The term 'Squat Muscles' refers to the muscles used when performing a squat exercise. The primary muscle group involved in this exercise is the glutes, which is a six-letter word. The glutes are a group of three muscles located in the buttocks region, and they are responsible for hip extension, abduction, and external rotation. Squatting is an important exercise for strengthening the glutes, as well as the quadriceps, hamstrings, and calves.
