you do not have an IV pole (I work at a clinic) I bet a coat rack or maybe even a little fake house tree or plant would work. Also a tall oscillating house fan would probably work great. Be creative and try out some different stuff and let us know what you used in the comments.

EDIT: I put a vacuum cleaner in front of the camera and leaned into the camera and shook it until it stayed pink. This is something almost everyone has.

Using this method you could get hundreds of gamerscore in the game without ever playing. Here are other achievements you could get using this method.
