Fitness

Fitness is the ability to meet or cope with the demands of the environment. Here, ‘environment’ means the situations and activities a person faces, including everyday life and sport—not simply their physical surroundings.

Fitness is the ability to meet the demands of the environment efficiently. Those demands vary: an office worker and an Olympic athlete need different levels of physical fitness. Improving fitness can also make everyday tasks, such as climbing stairs or carrying shopping, easier and less tiring.
