Generally speaking, we should move our waist and crotch. First of all, relax and let your waist and hips swing freely in a natural state. Remember, you are twisting your waist and hips, not your hips. Many people often mistake twisting their hips for twisting their waists. Practice around first. When your hips turn left, keep your body in the middle, don't follow to the left, and vice versa. Try to keep your upper body stable and don't shake. When practicing before and after, you can loosen your knee first, loosen your left knee, bend your left hip backwards, loosen your right knee and bend your right hip backwards, and then practice alternately. There is a special hip twisting movement in Latin dance, which is called splayed hip. Its movement direction is left front, left side and left back, right front, right side and right back, and it is the lying Arabic numeral 8, which is much more difficult. You can do simple exercises first, give it a try!
