I don't know what kind of dance you are learning. Just wear comfortable clothes and bring a kettle to replenish water in time. If it is a big dance, it is recommended to stretch well and prepare a bottle of gold, fire clothes, Mahda, saffron and oil. Before exercise, you can apply a little soothing and activating meridians to relieve muscle soreness. It can also be used for falls and sprains, and bruises can be quickly eliminated.
