Pop is a basic action in poppin, not hiphop. Hiphop is another dance! Pop refers to the explosion point of muscle! Suddenly, the force is suddenly controlled! There is also an action called hit, which has a wide range of actions but is not as urgent as pop! Dancers often combine them when dancing poppin! Pop is difficult to practice. To achieve the desired effect, it takes three months to practice arm pop! Poppin is cool, I like it!
