The butt has 3 main muscles: the gluteus maximus, gluteus medius, and gluteus minimus. They all work together in order to enable us move our upper legs in all directions.
Amanda says that: "Every time you take a step, you're using your glute muscles. That's why we have glutes. Their function is to allow us to run, walk, squat and move. You're working your rear end all the time."
