Final answer:
According to AFAA, a group exercise instructor should generally teach at one level higher than the ability of the majority of the class.
Step-by-step explanation:
According to AFAA (Aerobics and Fitness Association of America), a group exercise instructor should generally teach at one level higher than the ability of the majority of the class. This allows the instructor to challenge and motivate the participants while still providing modifications for those who may need them.
For example, if the majority of the class is at an intermediate level, the instructor should teach at an advanced intermediate level. This ensures that the class remains engaging and progressive for the participants.
Teaching at a higher level also allows the participants to work towards improving their fitness and skill level, which is an important component of group exercise classes.
