Answer 2

Salsa is a very popular form of dancing. In many styles of salsa dancing, as a dancer shifts their weight by stepping, the upper body remains level and nearly unaffected by the weight changes. Weight shifts cause the hips to move. Arm and shoulder movements are also incorporated. The Cuban Casino style of salsa dancing involves significant movement above the waist, with up-and-down shoulder movements and shifting of the rib cage.
