Which of the following is a common qualification for group exercise instructors?

Certification from a recognized fitness organization is a common qualification for group exercise instructors because it ensures that the instructor has met certain professional standards and possesses the necessary knowledge and skills to lead classes safely and effectively. Certification programs typically cover essential topics such as anatomy, exercise physiology, program design, and injury prevention, providing instructors with a comprehensive understanding of fitness and health.

While having a college degree in physical education could be beneficial, it is not a universal requirement for all group exercise instructors, making it less of a common qualification. The requirement for a specific number of fitness classes taught per month varies by facility and is not generally a formal qualification for the role. Lastly, a background in sports alone does not encompass the diverse skills needed for group exercise instruction; instructors must also have expertise in various fitness modalities that may not be directly related to sports.
