The first is to yourself. 1. Prepare your body. If you have good coordination ability, you are good at any other sports except running, and your success rate of self-study will be greatly improved. 2. It is psychological preparation. You should have firm faith and strong will, and endure boredom, loneliness, frustration and failure. Time to get ready. The time for you to start self-study is six months, and there is no upper limit. At least you should call this time. 4. Intellectual preparation needs strong self-study ability, imitation ability and execution ability. The second is hardware preparation. 1. Find a wall without windows, with a flat and hard space in front. You're not Djokovic, so it's much better than this. Don't buy introductory photos! Don't buy introductory photos! Say the important things three times! All the introductions are nonsense. Once you can fight, even against a wall, it is no longer suitable for you. How many tennis rackets do you sell a year and how many people are there on the court? You will know that what I said is true. Three goals. Balls are consumables. Start by buying children's little tennis balls. No shame. This suits you best. 20, in fact, 20 is a little small, especially in the first few days, and it is easy to drop. When you can hit 100 times in a row with this ball, you can change it to this, Tianlong 603. This kind of ball has three advantages: endurance, cheapness and slowness. The third thing to prepare is the teaching material. If you are based on 0, you only need to learn forehand now, and don't worry about the rest.

All the above are the needs of self-study, the most important of which is the first part, that is, yourself! The following are the advantages and disadvantages of self-study. Let's talk about benefits first. The first is, of course, saving money. Secondly, you will be very happy, and the entry rate is higher than that of the coach! ! Why is this? The reason is that those who dare to teach themselves must have confidence in their athletic ability. So these people are more capable than ordinary people, so the success rate is naturally high. There is another reason related to the shortcomings of the coach, which we will discuss in detail next time. This is the bad part. The first is vulnerability. Anyone who plays tennis will have an injury experience. If you don't play tennis well, you will get hurt easily. It is difficult for me to learn to take fewer detours, so injuries are inevitable. The second is that the time will be longer. If your time is precious, you need to consider the cost of self-study. Third, technological progress will be slower, because if you want to explore for yourself, you will have more chances to make mistakes, just like the cause of injury.
