Zumba is a fitness program
Zumba is set up by a Colombian dancer and choreographer from Miami (Alberto Beto Perez) and is based on Latin American dances (such as salsa, merengue and samba). At Zumba you do exercises on music (similar to aerobics). The name Zumba comes from Spanish and means ' fast moving and having fun '. Zumba is a registered trademark, so instructors must obtain a diploma and purchase a license to give lessons.
