Common misconceptions in sports: if you don’t exercise for a long time, you will exercise hard when you have time.

Sudden large-scale and high-intensity exercise will make the body difficult to adapt, causing severe fatigue and soreness all over, and can also cause tendon and muscle strain, and even sudden death during exercise. The correct exercise method is to start with a small amount of exercise, a small range and simple movements, so that the body can have an adaptation process. After about half a month, gradually increase the amount of exercise and enhance the intensity of exercise, and the movements should be from easy to difficult, step by step.

These four fitness exercises, if you persist for a long time, have different benefits to your health.

Original content, those who carry it without authorization will be investigated!

Exercise and fitness is one of the things that we should insist on doing every day.

If you wait until you are old or have health problems before you think about exercising, it will be a little late. Although we can’t make fitness exercise as punctual as eating and sleeping, exercise can help us improve our resistance, reduce the body fat rate and maintain our vitality. Fitness is something that we all insist on doing.

For us, fitness exercise can not only strengthen our body, but also help us lose weight, improve our physique and physical fitness, help you improve your muscle strength, and improve every aspect of the individual.

If you neglect exercise because of your career, money may not buy health when you have health problems. Without health, your career can’t go on. Therefore, exercise is something that we need to persist in for a long time.

Everyone’s time, energy, ideas and adaptability are different, and there are different exercise methods in fitness exercise, and some people want to choose the best exercise method, but different exercise methods have different effects on our body.

For example, strength training can help you build muscles, and aerobic exercise can help you improve your cardiopulmonary endurance and break down excess fat. We should choose the exercise mode that suits us and make ourselves interested in sticking to it. For example, some people think running is good, while others think running is not good, which varies from person to person.

However, it is best to insist on diversification of sports. Don’t do a single sport, which is not only boring but also easy for the body to adapt. If the part of each training is too single, it is not conducive to their all-round development.

The following four daily fitness exercises are shared, and people who have time can do them every day. If you don’t have time, then choose 1-2 actions to exercise, in short, let yourself move.

1. Squat

As a golden movement in the fitness field, this movement can not only enhance the strength of the individual’s lower limbs, but also help the whole body burn fat and lose weight. Insist on squat training, enhance bone density, slow down the speed of muscle loss, and also slow down the speed of aging.

Squat is an exercise suitable for men and women, which can lift hips and thin legs, increase muscles and reduce fat. If you can insist on 50-100 squats every day, your muscles and figure will change greatly.

Step 2: Walk

Some people don’t like running, mainly because running requires a certain degree of cardiopulmonary endurance, and the process of running is too tired. Overweight people will hurt their knees and thicken their calves after running, so it doesn’t matter. We can take a walk instead of running.

Walking is also a kind of running, at least the intensity is relatively low. However, walking is less harmful to knee joints and the fat burning efficiency is slow. However, walking is more suitable for heavy people. Walk for an hour every day, and you can lose 5 or 6 pounds after one month.

3. Running

There are many kinds of running, such as jogging, running fast, running fast, etc., and the change of venue will also make you get different benefits and feelings.

People who insist on running will eventually fall in love with running and sweating. It’s uncomfortable not to run for a day. Although some people think that the process of running will be boring, the physical transformation of those who persist is obvious, such as your heart and lung function will be strengthened, your legs will become thinner and your body will become slimmer.

Running can not only lose weight, improve personal immunity, but also improve personal cardiopulmonary function. Many diseases that doctors can’t cure can be treated by running. Do you believe it?

4. HIIT interval training

HIIT interval training belongs to moderate and high-intensity exercise, which requires short training time and high fat burning efficiency, and is more suitable for office workers who usually have little time to exercise.

You can finish a training in 20 minutes at home, and HIIT can quickly raise your heart rate and put your body into a state of burning fat. HIIT interval training combines aerobic exercise and anaerobic exercise, which can reduce muscle loss. If you persist in HIIT for one month, you can obviously feel that your body’s energy and vitality have become vigorous and you can shape your body.

These four kinds of fitness programs are common in fitness activities. Keep doing 1-2 kinds of training every day. If you keep doing it for a long time, you will find that your body will get many unexpected gains.

Several common fitness exercises, which one has the best fat burning effect?

Original content, those who carry it without authorization will be investigated!

We know that to lose weight is not only to control diet, but also to strengthen physical exercise to improve the body’s activity metabolism and strengthen physical fitness, so that you can lose weight healthily.

