Group fitness instructors organize and lead group train classes, which may include cardiovascular workouts, muscle strengthening, or stretching. Some instructors create a routine or select exercises for participants to observe, they usually then select music that is applicable to the movement. Others teach prechoreographed routines that have been created by fitness companies or organizations. They might lead courses that use specific train gear, corresponding to stationary bicycles; teach a particular conditioning technique, corresponding to yoga; or instruct specific age teams, such as seniors or youths.
