FITNESS 健身 The origin and development of bodybuilding Early in the time of ancient Greece athlete to exercise with lifting objects， and get a strong muscular body， the strong and handsome athlete， was caught sculptors "records" and survived to today. This is an early budding in bodybuilding. Late 19th century， the germans Eugene pioneered the road through a variety of beautiful gesture to show the human body， and laid the foundation for the development of modern bodybuilding， so he was recognized as "the founder of the international bodybuilding，" and "the first bodybuilder in the world" people generally think strong and handsome "early" is from 1880 to 1930， during this period. The end of the 18th century， Germany's big mountain sports house， concert hall in London made a sensation of social performance. His developed muscles and harmonious body， is a perfect artistic statue， made thousands of spectators， which created the bodybuilding. In modern times， the modern bodybuilding is show the characteristics of physical beauty. Strong and handsome man's standard is: tall and strong， muscular and balanced， round shoulder breadth arm， energetic， physical health， etc. Female bodybuilding standard is: the fit， the graceful， busty， shoulder round waist fine， smooth skin moist， etc. Bodybuilding should be combined with the beauty of mind， have a healthy beautiful heart， to have a healthy and good mood， can have health beautiful posture action and good behavior， only the beauty of mind， to have a really strong and handsome. As sports fitness， namely competitive bodybuilding， refers to the figure show bodybuilders will each to the judges， the judges according to their appearance in accordance with the extent of the aesthetic evaluation.

Well-known bodybuilder including Arnold Schwarzenegger， dorian yates， ROM. Buddha who， franco in Columbus， frank zane， lee haney， Ronnie Ronnie Coleman， jay， carter and Jackson deckers tower. The benefits of fitness One， the fitness function can improve the respiratory system and cardiovascular system. Scientific practice confirmed that the rhythmic deep breathing for a long time， can make human body breathing large amounts of oxygen， absorb oxygen if more than the usual 7-8 times， can inhibit the growth and reproduction of human cancer cells. Second long-distance running exercise also improves the myocardial oxygen supply state， accelerates the myocardial metabolism， at the same time also make cardiac muscle fibers became thicker， heart contraction force increase， so as to improve the ability to work the heart. Second， the fitness to strengthen physique， disease cure. Fitness accelerate blood circulation， harmful to the excretory system material cleaning effect， so that the harmful material is difficult to stay in the body and spread. Three， the fitness to feel better， happy spirit. Fourth， to cultivate to overcome difficulties， temper hard work perseverance five， improve memory. Georgia institute of technology， a new study shows that just 20 minutes of exercise every day can be increased by 10% of memory On female fitness In this era most people with thin for beauty， "lose weight" is the female's mantra and life goals. When hard to go on a diet for the female health damage and desire for food more， many people start thinking about new ways to lose weight: the health and diet， cultivate the habit of exercise. Such not only more beneficial to health， reduce the beauty of the body shape is more health and vigor. But when it comes to sports， a lot of girls will immediately associate "terrifying" muscle， worry fat is lost but became muscles， to exercise for weight loss blueprint from aborted， mill must stand up and say: "because the women did not produce testicular testosterone， so it is difficult to stimulate muscle growth like men， so practice muscle female concerns have been completely avoided. Example Now let's talk about what to do， the following is a list of a few movements， of course this is only a small part of， there are a lot of waiting for you to dig. Chest muscle push-ups Common exercise， the main exercise the muscles of the upper limb， waist and abdomen， especially the chest muscles. Push-ups major exercise with the pectoralis major muscle and triceps， also saw before exercise deltoid toe， muscle and beak brachial muscle and other parts of the body. Push-ups on daily exercise and physical education， especially in military physical training is a basic training Back muscles pull-ups His hands with a wide grip from is resting (palm forward) the horizontal bar， slightly wider than shoulder， two feet off the ground， two arms natural prolapse unbend. Action process: using the latissimus dorsi contraction force to pull the body， the moment the pause when more than the horizontal bar， still for a second， to shrink the latissimus dorsi thoroughly. Then gradually relax the latissimus dorsi， let the body slowly down， hang reply until completely， repeat again. Can bend the knee， cross two leg back， make body slightly and better able to exercise the back muscles. Inspiratory， sagging during breathing methods: pull on the body when the exhale. Shoulder Standing on two feet slightly apart， your back straight， arms perpendicular to the sides， hands grasping dumb bells Began: the side arm dumbbell to shoulder level， above the elbow peg-leg End: return to the starting position This action is mainly the deltoid muscle exercise in humerus. When hand lifting objects， deltoid muscle can accurate mobile hips in each plane. By changing the actions of the starting position (hand in your side， behind the hip or thigh front)， can be more effectively exercise the deltoid muscle The leg muscles squats After ready posture， inhale deeply and slowly bend your knees control squats. Squats in the direction of the knee joint with the direction of the toes， squat down to thighs parallel to the ground or slightly below the knee. If hip on the ankle， the next crouching low， neither necessary， easy create an ankle and knee joint injury. Squats velocity shoulds not be too fast， should grasp the rhythm， at least the next crouching speed faster than the speed of squat. Due to muscle time significantly elongated management effect， the longer the strength drop， the more the less vice myodynamia decline. So， weightlifter squat squat immediately after can lift weight， after he squats pause time doesn't necessarily can lift a bit long. Because of his squat immediately using the gluteus and femoral quadriceps muscles being stretched， increased muscle elasticity， enhance the muscle strength. The requirement of bodybuilding exercise， squat down to a minimum to keep 1 to 2 seconds， then squat. Although doing so on the weight of the smaller， but the lower limb muscle group's actual stress did not decrease， and relatively safer. Thank you for watching classmates and teacher. In the end，hope you become the best you can.
