Think of it as a game and feel comfortable. Serve as naturally as possible. Make a side position and hit the ball. When you open your body and hit the ball, You can’t hit the ball right. That’s why Toss is so important. Throw Toss from 12 o’clock to 1 o’clock. The slice serve is… You hit the ball 3 o’clock. (SlISHlNG) It’s bending to the left. It’s a slice spin. But slices are more likely to get caught in the net. So I don’t recommend second serve. Flat or slice for the first serve. I like kick-serve as a second serve. Like a forehand drive. It’s like driving in the air. Close it with your left shoulder so it won’t open. The impact is here. Your swing’s going to go out of here. Kickserve is to keep your swing out. That’s how you get in the backhand of the opponent. In short, the swing goes this way. Swing along the baseline. Then you can hit the opponent’s backhand side (T-zone). (Coach Demonstration) And you have to turn your wrist around. Swing outward. Try it. Swing out. (Toss goes wrong) You don’t hit it, you catch it. Even if it’s practice, you have to be precise. Now you’ve hit the slice. (Back of the ball) Kickserve should hit here. (Side the ball) You’re hitting here. You can’t kick-serve because you’re throwing Toss away. Put the Toss closer. Toss is so far away that it’s a slice. (For kickserve) Put the Toss closer. Close your shoulders and. Close your shoulders. Put up the toss here and put your arms up. Your body needs to be like this. You have to turn your body to get more energy. Park PD: You want me to twist my body like this? It’s slice. Now put the Toss in 1 o’clock. Imagine that Toss is going down towards 1 o’clock. It doesn’t change at once. (ParkPD Toss is very unstable) Park PD: My left hand is not good… My toss couldn’t be better. I actually have a problem with my left arm. (General standard) Left arm function is 30%. In terms of right hand, My right hand (usually) turns my wrist. But my left hand can only move this much. (Comparison between right hand and left hand range) I have to toss the ball with my hands out. I can’t turn out. So I have to toss like this. I have this difficulty in serving. So how is it now? Park PD: I’m nervous about Toss. There’s also this way. There’s a way to put the toss in. I’ll throw it from one o’clock, and then I’ll throw it from 12 to 11. It’s hard to hit the back like this. (Recommendations) Throw the toss between 1:00 and 12:00. That’s how you hit it. It’s about three o’clock. Not three o’clock from the side, but three from the back. You’re standing on your feet. So here’s how it feels to hit the back of the ball. That’s right. The ball went a little closer to the center. If you practice enough, you can serve with stability. It’s more important to hit it the way you want it than the strong one. You’re still open. Your body keeps opening, so your energy is dispersing. When you hit the ball, you should keep your body closed like this. Your body opens faster because Toss is far away. That’s right. The ball is going to the center. You did well. Outside, swing to 3 o’clock! That’s right! You swing sideways as your body stretches straight. Throw it to the baseline. Throw it along the line. Swing. When you open your body, your swing goes like this. But if you do this, you don’t have much energy. So throw it sideways here. (Coach Swing Demonstration) That’s right! Okay. First thing to watch out is to keep the Toss away from opening. If the toss is far, the serve is weak. You have to be careful of that. And if you throw the toss far away, the swing direction changes as well. That’s right. You’ve got a lot of strength in your shoulder now. You serve with a racket on top. Usually the toss goes up and the swing goes out. But you already have your racket on top, so I think Toss is nervous. Park PD: But I’ve done it in a common way, and I’m not sure. Park PD: It was difficult. (Park PD serv) I have a lot to care about, so it’s harder to throw the toss. So I’m serving with a racket on top. Even if I put my racket on, I can power my serve as much as I want. The first one was a long way off. The second one was fine. Raising the Toss closer can give you strength. But if you throw the ball far away, it won’t be hard. Toss is that important. If you practice Toss well, you’ll feel better, right? But if you want to serve and volley, (Toss) Just jump in front. If you go in, the gap will be filled. You threw it away. You can control it as you go in. Your serve was weak. You have to practice Toss a lot. You’re very nervous about Toss. Park PD: I’m more nervous than most people. I’ll practice until the Toss is steady. There’s no way. Let’s go to the ad coat and try it. It’s a little easier over here Any serve is easy. This is Park PD: I guess so. My shoulders are already twisted. Yes, it turns on automatically. It’s easy to kick-serve because it’s easy to throw outward. That’s right. That’s how you go in that way. Hit it further out. Park PD: The ball is going in the backhand direction. Usually, backhand is relatively inferior to forehand. You threw the toss so far that the tennis ball didn’t have power. Plus, it’s a slice. If you want to kick-serve, you have to hit the back of the ball. You hit the side of the ball because it’s far away. The ball is bouncing inside now. That’s right! It’s very powerful. (Uncle HO appears) That’s right. That’s how you stick it in the backhand. Now your serve is “fault.” Don’t mind ‘fault’ and get the hang of it. Ok there and I need this at the end of the serve. This one. This is a Pronation. Like this. Park PD: Pronation is difficult. (Describe how to make pronation easier) Just push the end of the racket. The pronation is really hard. But if it’s hard, I’m going to give it a push to the end of the racket. Just think about changing directions here. What I’m talking about is that you stretched out and became a line. You have the power to stretch up here. Imagine changing that stretch of power downwards. All you have to do is change the direction down like this If you just turn down like this, I’m getting the ball from the top. This is the snap.Pronation! Relax your shoulders, gather your strength from the top, and go up. You go up and you stretch out. and changes direction.
