The gluteals to give the full name are made up of 3 muscles, the Gluteus maximus, medius and minimus. The gluteus maximus is the largest muscle and is mainly responsible for how are butts look which is why a lot of people concentrate on working this muscle to shape and tone the butt.
LOCATION OF THE GLUTES
The glutes are located at the buttock.
FUNCTION OF THE GLUTES
The glutes extend the hip joint so that we can walk run and jump. These large strong muscles bending and straightening the hip joint can give immense power for climbing or athletic performance.
If a daily job involves sitting for most of the day, (not forgetting how much time we sit at computers at home), the gluteals are not under any stress, meaning that they are not having to do any work and become weak which in time can cause lower back pain.
