AFAA GFI case studies

AFAA GFI · Put your knowledge to work in context.

The AFAA Group Fitness Instructor (GFI) credential is a certification for people who lead group exercise classes - teaching movement, music, and motivation to groups in studios, gyms, and community settings. It suits aspiring instructors entering the field as well as current fitness professionals who want to add group instruction to their skill set. The exam is multiple choice and is organized around five content domains: group fitness instruction fundamentals; anatomy, kinesiology, and biomechanics; exercise physiology and energy systems; class design, choreography, and cueing; and safety, injury prevention, and professional responsibilities. Preparation typically combines study of these domains with practical rehearsal - practicing cueing, building class segments, and refining form - since the test rewards applied teaching judgment as much as recall. The AFAA GFI case studies are 5 cases and about 3,268 words.
