Generally speaking, sports training and promotion should follow the following rules: practice-feedback-modification-practice, and then promotion. In fact, it is very dangerous to improve badminton without a coach. There are three reasons. First of all, you don't have a standard to measure whether your behavior is correct or not. Badminton serves relatively accurately. The higher the degree of confrontation, the greater the role of power transfer. Why do the movements of the world's top athletes all look the same? Because the technical action is labor-saving and easy to control. Without a coach, it is difficult to achieve "more (finding more problems) faster (modifying operations faster) better (improving operations) and less (saving time and effort) in the feedback process. "This standard, because the relationship between bystanders is very clear, so it is difficult to pinch yourself. Secondly, it is easy to cause the stereotype of wrong action. All badminton coaches know that juvenile classes are better than adult classes. They are like white canvases. You let him do what you want. Adult classes are basically like badminton. They often play badminton to improve themselves. Although many technical actions are wrong, they have been done for decades, even decades. It's really hard to do! Once the wrong action is corrected, it is like repeating martial arts, and you can try to correct it later. Third, fixed training is difficult. Many times in badminton training, the coach will let you practice a certain subject for a long time. For example, this afternoon, I made several groups of high-altitude shots, then several groups of rubbing the ball, then several groups of killing the net, and then several groups of footwork. Although it is boring, it is the fastest. Turn the technical point of this action into your "muscle memory". Although the tactics of badminton match need to be changed by brain, every stroke is changed by muscle memory. In a word, it is unwise to give up guidance. Of course, the premise is that you want to play the ball well, to what extent? At least in the average second-and third-tier cities. If you just want to be an outdoor god, don't read this answer. Cold water overflows, so do something. Of course, you said that you are not qualified to hire a coach, and there is no time or economic reason to understand, but at least, please hold your thighs tightly and don't do strange tricks 50 years ago, but only those who have a sense of ball are surprised. Find a more regular movement and learn at least one at that time. God is the best. It's great that he can tell you what happened when you were wrong. Then, when you practice by yourself, watch the video first, watch the video, watch the video! Recommend Expert Pulse, move frequently, explain clearly, remember the main points of action, and practice to grasp a key point. You can take a video of yourself with the camera a few times before to see where it is done well or badly. Note that this technical action will forget the situation of OT. Her technical moves, and then if you do it right, you have to do a lot of practice to swing in the air. You can take the ball after the fixed action, but it should be noted that even if you practice shooting in the air, you may not be able to change your action after accelerating. It's best to find a partner to practice with you, let him stand opposite you, point out each other's mistakes and make a mirror for each other. Then it is very important to pay attention to the details, especially don't practice like Mr. Almost, thinking that you can pass the exam if the movements are basically right. The reason for badminton footwork and technique is often not how fast it is, but that the connection between rhythm and strength is very reasonable and it is very simple to set an example. Zi is the "leg pad" of singles. Many people seem to have correct technical movements and footwork, but the speed on the court is extremely slow, because they don't do this simple movement, which leads to the deviation from the rhythm of the track on the court. So do it thoroughly, or you'd better not do it. Find a benchmark, because you don't have a coach, you don't know whether you have made progress or regressed during this period, so before practicing, find a good player, list him as your goal, practice for a while, play with him, and then ask him, what do you think I have done, brother? Progress, where progress? Step by step, don't worry.
