1）抛球要稳定。要有一定高度。切记是肩部抬起手臂自然抛球，而不是手臂用力抛球。
2）击球瞬间应该像甩马鞭一样，让手腕自然挥动，而不是手臂用力。这样拍子和球接
触时间长，球的速度自然就快。
3）握拍象握锤子。击球路线是从左上到右下，这样会有甜点的感觉。发完球也会有桑
普拉斯或罗迪克的感觉：）
计划是强化这些感觉，然后争取提高成功率。还有很长的路。 | d******e

court rather than to the wall which is OK for FH/BH rpactice.
bcz, for serve, u need to practice 1st and 2nd serve seperately which are
totally different in tech, strength, spin, angle, etc. All these can only be
realized and experienced by the server on the court.
In my serve, as a 3.5-4.0 player, I alwasy toss the ball just at the height
of my racquet can reach its stright top position. I feel this low toss serve
is ea

learns the timing, rythm, coordination of body/arm/eyes, all crucial
elements for first serve too, which is not very different technically but
require better control of all of the above. This is important to develop
consistency and avoid injury (take me for example, I regretted that I did
not do what I just said) A lot of people may serve hard and occassionaly do
aces, but have no second serve - once they fails their first | p****4
发帖数: 517 | 4 The most important thing about serve is eye on the ball and do not lower
your head before the contact.
"take something off" for the second serve is the biggest misperception. Put
on more spin is the right way to add more control to the second serve. Never
think in your mind that you are to doubt-fault. Try to picture where and
how the ball will land.
The power of serve comes not only from the swing of your arm. It originates
from the court surface when you uncoil the bent knees. Turning your tru |
