Cardiovascular Fitness
It is the ability of the body to perform prolonged, large-muscle, dynamic exercise at moderate to high levels of intensity. This is dependent on the ability of the heart and lungs to deliver oxygen to the working muscles. As fitness levels improve, the body functions more efficiently and the heart can better withstand the strains of everyday stress.

Physical exercise is essential for the maintenance of normal condition of life. Lack of natural exercise is one of the chief causes of weakness and ill-health. In recent years, the need for exercise has been recognized even in sickness. Physiotherapy and occupational therapy are now standard procedures in medicine to restore the use of muscles and nerves that have been injured by disease or by accident. Patients with organic ailments are now advised to stay in bed for the minimum period considered necessary.
