There are five fitness components for good physical fitness.  The components are cardiovascular, flexibility, muscular strength, muscular endurance and body composition.

Cardiovascular is the ability of the heart, lungs, and circulatory system to provide the cells of the body with substances necessary to perform work for long periods of time.

Flexibility is the range of motion in a joint.  Flexibility is affected by the bone structure of the joint, the amount of tissue surrounding the joint, the elasticity of ligaments and tendons, and muscle tissues that cross over a joint.  Inactivity is the major contributor to the loss of flexibility.

Muscular Strength is the ability to exert force against resistance. This includes weight lifting or other activities with resistance.

Muscular Endurance is the ability of a muscle to exert muscular force for a prolonged period of time.  A good example would be running or swimming for an extended time.

Body Composition or percent body fat is the amount of fat in the body as a part of the total body weight.  Located under the skin is a layer of fat.  This fat can be measured by several methods to determine acceptable percent fat.  The ranges for body fat are twelve (12) to twenty (20) percent for women, unless over forty years of age, then it rises to twenty-four (24) percent.  The range for men is between five (5) and fifteen (15) percent unless over forty years of age then it increases to nineteen (19) percent.
