Latin dance is a beautiful dance, which needs to be combined with music to get a good feeling.
The center can't be in front or behind, only in the middle. If you still feel unstable, there may be two reasons: 1. You haven't got used to Latin shoes. 2. The heel is too high. You can't use too high shoes for beginners of Latin. Two points up to three points is enough. When you are better, change to a higher one.
The head movement is mainly "holding your head and shaking your head". This should be combined with body movements. With one foot in front, make a basic Latin stance (fractional position) and open your hands to make a basic hand position. Arm.
Turn your body in the opposite direction to your front foot, and then throw your head forward quickly when your body is almost completely twisted. Pay attention to keep your head, your eyes can only look at the back and front. Then throw your head quickly, but don't push too hard, or it will lead to accidental cramps in your head.
