Forehand serve with left side top (bottom) spin ** 1. [** Characteristic **: The left side has a strong upward (downward) rotation force. When the opponent blocks the ball, it will bounce upward (downward) to the right. Generally, the player stands on the left side of the center line or serves sideways.] 2. ** Important points **: When serving, keep your stomach in and the hitting point close to your body; try to increase the swing range and arc from right to left to enhance the side spin.

It is conducive to aggressive attacks and is often used with fast backspin balls. 2. ** Important points **: Hit the ball from the front left side of your body, at the same height as the net or slightly lower; pay attention to your wrist movement; the first landing point should be near the end line of your own station. ** 6. Forehand spin and no-spin ** 1. ** Characteristic **: The ball is slow and has little forward momentum. It mainly uses similar movements to create rotation changes to confuse the opponent, causing the opponent to make a mistake in receiving the ball or creating an attack opportunity for himself. 2. ** Important points **: Do not throw the ball too high. When you turn the ball, swing the racket back and cut the middle and lower part of the ball. The more the ball turns, the more attention should be paid to moving your arm forward. When you can't turn the ball, reduce the angle of the racket back and increase the force of the forward push. In addition, newbies should also pay attention to the following general skills: 1. When you serve, you must coordinate all parts of your body, such as stepping on the ground, turning your waist to accumulate strength, and using your physical strength when you touch the ball. You can't just rely on your hands to serve. 2. Don't be anxious before you serve. Think about the possible means of receiving the ball after the serve and prepare for your third return. 3.

For example, the domestic sticky rubber had an advantage in this aspect. For example, the Golden Benteng rubber in the 729 Benteng series was suitable for the forehand. Its hardness was 40 degrees and its thickness was 2.15mm. The good stickiness could easily stick the ball and make the rotation easy. The sponge was free and was a high-density hard sponge. It was fast and strong. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
