The gluteus muscle, also known as the buttock muscles, is one of the largest and most powerful muscle groups in the human body. Synonyms for this muscle include glutes, gluteal muscles, and buttock muscles. Other terms that may be used to describe this muscle group include posterior hip muscles, hip extensors, and hip abductors. The gluteus muscle is responsible for various movements such as walking, running, and jumping. Strong gluteal muscles also provide support and stability for the lower back and pelvis. It is important to keep these muscles healthy and strong through regular exercise, including lunges, squats, and hip thrusts.
