Product Details
✓❤Tennis swing training device: When exerting coordinated force, when approaching the hitting area, the slider is thrown to the top to make a loud impact sound, and the speed of the racket head reaches the fastest at this time. If the timing of the force is incorrect, the front and rear sliders will collide in the hitting area, and the force will not be effectively transferred to the ball.
✓❤100% Transferable to the Tennis Court: The skills you master practicing at home transfer seamlessly to the tennis court. Practicing for ten minutes a day can significantly improve any poor posture you have.
✓❤Product principle: The middle slider of the accelerator makes a crisp sound when it hits the top. Each type of impact has a specific impact time point. Determine whether the timing of the force is accurate based on the time of the sound.
✓❤Perfect Muscle Memory: This portable tennis trainer reminds you how to align your body with every shot so you can practice perfect muscle memory. This will naturally help you provide power and spin with ease on all shots.
✓❤Suitable for Everyone: Once you use our training system to feel the perfect balance at impact and the ability to hit the ball solidly, you'll quickly find that your shots become cleaner. From junior novice to tour pro.
