It is certainly possible for a fitness instructor to work abroad, but you need to have basic fitness skills and knowledge and a fitness instructor qualification certificate wherever you work. Therefore, before going abroad to work, you need to improve your ability and have basic vocational skills. If you are not confident enough about yourself, you can go to a special fitness instructor training school for special training, or you can get some international fitness instructor certificates, such as ACSM certificate and ACE certificate. These certificates are highly recognized by foreign countries, and their gold content is quite high.
