How can I put it? Physical exercise is a rigorous matter and requires a lot of knowledge. As for running, we should also know that running at different speeds and at different times has different physical exertion. For example, sprinting lasts for more than half an hour before you start burning fat. Fat people try not to run, especially jogging. Because the damage to joints is too great, if you really don't want to think about it, fat people are still the most suitable for swimming.

As for the gym, most people who go are fooled. After practicing with the annual card for several weeks, I found that there was little progress and ran away. Or for muscle beauty or strength, find a place to exercise and meet a girl or something.

Most sports that speed up your room use equipment. Because it is not gradual, it is especially used to cause permanent damage to the body, such as shoulder injury caused by weightlifting and spinal injury caused by "sports spine" such as barbell pulling. Bruce Lee tried, but he could hardly practice martial arts any more.

But now the gym keeps pace with the times (afraid of being eliminated by the times), and has launched sports that use its own weight, such as flat support, various push-ups and pull-ups. If there is no place to exercise, you can go to a place where you don't feel embarrassed.

If you want to improve your physical fitness in an all-round way, I suggest buying two books. The city is the gym and the prisoner's fitness. In particular, the book "City is Gym" is not for you to learn parkour, but for you to learn some physical exercise concepts and some common sense, which can guide you to get started. Tigers, tigers and other forums also have exchanges and learning. Of course, I suggest learning from cat crawling, which is always beneficial.
