Wikipedia
A ballet dancer ( fem., ballerino masc.) is a person who practices the art of classical ballet. Both females and males can practice ballet; however, dancers have hierarchy and strict gender roles. They rely on years of extensive training and proper technique to become a part of professional companies. Ballet dancers are at a high risk of injury due to the demanding technique of ballet.
