Pole dance combines dance and acrobatics centered on a vertical pole. This performance art form takes place not only in gentleman's clubs as erotic dance, but also as a mainstream form of fitness, practiced in gyms and dedicated dance studios. Pole dancing enthusiasts are of all ages; although many who perform this dance and acrobatic form are adults, that does not stop younger children from learning and performing in competitions. Amateur and professional pole dancing competitions are held in countries around the world.
