The group of muscles we know as the glutes are the biggest muscles in the body. Located around the buttocks, they support the entire lower-body, and strengthening them can improve the stability of your hips and knees.
If there's one exercise that you should add into your workouts to increase muscle mass in the gluteal muscles it's the glute bridge. It's a simple exercise that you can do without equipment and, as well as the glutes, it can also help you build core strength.
