Personal fitness trainers work with an individual client or a small group. They may train in a gym or in clients’ homes. Personal fitness trainers assess the client’s level of physical fitness and help them set and reach their fitness goals.

Group fitness instructors organize and lead group exercise classes, which can include aerobic exercises, stretching, or muscle conditioning. Some classes are set to music. In these classes, instructors may select the music and choreograph an exercise sequence. They may lead classes that use specific exercise equipment, such as stationary bicycles.

Specialized fitness instructors teach popular conditioning methods, such as Pilates or yoga. In these classes, instructors show the different moves and positions of the particular method. They also watch students and correct those who are doing the exercises improperly.

Fitness directors oversee the fitness-related aspects of a gym or other type of health club. They often handle administrative duties, such as scheduling personal training sessions for clients and creating workout incentive programs. They may select and order fitness equipment for their facility.
