Can I exercise at night? I am an office worker. It's almost eight o'clock at night when I come home from work. I want to keep fit recently, but I heard from my friend that it's eight o'clock in the evening. People must be reminded of the consequences of doing something, because fitness is a very tiring job. Don't believe in any quick-acting fitness online. What kind of muscle is so hard that you can't even pinch the skin? It's ok to exercise at night, but don't practice indirectly every day. Just spend some time doing something else. Practice for an hour or two, watch TV, take a bath and sleep, but rest during the practice. It can't last more than a minute, just like having sex. What happens when you pull it out for too long and then go in? Fitness must have side effects on bones. For example, after you squeeze something hard in the palm of your hand, many cells in your hand die, but don't worry that these side effects will affect your normal life. Your strong body and super immunity are not obtained in a comfortable environment, but you can't jog and warm up just after eating before fitness. The so-called warm-up is just running to your body to get hot or start sweating.
