Fitness training refers to all kinds of physical exercises to improve physical condition, improve the control ability and performance ability of human body's good shape, and is a basic physical exercise with the purpose of improving health, strengthening physique, shaping physique and cultivating temperament.
1. It can improve nervous system and brain function.
Physical exercise is a kind of stimulation of the external environment to the body, which has the characteristics of continuity, coordination, speed and strength, and makes the body in motion. In this state, the central nervous system will mobilize all organs and systems at any time to coordinate and cooperate with the work of the body. In addition, physical training requires quick and accurate movements, which should be completed under the command of the brain.
The brain is an advanced part of the central nervous system. In physical training, the brain, spinal cord and peripheral nerves should establish fast and accurate reactions, and the brain should correct wrong movements at any time and store information of fine movements. Through constant stimulation, people's understanding and memory ability are improved, and their brains are smarter. Therefore, regular physical exercise can strengthen the working ability of nervous system and brain, improve nerve activity and make it healthier and smarter.
2. It can improve the function of cardiovascular system.
The cardiovascular system consists of the heart and various blood vessels, and the closed pipeline system powered by the heart is also the blood circulation system. Physical training is accomplished by the movement system and muscle movement. The exercise system consumes a lot of oxygen and nutrients when it works, but also discharges a lot of waste, and constantly supplies a lot of fresh oxygen and nutrients while consuming. This arduous task can only be accomplished by the closed pipeline system in the body-cardiovascular (circulatory) system.
When the muscles exercise vigorously, it can reach 5-7 times of that at rest, so that the myocardium is in a state of intense contraction. Frequent stimulation will thicken myocardial fibers, atrial and ventricular walls, increase the volume of the heart and increase the dissolved blood volume, thus increasing the strength of the heart. Due to the increase of myocardial strength, the blood injection per stroke increases and the number of heartbeats decreases accordingly. In a relatively quiet state, the heart can rest for a long time, thus reducing the workload of the heart and keeping the heart young forever.
Correct the body
Everyone's body has its own unique charm. How to explore the unique advantages of the body to make up for the shortcomings? Why the dazzling variety of training courses and traditional training methods, aerobics, yoga, equipment and so on are not good. Really change physical defects in the market? Can not really change hip sagging, body fat relaxation, waist thickness, curve circumference is not delicate and so on. Change some skinny beauties, but the waistline is not concave and the "S" problem cannot be highlighted?
In fact, it is impossible for us to fully meet the standards of modern models from birth. For example: thick waist, even if we lose weight, the waist line ratio remains the same. It is impossible to lose weight for these defective parts, but it is consumed together with other body calories. In the face of all kinds of methods to lose weight and improve body shape on the market, I think there are some drawbacks, and it is impossible to completely correct body shape. For example, aerobics may burn fat and lose weight, but it can't achieve good results for local improvement of physical dissatisfaction. Moreover, the single jump is explosive, which even leads to a large muscle mass, losing the slender beauty of female muscles. Although yoga pays attention to breath, internal adjustment and physical flexibility, I think the training method is too slow and single.
If the training of weight-bearing equipment is only to increase the difficulty of training, so that you have a "sense of training" and feel that money is not wasted, it is better to simply throw it away. It will not make the posture straight, but will aggravate the curvature of the spine. For example, when I was teaching students, I told them to kick their legs quickly because they had just finished pressing them, so as not to gain weight. But the student asked, "How can I lose my legs?" I replied that there was nothing I could do to make my legs thinner. I can only say that I will try my best not to let them grow thicker. After learning dance for so many years, I have developed my leg muscles. I don't think I can lose weight, but I can't grow long legs no matter how I eat.
For girls, over-developed muscles destroy women's slim, delicate and feminine beauty, which is not the aesthetic we pursue, while other aerobic fitness methods can only burn fat, but can't really improve their figure, and have no effect on the improvement and shaping of local lines. Physical exercise is not limited to women, but also a small number of men. Men can also change their rough and solid appearance and make themselves beautiful through physical exercise. In fact, the concept of real physical training is to change our own physical deficiency. As time goes on, it is difficult for us to avoid getting old.
