|You actually have a major muscles group here that all work together. The three muscles that make up your gluteal region are the gluteus maximus, gluteus medius, and the gluteus minimus. The maximus is pretty much the main muscle here because it's the biggest of the trio.
Your glutes are divided into three distinct muscles:The gluteus maximus - creates the shape of your butt. Besides being a big muscle, it's also really powerful as it aides in lifting our entire body weight. It works anytime you raise your thigh to the side, rotate your leg, or thrust your hips forward.
The gluteus medius is a highly functional muscle that helps with hip movement and should not be confused with the gluteus maximus. It sits along the outer surface of the ilium, near the pelvis, sometimes referred to as the upper butt.
The gluteus minimus is the smallest one of the three gluteal muscles, it lies deep to the gluteus medius muscle. The gluteus minimus is smilier to the gluteus medius in function, structure, nerve and blood supply. Its main function is hip stabilization and abduction.
