"Exercise" author Daniel Liberman

In the new book "Exercise", the professor of Harvard University pointed out that even using a treadmill to exercise is also a function that has only been discovered recently. It has nothing to do with health and strongness when it just appears.

Similar to the treadmill, after being improved by the inventor William Cabit in 1818, it was used to punish criminals and prevent them from being lazy. The means of punishing prisoners in the British government include allowing them to walk on the hierarchical huge treadmill for several hours every day ...

As for whether the treadmill is still a "torture tool", people are sincere. However, in this era of modernization and industrialization, this divergent situation also reflects the absurdity of exercise.

Professor Liberman's research shows that "exercise is indeed not a pitch to maintain healthy and longevity, but through the history of human evolution, we can see that with life activity with life, it can significantly increase people's probability of death after 70". " Essence

Human philosophy is equally important as life philosophy. Each of us only has the opportunity to enjoy a better life. We don't want to be full of regrets due to errors in life, and this error also includes wrong use of ourselves.

Fallacy 1.

We have evolved the instinct of exercise

In particular, the most harmful consequence of the "exercise is a natural behavior" is: on the one hand, this society does not successfully teach people how to exercise, but on the other hand, it is unfair to humiliate and accuse people not exercise.

According to the exercise family, our ancestors of the hunting collector survived by walking, running, climbing, and various physical activities. However, exercise is only a recent phenomenon of human evolution.

In order to make up for the adverse effects of their laziness on the body, spend money to go to the gym to make myself sweaty, exhausted, and uncomfortable. If we don't want to be regarded as a lunatic or fool, how can we explain these weird behaviors to hunting collectors and farmers, or Gao Gao's parents?

Fallacy 2.

Lazy is an abnormal behavior

Keeping static as much as possible is the result of human evolution. Or more accurate, under the action of natural selection, our body will invest properly rather than excessive energy in non -reproduction activities including physical activity.

Please note that "as much as possible" to keep static. Obviously, if a person does not move, he cannot survive or grow. However, no rational adult hunting collector will only run for 8 kilometers for energy that wastes 500 calories for the purpose of making themselves happy.

Error 3..

In essence, sedentary is unhealthy

There is a very useful word Sitzfleisch in German, which does not directly correspond to the corresponding words in English. The literal meaning of this word is "the meat on the buttocks", which is used to compare the ability to sit for a long time in order to complete a challenging goal.

Therefore, if you are worried or guilty about your paralyzed sitting posture at this moment, please remember that your exercise ability is the result of evolution, and your sitting position is also the result of evolution.

Fallaine 4..

I need to sleep for 8 hours a night

Is it good to sleep for the body or the brain? Sleep is of course very comfortable, but I have a doubt about the following statements -sleep is a kind of adaptation evolved for the purpose of rest. During sleep, the slowing metabolism may be just because each organ can save energy more effectively in unconventional state.

In fact, we don't need to rely on sleep to save energy, repair tissues, and restore status, and we can do these things when we sit. No study has shown that 8 hours is the ideal sleep time. In most studies, people who sleep for more than 7 hours are shorter than those who sleep less than 7 hours.

Fallacy 5.

Ordinary people cannot achieve good speed and endurance

Everyone still attributes themselves to "speed type" or "endurance". However, each of us's correct cognition of speed and endurance has actually been blinded. The reason is that we are too concerned about those elite professional players.

You try high -intensity intermittent training -to change slow, not fatigue powder fibers to cause fast, fatigue leukomy fiber; stretch fiber slightly, which can increase the muscle shrinkage rate; Content, which can increase the strength of the muscle. If you want to run faster, you need to work hard.

Fallacy 6.

Evolution is to make yourself extremely strong

You don't like to consume time and energy in the gym, not just you, as well as those superheroes.

Spider -Man's power and abilities originated from a spider who suffered radioactive pollution biting him; the superpowers of Hulk and Captain America originated from scientists to transform their genes. Only Batman has obtained the ability to rely on fitness ... In most of the history of human evolution, too many muscles are more like a burden on the human body rather than an advantage. Whether it is the past or now, the strong level I want to achieve is the state that just meets the needs of my daily activities.

Fallacy 7.

Sports is equal to exercise

Sports is organized. From the perspective of evolution, individuals are attracted to participating in sports because of the excellent athletes, regardless of men and women, can always obtain a higher status and attract their partners by showing their strong abilities.

Compared to the ancestors, today's human body is weaker, not because we have reduced fighting during the evolution, but because the evolution allows us to fight in a completely different way: more active, use weapons, and more sports as a use of sports as a role as a weapon. Replace.

Error 8.

Only by walking, you cannot lose weight

In a room full of sports scientists, if you want to play with them, just shout "You can't lose weight". Then, remember to run quickly. As obesity spreads, two major opposition camps appeared on the issue of whether to lose weight.

This low -intensity to medium -intensity activities are relatively burning more fat, not carbohydrates. This is what the "fat -burning area" on some exercise equipment means. If a person walks for an hour a day and does not make any compensation in diet, theoretically, two years can reduce the amazing 18 kg weight.

Fallacy 9.

As long as you run, you will damage your knees

After the amount of running is too large, it will cause the juvenile and hip cartilage wear to cause bone arthritis? Studies have shown that people with amateur running habits are not more likely to suffer from osteoarthritis than those who do not have a running habit.

In fact, running and other forms of physical activity can help improve the health of the cartilage and protect the body's resistance. In addition to running, another factor that can reduce the probability of injury is the running posture. Many runners do not know what their running posture is.

Fallacy 10.

As you get older, it is normal to not love to move

The emergence of longevity phenomena is because human beings need longevity in order to work hard and take care of their grandchildren, or because the grandparents work hard and take care of their grandchildren, they get longevity?

A large number of studies prove the correctness of the following statement: men will not give up playing because they get older, they will only grow old because they give up playing. You must know that sweat flowing in "Changsheng Never Lao Spring". These sweats should continue to flow with our age.

Fallacy 11.

If you want to exercise, just do it boldly

We have to exercise to make up for the lack of physical activity, and exercise is just an alternative, unpleasant activity. Although doctors, coaches, and physical education teachers repeatedly suggest that we have to exercise, we usually do not adopt their suggestions. We need to stop self -deception, and don't say that exercise itself is a kind of fun.

If you have a resistance to exercise, a effective way is to tell yourself: it takes time to fall in love with exercise or less hate exercise. Because the goal of human evolution has never been lazy and ugly.

Fallacy 12.

A certain exercise project and a certain amount of exercise are most suitable for you

Some fitness experts, they do not do any cardiopulmonary training like a plague, and there are some devout aerobic sport enthusiasts. Even if you pay them, they will never touch the barbell.

Although exercise has such strange and trendy characteristics, the suggestions for exercise are nothing more than using some different professional terms: exercise for several hours a week, focusing on cardiopulmonary training, supplemented by strength training, and maintenance with age to remain maintained. Exercise habits. In any case, the negative impact of excessive exercise is smaller than the negative impact of non -exercise.
