Zumba Fitness World Party

Each song in the game is classified as either low, medium, or high intensity. Note that this doesn't have any bearing on difficulty/complexity of the dance though. It's purely related to how much you'll be moving.

These achievements unfortunately do not stack, so you'll need to get five stars on three different songs for this achievement. There is also unfortunately no way to see the intensity of a song, at least in World Tour mode. Even so, all of the songs (even the high intensity ones) are repetitive by design, so you can learn and dance along easily. Because of this, getting five stars on songs will happen naturally, and often first try. As long as you can keep your energy up, getting five stars on songs won't pose any problems for anyone.
