For the good looks of your body is not only necessary to work out several hours a day, in addition to exercise a very important way of life. Exercise is futile, if not enough sleep because the muscles are developed and strengthen at rest. Another important thing about a good-looking is the proper and healthy diet. It is recommended that you eat several times a day moderately. If we take all the necessary ingredients for our body proteins carbohydrates hydrates. Fruits and vegetables also as much cooked and fresh food.
In physical fitness, body composition is used to describe the percentage of fat, bone and muscle in human bodies. Because muscle takes up less space in our body than fat tissue, the composition of our bodies and our weight, determines leanness. Two people at the same height and same weight can look very different from each other because they have different body structures.
Cardiorespiratory fitness refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity. Regular exercise makes these systems more efficient enlargement of the heart muscle, allowing more blood to be pumped with each stroke, as well as increasing the number of small arteries in trained skeletal muscle, providing more blood to working muscles. Exercise improves respiratory system by increasing the amount of oxygen that is inhaled and distributed tissue.
Flexibility or limberness refers to the absolute range of motion in a joint or series of joints, and muscle length in excess of the joints. Flexibility is variable between individuals, particularly in terms of differences in muscle length of the more common muscle. Flexibility in some joints can be increased to some extent by training, joint exercises with stretching component to maintain or improve flexibility.
Endurance (also known as patience, endurance, durability, or) is the ability for people or animals to be made and remain active for a longer period of time, as well as its ability to resist, resist, and recover from the trauma they have immunity, wound or fatigue . In humans, it is commonly used in aerobic or anaerobic exercise. The definition of “long” varies depending on the type of effort – minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise. Training for endurance can have a negative impact on the ability to make power than if an individual undertakes training to counteract this effect.
Strength training is the use of resistance to muscular contraction to build strength, anaerobic endurance and size of skeletal muscles. There are many different methods of strength training, most commonly used gravity or elastic / hydraulic forces to oppose muscle contraction. See resistance training for information about elastic / hydraulic training, but keep in mind that the terms “strength training” and “resistance training” are often used interchangeably.
