[Upright Squat] mainly exercises the buttocks and thighs. You can practice to shape your buttocks and tighten your thigh fat. From an upright position, lower your center of gravity downward until your thighs are nearly parallel to the ground. The buttocks should be pushed backwards, the body's center of gravity should be on the heels, and the direction of the knees should be consistent with the direction of the toes. Do 4 sets of 15-20 reps every other day.
