After New Year, or when Metabolic Stretching summer is getting closer the gym is crowded with people. New promises, a new bathing suit to fit in or just regular exercising to stay in shape. Usually you have to stand in line for the machines or be at the fitness center half an hour before the exercise class starts, just to get a chance to participate.These scenarios happen just a couple weeks of the year. There are times during the year when motivating people to join the group classes is a challenge.
Because of this I believe many people get tired and find another exercise, unfortunately. I think the system needs to be developed to get people motivated for the group exercises and never have the feeling they won't be able to go because there is no place left.
It is up to every center to research the interest in different classes and if needed, expand the classes. Maybe some need to be cut down when others need to be more often. I do believe many centers I have been to have succeeded in finding a balance to get many people to every class and in the most cases, everybody who is interested. Supply and demand is a useful principle.
