Favorable effects on health, the individual and the collectivity of sport and in general of human activity are already known but scientifically proven when numerous studies describing the mechanisms by which good physical fitness exercise affects the human body functions and systems.
"European Sports Book”, in Article 2, defines sport as all forms of physical activity as follows:
-Expressing or improving physical condition (fitness) and good mental state;
-Formation of social relationships;
-Getting sports results in competitions of various levels.

Regular good physical fitness activity determine the maintenance or improvement of the structure from various tissues and organs (muscles, tendons, heart, etc..) Improves function and counteracts damage that occurs due to inactivity (sedentary) and aging. This is why in U.S., the term fitness defines physical condition, and the "health", the two words are almost similar.



When speaking of the apologetic effects of fitness it refers to both positive changes in the psychic, as well as the obvious and beneficial influence on some diseases of the best known back disorders (discopathy) or endocrine and especially cardiovascular disease. In practice, for the best answer to the action of physical effort, ischemic cardiomyopathy, should be the main objective of any exercise program, regardless of age, gender and whether the physical activity is an individual practice or under specialist supervision.

Beneficial effects:
-Cardiovascular system: increases the amount of blood that the heart can push, increases the amount of blood existing in vessels,, the blood becomes more fluid and flows more easily through arteries and veins (help atherosclerosis, coronary heart disease, hypertension).
-Pulmonary system: lung becomes capable to vent a larger quantity of air per minute (help chronic lung diseases).
-Skeletal muscle: increase strength, endurance and strength, muscle "melts" at a slower pace, along with the age  (fractures that occur in fall, the elderly);
-Body fat: total mass decreases from the visceral fat ass (help obesity);
-Metabolism disorders: increased capacity of muscle to extract (retrieve) blood glucose (helps diabetes)

Fat-metabolism: increases muscle ability to take fats from blood and use them to purchase energy (help arteriosclerosis);
Civil defense-organism (immunity): improves immune system's ability to respond to microbial attack (infection);
-Digestive processes: it improves the bowel movement, avoiding constipation (help colon cancer);
- Nervous System: improves reaction speed and timeliness of responses to various stimuli (help fractures caused by falls of elderly people);
-Cognitive functions: it improves reaction speed and timeliness of responses to various stimuli (fractures caused by falls of elderly people);
-Psycho-social behavior: improves the image of self, professional effectiveness, family behavior, and introduces the "well being" and the joy of living (depression and anxiety).



Fitness is not one and the same with bodybuilding! Many people enter the room and say they want to have large muscles like those of bodybuilders. Never going to happen this way. Use common bodybuilding exercises but different intensity and volume with which to work. Fitness means physical condition and includes: walking, running, pedaling, stretching, exercises on various apparatus, methods of relaxation and stretching, all done under the guidance of a professor of sports.
Do not be forced beyond the limits of your physiology. Listen to your body! This is my advice for those who begin fitness or aerobics.
-For starters, a few tips:
- Work at least 20 minutes per day (fat burning is installed only after 20 minutes).
- Choose a time when you know that you will not be disturbed by anyone.
- Do not work right after a meal.
- Drink plenty of fluids.
- Wear comfortable clothing.
- Ventilate the room where you work.
- Perform the exercises slowly, but correctly.
