A world famous physical educationist, Eugene Sandow, has very aptly said, "Life is movement, stagnation is death." 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 recognised even in sickness. Physio 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.
Exercise and Activity For corrective living, it is essential to differentiate between exercise and activity. While both are important as they are involved in vital physical movement, they vary in degree and benefits. Both employ the body in voluntary movement. Activity uses the body to a limited degree and generally to achieve a specific purpose. Exercise employs the body over the widest possible range of movement for the particular purpose of maintaining or acquiring muscle tone and control with maximum joint flexibility.
Activity requires less physical effort and often less conscious effort once the routine has been established. Exercise demands considerable physical effort and is more beneficial as mental concentration is simultaneously employed.
