Body fitness is commonly understood if we examine its mechanism. In general terms the following are the basic steps to build a healthy body fitness program:

1. Cardio-respiratory endurance: the ability to deliver oxygen and nutrients to tissues, and to remove wastes, over sustained periods of time. Long runs and swims are among the methods employed in measuring this component.

2. Muscular Strength – the ability of a muscle to apply force for a short period of time. Chest strength, for example, can be precise by various weight-lifting exercises.

3. Muscular Endurance – the ability of a muscle, or a group of muscles, to sustain repeated contractions or to continue applying force against a fixed object. Pushups are often used to test endurance of arm and shoulder muscles.

4. Flexibility – the skill of moving joints and use muscles from end to end their. The sit-and-reach test is a good way of calculating flexibility in the lower back and backs of the superior legs. This is imperative for healthy body fitness as well.

5. Body composition is often measured as a component of body fitness. It refers to the structure of the body in terms of muscle, bone, vital tissue and organs and fat mass. An optimal relation of fat to lean mass is an indication of fitness, and the right types of exercise will help you diminish body fat and increase or retain muscle mass.
What you are trying to achieve will always depend on how often, how long and how hard you train, and what kinds of training you do.

These is directly related to your body fitness goals, your present fitness level, age, health, skills, interest and convenience are surrounded by the factors you should think about. For example, a training that is meant for high-level competition would follow a different program than a person whose goals are good health and the ability to meet work and recreational needs.
So, move away from your seat and get started with your body fitness plan!
