Maximizing participation in group exercise classes is a priority for health and fitness facilities. Providing you with a positive and effective exercise experience is key to the success of the program. Generally, the larger the group, the harder it is for an instructor to provide individual feedback. Instructor to participant ratios are generally geared to the requirements of the target population.
Adults
If you are a healthy adult, cardiovascular or resistance training classes in medium to large group situations may appeal to you. According a survey conducted by IDEA Health and Fitness, Inc., large group classes are still popular at many fitness clubs. These classes may be led by one main instructor. Maximum capacity is limited by space and equipment. If an instructor is unable to move around the room and make modifications to accommodate beginning to advanced fitness levels, the class is too large.
Children
The American Fitness Professionals Association recommends an instructor to child ratio of 1:10, particularly for strength training. Beginners require close supervision to avoid injury. Practicing moves at a slow pace or with a light load will help the child learn proper form. The instructor should lead the class through a warmup of low-level activity or calisthenics and end with a cooldown that includes stretching. Children should be frequently reminded to drink water.
Seniors
If you are over the age of 65 years, classes should have less than 20 participants, according to ShapeFit.com. Senior fitness instructors need to observe all participants to ensure health and safety during exercise. If a class size exceeds 20 participants, an assistant instructor may be present to provide feedback during the class. Music volume should be low, and the instructor's use of both voice and hand signals will help participants follow the routine.
Special Needs
Small group classes are optimal for those with special needs. If you are pregnant, have arthritis, osteoporosis or another condition that may require special attention, an instructor ratio of less than 1:10 is best. It is always a good idea to let the instructor know of any limitations you may have prior to exercise. Your instructor can help modify exercises or monitor you more closely.
