It's easy to own one's fitness while participating in a class: control the amount of weight you lift, pick the variations of movements to perform, adjust the tension on your spin bike, choose the incline on your elliptical, etc. Everyone does this. Many people cannot stick to a solo workout routine. These people benefit a lot from classes. Fitness classes provide many positive things: - relationships with instructors & other students - peer pressure to show up and work hard - regular schedules - prevention of injury from bad technique - variety of music and routine which reduces boredom - incentive to work hard to maximize benefit from financial expenditure Together, these things improve the quality of life for participants. Fitness classes benefit society. Someday, human society will progress to the point where personal fitness is an expected part of personal hygiene, like brushing teeth and showering. At that point, fitness classes will be universally available, affordable, diverse, and extremely engaging.
