Zumba Fitness

You'll get a lot of these while going for the other achievements in the game like the online stuff and zumbathon. Keep in mind though that if you don't wanna dance, you don't have to. You can just stand in front of the kinect or sit in front of it if it and it will pick you up. This way you can watch TV or do something else while the routine is running. Do 20 minute workout sessions on your down time and you'll get it eventually. I made sure to run one routine every day until I got my 30 days in a Row achievement and this achievement came along the way.
