The simplest bouncing moves are: leg moves, twisting moves, hip moves, hand moves, head and chest moves and so on.
Jumping time, as long as with the beat of the footsteps on the line (commonly known as step on the music, step on the drums), the beginning of the first step of a beat: a leg slightly raised, while the supporting leg is slightly bent, and then will be raised leg down and gently stomp on the floor, along the trend of straightening the legs, which happens to be the end of a beat; and then exchanged into the other leg to repeat the above action, that is, the completion of the second beat of the action.
The main thing is to follow the beat of the music (mostly fast), the body slightly rocking back and forth or side to side, can add a little hand or leg movements, pay attention to do not get into a cramp suit.
If you are a professional lead dancer, your teacher will teach you a few common moves, and you can add your own stuff on top of that! If it's a big group of friends going to have fun together, most of the ones dancing inside the dance floor are not the ones who can dance.
Everyone is following the rhythm of the music and jumping (twisting their bodies), venting their own dance, you can see how others are jumping, and then you think about how you want to jump on how to jump, because no one will tell you that you can't dance on the dance floor.
