有没有想过为什么将SPEED添加到您的SERVE如此困难？在此视频中，Todd和Jordan展示了6个关键要素，可帮助您在SERVE上创建SPEED。通过这6个关键要素（深腿弯曲，肩部线圈，松紧握把/手臂，正确折腾，呼气和腿踢），您可以为SERVE添加速度和功率。尽管不是每个人都可以像约翰·伊斯内尔（John Isner）一样发球，但是我们可以比目前所服务的速度更快地提高球速。因此，让托德（Todd）和乔丹（Jordan）带领您完成如何将MPH添加到SERVE的旅程。

point 2 the emblem faces the back part !! i do not agree if i watch groth, karlovic , isner they never turn more then 30 degree !!!!!! and if you want to do that without forcing you have to change the stand of your feet * like McEnroe *
the rest of the video is ok
I'm never quite sure where contact is on the ball and do we hit down?
Thanks a lot for explaining step by step, correction every inch of whole process! Love it!
Please keep posting so good videos for beginners like me!
Merci beaucoup
Embelum?
Great lessons!!
the "right way" by the big guy is the wrong way cause he foot faults every time
1. keep your tossing arm up
2. watch the contact point the entire time
3. swing fast, not hard
Fantastic tips.
I’m platform. When I Have equal weigh on both legs at the beginning of the leg drive and toss the ball in front I tend to hit the serve long.
Help?
Excellent details. Surly I will passing on. It call a perfect execution and where you want place the serve. Just stay calm and relax during the serve.
Great tips and a well put together video guys but what would you say if your clients arrived and didn’t tie their shoe laces!! 😉
Excellent instructions
I am 1000% sure adding a leg kick does absolutely nothing to improve your serve. By the time they're telling you to do the leg kick, all the speed should be transferred to your upper body and your lower body should basically be limp. Like they said, it starts at the ground and moves up. That means the motion should start at the ground and move up through your body. Kicking your leg at the end might feel like it's doing something but it's definitely not. If you don't believe me, watch some slow motion video of pros. Their legs go back after contact due to Newton's second law (not because they're kicking it back on purpose).
Other than that, good video.
Loved this one! When to bend the knees was a great tip for me… now I just need to practice it a bit more.
Oops… "right way" at 10:13 is a pretty bad foot fault.
I don't know about the leg kick; I think arm pronation would be more critical.
8:00 why are your shoe laces untied?
Very useful video. The turning of the shoulder, for me, need clarifying. Are you saying get the ball toss in front of you quickly and then turn the shoulder? If this so, how do you get the ball toss to go sufficiently high? ( the high ball toss is not covered in your video)
