Jump rope! I am an athlete, and I need some space for running. Of course, it would be better to have a gym, but for ordinary people, it is useless to vital capacity without a certain amount of exercise. Besides, if you want to sing, I don't know what your voice is. If it is popular, I strongly recommend you to jump rope. The reasons are as follows: ① There is no need for a professional runway and no geographical restrictions. Skipping rope drives all the muscles in your body, which is beautiful. \ (o)。 O (╯□ ╰) O 4 skipping rope can be fast or slow, which will help you master the control of exhaling and inhaling, and it will definitely help your major ~! ! ! But if you run fast and slow, you will get angry and feel uncomfortable. The above is my personal professional opinion, I hope everyone will adopt it, and I strongly despise plagiarists ~ garbage people, I have copyright!
