In fact, if you really want to do sports, you can do it at home by yourself. I have been doing this for more than twenty years. If there is a big problem, it is impossible not to send it for 20 years, right? I always do fifteen to thirty minutes of exercise before taking a bath every night. If there is a huge problem, it will not come out after more than 20 years. Those who tell you there is something wrong are just looking for an excuse to avoid sports.