However, there are many choices of fitness exercises. What exercise should you choose to lose weight in order to achieve good weight loss results? Let’s take a look at the common sports charts.See which exercise burns fat best:

1. Jogging

Jogging is a familiar sport. Jogging for one hour can consume 550 calories. However, it is difficult for people who have just started exercising to persist for an hour. Generally, they need to start with brisk walking and jogging, and then transition to uniform jogging training after a period of time.

Jogging can be done outdoors or on a treadmill. However, outdoor running will be affected by the weather. There will be more people running outdoors in summer, but there are often fewer people running outdoors in winter. Do you like running on the treadmill or running outdoors?

2. Skipping rope

Skipping rope is a high-intensity fat burning training, which can not only raise the heart rate quickly, but also effectively exercise muscles and prevent muscle loss. Skipping rope is not affected by the weather, only one rope is needed, and a small open space can jump.

Jumping rope only takes 15 minutes at a time to achieve the effect of jogging for more than half an hour. After skipping rope, the body will be at a high metabolic level and continue to consume calories.

However, rope skipping training is suitable for people who are slightly fat, and people with large weight base and high blood pressure are not suitable for rope skipping training because it is easy to induce health problems.

3. Swimming

This is a very popular summer exercise. People are buoyant in the water, which can avoid the pressure of heavy weight on joints, and people with large weight base can also train.

In order to lose weight, we need to swim to lose weight. Our body will consume calories in the process of overcoming the resistance of water. Swimming for 1 hour can consume about 650-900 calories depending on the speed.

4. Table tennis

Table tennis is a low-intensity sport in which two people cooperate. Middle-aged and elderly people can also exercise, which can improve the coordination of limbs, physical flexibility and improve obesity.

One hour of table tennis can consume 350-400 calories, and beginners can burn fat while entertaining. However, table tennis needs partners to play together.

5. Go quickly

This is a low-intensity exercise suitable for people with heavy weight. If you can’t insist on jogging at first, you can start with a brisk walk, which is not easy to give up and can effectively burn calories. Walking fast for an hour can consume about 300 calories.

Which of these aerobic exercises do you prefer?

It is not the exercise with high fat burning efficiency that suits you. You need to choose the exercise that suits you according to your physical fitness, so it is easier to stick to it, and you can achieve a good weight loss effect over time.

Education and population: 11.78 million college graduates versus 8 million newborns.

Education and population issues have always been two major concerns in social development. But this year, serious challenges have occurred in both areas. Because there are 11.78 million college graduates this year, but there are only 8 million newborns.

According to recent data, the number of college graduates nationwide is expected to reach 11.79 million in 2024, an increase of 210,000 year-on-year. This huge group of graduates will face fierce competition in the job market and the pressure of employment opportunities. In order to effectively meet this challenge, the Ministry of Education and the Ministry of Human Resources and Social Security held a meeting to deploy and take corresponding measures to promote graduates’ employment and entrepreneurship.

This concern reflects the government’s emphasis on the adaptability of the education system. When formulating relevant policies, the government may consider providing more training opportunities to ensure that graduates have the skills and knowledge required by the market. In addition, supporting entrepreneurial projects and promoting industrial structure upgrading are also key factors to create more employment opportunities. This all-round consideration shows that the government hopes to promote graduates’ better integration into social and economic life through multi-pronged means.

At the same time, however, another piece of information revealed by Qiao Jie, an academician of China Academy of Engineering, at the 2023 Frontier Forum on Medical Innovation and Science and Technology has aroused widespread concern. He pointed out that the number of newborns in China has dropped by about 40% in the past five years. In 2022, the national birth population was 9.56 million, and it is estimated that the birth population in 2023 will be about 7 million to 8 million. This trend has led to profound thinking on the population structure and the decline of fertility rate.

The decline of newborn population may have a far-reaching impact on society and economy. One of them is the further aggravation of the problem of social aging. With the decrease of newborn population, the age structure in society will become more aging, which may lead to a series of social problems such as increasing the burden of old-age care and increasing the demand for medical care. In addition, labor shortage may also become a serious challenge. The decreasing newborn population will have a negative impact on the labor market in the future, which may lead to the shortage of employment in some industries and fields, and then affect the overall economic operation.

