Some people use their bodies to swing their hips back and forth, which is wrong. Even if the center of gravity moves, it is not Latin. Of course, there must be physical cooperation when swinging your hips, but that's not the point. Let me talk about the essentials of swinging your hips. -Preparation: Keep your legs shoulder width apart, straighten your legs but don't lock your knees, spread your arms to both sides, retract slightly, raise your head and abdomen, and lift the diaphragm (how to lift the diaphragm? Just the abdomen). -Essentials of Hip Swing: While the left leg is forcibly straightened (at this time, the left knee will be locked), the left hip will be pressed to the left rear with internal force, the right leg will lean forward slightly with the rhythm, then the right leg will be forcibly straightened, and the right hip will be pressed to the right rear with internal force (at this time, the right knee will be locked), and the left knee will lean forward slightly. Swing repeatedly like this, coupled with the following of the center of gravity and the coordination of traction and swing of the upper body, after a period of practice, your crotch must be impressive. -Speaking of which, do you see what the point is? It is to straighten your legs and press out your crotch with internal force, not your body. The body just needs to cooperate with this action. Also pay attention to the movement of the center of gravity, otherwise there will be no unique taste of Latin dance. The swing of the crotch in rumba is the swing of the pelvis and buttocks caused by the straightening and bending of the knees. It is not a deliberate swing of the hips, but an internal force that squeezes the hips backwards.
