Fast spinny topspin

Cristh Garrido Asked 13 years ago

Hi Alois and Pingskills

i am working in my fast spinny topspin, training and studying, and i research the technique of the chinese players, and i saw that they move his arm very fast, but with a initial position with the racket down of the knees...Is necessary do that movement or while i have a fast movement of my forearm doesn't matter which is my first position????

Thanks