These two aspects of information jointly reveal the multi-level challenges faced by China society. In order to effectively meet these challenges, a series of comprehensive policies and measures are needed. First of all, reform and upgrade the education system to meet the needs of economic development and cultivate talents that are more in line with market demand. Secondly, measures should be taken to encourage childbearing, so as to alleviate the problems of population aging and labor shortage. This may include providing birth policy incentives and improving parenting conditions.

The government, enterprises and all sectors of society should work together to form a joint force and formulate and implement targeted policies to ensure that education and population problems can be effectively solved. At the same time, innovation and the development of science and technology should be encouraged to promote the upgrading of industrial structure and provide a better growth environment for newborns. Only by comprehensive consideration and coordinated promotion can we realize the sustainable development of society and create a more prosperous social environment for the future.

A wise man doesn’t tell lies. You have read it all, so you don’t have to praise it or pay attention to it, but please make a recommendation and forward it. Thank you!

I am a college teacher, and I am willing to share the topic of education with you. The picture comes from the network, and the infringement is informed. This article is original and any form of infringement is prohibited.

Tencent Miha Tour heads-on confrontation! Who won the second chaos in 2023?

Hello, everyone, I’m Dr. X. With the official arrival of the summer file, our long-awaited 2023 second tour chaos has finally reached the white-hot stage of bayonet fighting. In the last three months alone, there have been more than 10 new second tours on the market, which are huge and very lively.

However, after a hand-to-hand combat, the result of the firefight was terrible. Except for Star Rail, which stands on the best-selling list, it seems that none of them can play. So, what’s the performance of these two tours recently? What is the specific reason behind the product rushing to the street?

Today, I will take you to make a mid-term observation of the battlefield and take stock of a wave of recently launched secondary games.

Collapse: Star Dome Railway

First of all, Lao Mi’s "Star Rail" is definitely a success beyond expectations. Before the launch of the Star Railway, many friends were actually wondering, it’s 2023, but Mihayou turned around and played such an old turn-based game. Can it really be done?

As a result, the people who questioned were once again beaten in the face, and Xingtie made about 5 billion yuan in the first month. Players originally wanted to see the drama of other manufacturers fighting the original god, but in the end it was old rice who came to sister battle himself.

As a Kryptonian who has been working full-time and has filled the abyss (chaotic memories), I still have some research on Xingtie.

The success of Star Rail can be summarized as follows: firstly, it inherits the basic disk of Mijia users, and on this basis, it optimizes and improves various minor problems next door, which is not liver-warming to play. Even the new version was sent to ten companies. He really, I cried to death.

Second, the role-building and plot performance of Star Rail go further, which is the core profit point of Mijia Game. At the same time, because it is a turn-based system, the skill design of the role can be more unconstrained.

Let’s just say that Jingyuan and Yinyuejun are not within my scope at all in terms of XP. But he meowed, the design was so handsome that he really couldn’t help but want to take it home.

Thirdly, if you have studied the battle of Xingtie in depth, you will find that its underlying mechanism is quite complicated. A seemingly simple round can be divided into several stages, and the judgment nodes of skills are also very particular. Therefore, despite the turn-based system, it has made a strong strategy and playability.

In May, I raised the problem of insufficient cultivation resources, which has been basically solved after the official activities have been intensified in the past two months. Therefore, although Xingtie itself was born with a golden key, it still broke through its own upper limit and achieved great success.

The seventh epic

Then let’s talk about the second winner, The Seventh Epic of the Middle Horse (E7 for short).

E7 has been on the line for more than a month, ranking ninth on the best-selling list. At present, 50 people are fluctuating up and down, and the score is still rising, which is considered stable. Moreover, the world arena, the core of the game, just opened half a month ago, and it is estimated that there will be some stamina to go up again.

There is no doubt that E7 is also successful, and even achieved a counterattack. Old X When I talked about E7 in video last time, most of the audience were cautious, indicating that the game was out of date. As a result, I didn’t expect it, but it became the best one except Star Rail.

And according to the news I got from my friends in Zi Long, they did a very good deal. In fact, E7′ s agent was signed as early as 18 years ago. At that time, because Korean games couldn’t get in, no one robbed it, and the agency fee was very low, so it was a big bargain. Can only say that Zi Long boss in business, is really a little level.

Aurora at White Night

Then there are two other medium-sized horses, Aurora on a White Night and Back to the Future, which I would like to call "Rucheng". That is, it seems that it didn’t work, and it seems to work again.

