Which professional is most likely to conduct an aerobics class for adults?

A fitness instructor is specifically trained to lead and instruct individuals in various exercise programs, including aerobics classes. These professionals possess expertise in creating safe and effective workout routines, guiding participants through exercises, and ensuring proper technique to prevent injuries. Their primary role focuses on promoting physical fitness and wellness through structured group classes or individual sessions.

In contrast, physical therapists typically focus on rehabilitation and recovery from injuries or medical conditions, rather than leading fitness classes. Recreational therapists work to improve the well-being of individuals through recreational activities and may focus more on therapeutic outcomes rather than organized fitness classes. Exercise physiologists, while they do have knowledge of exercise and fitness, generally concentrate on developing exercise programs based on specific health needs, often in clinical settings. Therefore, the role of a fitness instructor aligns most closely with leading an aerobics class for adults.
