Keep your hands still, put them on your head or chest or something, and practice twisting your ass.
Squat your feet slightly-keep your upper body still-hip front-hip left-hip right-hip back.
So your ass turns around, and all four directions appear in this dance.
Action essentials: squat slightly, the rest of the body will not move, and the waist and thighs will definitely move, but it is driven by the crotch, not by yourself. You can practice in front of the mirror. I hope the answer will help you.