As "Aurora at White Night", which carries Tencent’s second-yuan ambition and contains a golden key at birth, it is really full in art vertical painting. I took these pictures as wallpaper after reading them.

But apart from art, Aurora at White Night is almost all short-board. Even the grid is like a hand rush, and it will wither immediately after a wave breaks out; The secondary flavor can’t be said to be absent, which is partial templating and almost meaningless; The domestic performance is only about 100, so I’m sorry about my background.

At this point, it’s all a failure, right? It’s really hard to say that "Aurora at White Night" has achieved one thing, that is, relying on conscience to help Tencent gain a kind nickname in the small circle-"Tengzi".

It is hard to imagine that "Aurora at White Night", which was born in Tencent, has actually become the most conscientious player in this wave. Some media headlines are directly, "Tencent has given a lesson to the domestic second tour operation?" 》

To sum up, White Night Aurora has achieved two things: the operation listens to people and the welfare is generous.

For example, if the player is tired of fighting and the UI is ugly, the game will be swept up and the UI will be redone. If there is any opinion, he will really change it. Recently, the role has been lifted out of the bug, but it has not been lifted at all, and everyone gives the highest-grade reward for nothing;

In terms of payment, the game itself has sent a lot of cigarettes, and various small gift packages have been designed, such as 2 yuan for 1 cigarette and 9 yuan for 5 cigarettes. In today’s two-tour world, which is often 648 to 50, it is quite cracked;

Faced with this situation, even if the player does not intend to pay sincerity, he will leave the game like a spare tire.

Therefore, from the results, although the income of "Aurora at White Night" is average, it has earned a drink and experience for Tencent and achieved a wonderful "Rucheng". Looking at the recent developments of the game, it is obvious that the project team is still working hard. Whether the follow-up can rise against the trend by word of mouth will be observed again.

Reverse: 1999

Compared with Aurora on a White Night, which earned a shout from the operation, the other "Rucheng" Return to the Future is completely the opposite, because the operation has lost half of its life.

In terms of packaging, Back to the Future is one of the most advanced and least-funded two tours in recent years. The plot and people of the main line are quite wonderful. Although I deleted it later, I still watched the video to make up the plot.

With excellent packaging, "Back to the Future" rushed to the third best-selling list when it was launched, which was the highest ranking except Star Railway.

However, I didn’t expect that after the highlight, the game was just like taking laxatives, and it directly plunged into a thousand miles, operating all kinds of illnesses to give players the whole job. The most classic is that "everything is as perfect as planned", which makes people wonder whether he is playing dumb or really stupid.

In short, it was originally in 1999 before it was launched, but it became a memory after it was launched. "Back to the Future" ruined the beginning of Tianhu itself, and I don’t know if it can be rescued later. It can only be said that this is also a kind of "success".

Forbidden area of dust and white

The last medium-sized horse, Dust and White Forbidden Area, unfortunately became the only clear loser.

Say this game has no advantages, right? There are also some. The large-scale BOSS war is really ok, with a strong sense of presence and quite exciting to play. But other than that, "Dust and White Forbidden Zone" is almost all a problem.

For example, game art is too picky. Because of the limitation of 3D level, the project team chose an art style close to the white model, which is full of plastic feeling. Many friends around me were dissuaded by this artistic style.

And the gameplay is still unclear. In the online version, a "bunker" was finally added, but the enemy’s excessive face-to-face melee and justice from heaven made this bunker equal to nothing, which was very tasteless, and it was easy to see that it was the result of compromise.

It can only be said that Xishanju did spend money but it didn’t work. It’s like when you want to play seriously and shoot, you suddenly find yourself dying.

If there is no other reason, it is that the step is too big and the egg is pulled. First, the team used to do "Twin Vision" and "Girl Coffee Gun", and they have completely zero experience in 3D secondary elements; Secondly, 3D two-dimensional+shooting is a brand-new field, with high risk, and success is a small probability event.

Don’t swim like Miha.

In short, except Dacheng’s Star Rail and Xiaocheng’s E7, this wave of players can basically jump. So, why is it so miserable? From an objective point of view, it is really because the second tour market is too big now.

Not only do you jump on the street on the line, but there are many others who jump on the street before going online recently, such as Other Boundaries, Time Series Residual Noise and Touring Trains. Either the data is not good, or the team is infighting, and the timing is lingering. The number of reservations is over one million, and it is still impossible. Looking back, it was a wise choice to cut down the secondary project at an early stage like Lilith did last year.

