Around us, more and more people begin to join the ranks of fitness. In fact, complicated work and frequent social intercourse have already begun to overdraw their health, just like the advertisements of many fitness clubs: a fitness club is the gas station of your life! There are many people who choose fitness, but the purpose and way of fitness are different, but in the final analysis, they are all for health.

There are all kinds of people who exercise in the gym, fat people lose weight, thin people gain muscle and girls get plastic surgery. Why doesn't the personal fitness instructor in the gym advocate fat people running to lose weight? Let's analyze it for everyone.

Knee joint is the most important load-bearing joint in the whole body, and it needs to bear 4 times its own weight when running at medium speed! If you are only overweight 10 kg, then your weight is 40 kg, which is almost equivalent to adding another person's weight. What should I do if I am overweight by more than 30 kilograms? 120kg load! If the joint bears too much weight, it will cause wear and tear and irreversible damage. It hurts when the weather is wet.

So overweight can start with walking or walking fast! When lying down, the weight of the knee is almost zero, and when standing up and walking, the weight of the knee is about 1 ~ 2 times. When going up and down a slope or stairs, the weight of the knee is about 3 ~ 4 times. When running, the weight of the knee is about four times. When playing ball, the weight of the knee is about 6 times. When squatting and kneeling, the weight of the knee is about 8 times.

For example, a person weighing 50kg will bear about 200kg on his knees every time he goes up a step. Therefore, the weight of fat people is relatively large, and the weight borne by knees is relatively large, so it is not recommended for fat people to run for a long time. Generally speaking, it is recommended to walk fast or practice climbing machines and elliptical machines instead of running.
