What is the main point of twisting the waist in cha-cha? How can I twist it more beautifully?
Don't deliberately do waist movements. All your strength comes from your feet. It's just a relatively fast dance, so you need to make clear the movements of your waist and feet, and then combine them step by step, so as to make it more beautiful! It's not that the bigger the action, the faster the better it looks, but the more natural it looks! If you want to be natural, you need to practice more, but be careful!
