In daily life, there can be many small games, which play a lot of roles in keeping fit. However, with the rapid development of society, many people in modern life prefer to sit at home. In addition to work, they also play mobile phones or computers and exercise for a short time. Compared with the past, we find that the amount of exercise is gradually decreasing, and there may be many people who don't exercise much all day. On weekends, they like to stay in bed. In fact, this kind of life has some negative effects on our health.

First of all, "it takes at least half an hour to lose weight by aerobic exercise." Many fitness instructors will tell their members that if you want to lose weight, you must do aerobic exercise for more than half an hour before your body starts burning fat. However, according to the actual fitness cases and some research data, fat began to consume energy after 30 minutes of exercise.

(less than 30 minutes, some studies think it is 20 minutes) began to participate in energy supply, but in the first half hour, it was not the main energy supply. Exercise for more than 30 minutes (inaccurate, the proportion of fat energy supply has a gradual increase process), therefore, the proportion of fat energy supply gradually exceeds 50%, becoming the main channel of exercise energy supply. Therefore, the fat consumption efficiency of rope hanging for half an hour will be different from that of 40 minutes. Because the execution time is extended by 10 minutes, obviously, the weight loss effect will be better. Assuming that the execution time is extended to one hour, the difference between the two will be very obvious.

The difficulty of actual physical exercise. In sports and fitness, as long as it involves long jump, it is a huge challenge to the heart and lungs. The real feeling is that the heart beats faster, and skipping rope is like this. A man who can run for forty minutes may not be able to jump on a rope for forty minutes. In addition, skipping rope also requires basic skills and ability. If the technology is poor. If your professional level is not high, you will often stop and come back, because the rope can't be tied on your feet, which objectively reduces the intensity of exercise. So most ordinary people will jump rope in groups for 30 minutes, and each group will jump 100 times. Of course, there will be a break between groups, and the actual working time is not 30 minutes.

It is worth noting that the actual consumption of total running energy for 40 minutes will also exceed the consumption of skipping rope for 30 minutes.
