What is Physical Fitness

Physical fitness is the ability to carry out daily tasks with vigor and alertness, without undue fatigue and with ample energy, to engage in leisure-time pursuits and to meet the above-average physical stresses encountered in emergency situations.

The level of physical fitness can be influenced by regular, systematic exercise. Moderate activity will maintain the individual at a level that is usually adequate to handle ordinary stress. If the fitness level is to be improved, it is necessary to participate in intensive exercise that overloads the physiological systems and thus promotes change.

Exercises that demand total involvement improve and maintain fitness most effectively. Jogging, running, swimming, vigorous dancing, cycling, and brisk walking are important types of exercises that influence fitness..

Normal, healthy individuals may plan their own exercise programs. The general rule is to exercise till discomfort is experienced like.until breathing becomes labored, or sufficient fatigue is observed. People with health problems like those who have suffered heart attacks, strokes, and other illness should see a physician and exercise under supervision.
