How to unlock the Master Jammer Extreme achievement in Zumba Fitness - Definitive Guide
From the main menu, go to Edit Player. From here you can change the difficulty to Easy, Medium, or Hard. You'll have to do zumbathon 3 times because the achievements don't stack. If you don't want to to dance for the routines, you don't have to. Simply set your Kinect up so that you can sit and or lay down while the game runs. This way you can do something else while you wait for it to finish. Zumbathon lasts one hour so it will take you 3 hours to get all the zumbathon achievements done. I watched tv while these ran to make it go by faster.
After the Zumbathon is unlocked, play this on any difficulty. Go to your profile and edit the difficulty. It should already be set to easy, although it doesn't get any harder (the moves register less as it grades you more strictly). The difficulties don't stack, so got to play each one.
You can't lose, so just keep waving the wand
