網球一問???

1) This is very dangerous. As you are not able to syn your racquet arm with your toss, and you are not able to coil-up your racquet at your back, if you still would like to swing hard onto the ball, then you highly have a chance to hurt your shoulder rotary-cuff. This is a very common injury in tennis. Now what you have to do is to synchronize your racquet arm with your toss, but don't try to toss the ball too high. As if you rely on higher toss, you can imagine when the ball free falling down and it is picking up speed by dragging down by the gavarity, and you only will have a fraction of a second when the ball traval to the optimal point of your racquet for impact. So, what you need to do is to practice more on your toss, to the right height at where your pointing up your racquet arm with your racquet, and that's is the most optimal height of your toss. This a very simple physic, and your toss come to the peak and it is stationary and you will have the time of the world to hit the ball. You can see most of the Pros are doing that, and this is most common and mordern way to make a serve.

2) In tennis there are many different kinds of stroke, what you mentioned, is what we call overhead smash. Actually, to us as an advance player, we actually have 3 choices to handle this kind of shot. a) we can take it on the raise, when the ball bounces up from the court then we will hold a semi / even full western grip and take the ball on the raise to drive a hard ground stroke to attack. b) if the ball bounced really high above to the height, some where similar to serving toss height, then we will do an overhead smash to try to finsih the point. c) if you are not at the above 2 level of skills, then we recommend you to make a step back, to adjust your shot approaching position, and wait the ball to come down and take it as a normal ground stroke. This will give you the most safe and require the least skillfull among these 3.

An I answered your question?

1. 舉定塊拍上去才拋波得唔得, 有D pro 如德國的Schudler 都好似係咁架咋

2. that is good, hit an Overhead. 個波唔夠高可屈少少膝
反而唔高唔低重難打(唁過頭), 要找教練幫幫手.

3. the best training partner !
