Exercise, rest and proper diet are essential for physical fitness. Diagrams show the structure and function of muscles and the importance of exercise to tone muscles, nerves and organs. With rest, muscles are cleansed of wastes and refueled. Food, our only energy source, provides fuel for the body mechanism. If the physical side of the Health Triangle is weak, the other two sides can be adversely affected.
Physical Fitness and Good Health (1969) is currently not available on any services.
