quote from TennisAsAlways One fundamental element that is very often times overlooked and forgotten is "proper balance". Projecting your weight into the ball at contact will dramatically add power to your shots. Sometimes people will shift their momentum forward towards the net/opponent, thinking that that will contribute to more power. But that's NOT always the case. 為了擊出球質，有項很基本卻也常常被忽略的訣竅， 就是適當的平衡。 如果在擊球的時候，同時轉移身體的重心， 將能不可思議的增加球的致量。 有人會將重心往前，轉向球網或是對手，並認為這將增加球的 power， 這並不完全正確。 Staying balanced is the key in producing those explosive shots. Rather than directing your weight straight ahead, have it moving into the contact point . Upon ball impact, make sure that your body is not up off the ground and or twisting and turning away from the contact point. 打出爆炸性的球質的竅門，就是保持身體的平衡。 而非將你的重量往前，或是往擊球點壓。 擊球瞬間，確定你的身體沒有離地，或是身體轉離擊球點。 (譯按: 此處我不太懂，因為我擊球有個甩身體的動作。 像鞭子一般，帶動手臂擊球。不知道是否就是甩離球點) There's a huge difference between forward towards the net vs forward into the contact point. Sometimes there will be instances when the contact point "may" happen to be towards the net, but it's not always that way. It all depends on the incoming directional angle of the ball relative to where you are positioned. 重心轉移向球網，及轉向擊球點，這兩個截然不同。 當然啦，有時候擊球點就在身體正前方，會需要往正前方移。 卻不是總是如此。 這取決於球的入射角 (譯按: XD ) 和你佔的位置。 Now I am not saying that you should not do an explosive FH like that of Federer's. He does leave the ground, but only AFTER ball contact. Everything happens so fast that it makes it look like the idiosyncrasies are the cause, rather then the effect. 當然，我不是叫你不要向 Federer 那樣爆發性的擊球， 他的確有離開地面，但只有在擊球過後。 只是他的動作非常快，所以看起來像擊球瞬間離開地面。 擊球後離開地面，看起來比較像個人習慣。 而非如此能夠打出爆炸性的球質。 Focus on balance, and see what happens. You don't have to crush the ball. Keep control of your swing, but just focus on the contact point weight shift + balance. 專注在平衡上面，然後看看發生了什麼事。 而不是像把球打碎般的暴力擊球。 記得， 控制好你的揮拍、重心移向擊球點、平衡。 --