But aside from the objective reasons that the market is too big, I want to say one thing: I really don’t copy Mikhail’s tour hard for the next two tours. Without Jin Gangzuan, why do you have to take that porcelain job?

Cut through the recent wave of games, several models can see the traces of "copying Mihayou", and this kind of copying has led to various problems.

For example, in "1999", although the main frame is "Tomorrow’s Ark", it has copied the abyss of the original god, creating intensity anxiety for players when they open their clothes, and searching for resources. Who do players scold if they don’t scold you?

On the other hand, Tengzi’s "Aurora at White Night" only opened a permanent climbing tower in the early stage, and players can play whenever they want, without any pressure on players. Let’s just say we’ve reached a verdict.

There is also "Dusty Forbidden Zone", where the probability of drawing five stars from the role pool list is 0.7%, including the guaranteed rate of 1.86%, and 80 is guaranteed, but it is not written on the face.

I wonder if your family’s "Twin Vision" single withdrawal rate was 3% four years ago. How did it become like this four years later? Let’s put inflation here, right And the result? Players don’t buy it at all On the third day of the launch, the official found that the data was wrong, and it was too late to raise the level reward from 20 diamonds to 50.

Therefore, after this wave of lessons, the following products really don’t copy Mihayou hard. Many factors interact with each other, forming their own unique competitiveness. What’s the use of copying and paying or playing? I hope that the manufacturers behind will think clearly and adjust in time. You can also leave your favorite games in the second half of the year in the comments area to see which one is the most popular.

Spring sports: Do you know anything about badminton?

Spring is a season suitable for physical exercise, which can enhance physical fitness, promote body growth and metabolism. Badminton is a sport that is very suitable for spring.

The benefits of badminton

Badminton is suitable for men, women and children, and the amount of exercise can be determined according to one’s age, physique, sports level and venue environment. Moderate badminton can promote teenagers’ height growth and cultivate their excellent psychological qualities such as self-confidence, courage and decisiveness. The elderly and infirm can exercise as a method of health care and rehabilitation to achieve the purpose of stretching joints, thereby enhancing the functions of cardiovascular and nervous systems and preventing and treating cardiovascular and nervous system diseases in the elderly. Badminton requires practitioners to judge the ever-changing ball path in a short time and fight back decisively, so it can improve the sensitivity and coordination of human nervous system.

Badminton needs to keep moving, jumping, turning and swinging on the court, and reasonably use various hitting techniques and footwork to hit the ball back and forth on the court, thus increasing the strength of upper limbs, lower limbs and waist muscles, accelerating the blood circulation of the exerciser, and enhancing the functions of cardiovascular system and respiratory system. It is a decompression and relaxation exercise.

What are the weight-loss advantages of badminton?

Relatively speaking, badminton is easy to operate and its technical content is not very high. If you don’t pursue the level of competition, it is a very easy sport to get started. In addition to singles, you can also play doubles and mixed doubles, which is richer and easier to stick to than running and skipping in a single form. After all, you are not exercising alone. So if you want to choose a long-term weight loss exercise that you can stick to, but don’t want to choose running, badminton is a good way.

Matters needing attention in playing badminton

There are many back and forth movements and lateral movements when playing badminton. In order to catch the ball "steadily, accurately and firmly", the movement speed will be very fast. Such rapid movement is easy to cause ankle sprain. The ligaments around the ankle joint and the ankle joint capsule are damaged, which causes joint instability and joint pain, and severe cases need surgical treatment. If you don’t pay attention to long-term exercise, your ankle will be sprained repeatedly, which may turn into arthritis in a few years.

Badminton is an over-the-shoulder sport, that is, the wrist and elbow move beyond the shoulders. Over-shoulder time is long, which easily leads to shoulder fatigue. The impact between the humerus and the acromion may cause subacromial bursitis, medial humeral condylitis, etc. Therefore, there must be sufficient warm-up exercise before playing badminton, so as to avoid injury in high-intensity exercise.

Badminton has low requirements on time, place and physical conditions of participants, and has obvious fitness and sports effects. It is a sport suitable for national fitness. However, it is easy to sweat in spring exercise, so you should wear underwear that can absorb sweat and a coat that can keep out the wind and dissipate heat. Similarly, cotton socks that can absorb sweat should be worn on the feet, and sports shoes should also wear a pair of sports shoes that are warm and breathable. (Tong Zhi)
