I can not translate it but i think we might could help with backhand technique here in the forum. What do you wonder about the backhand? about the grip it seems like he is showing forehand and backhand grip? but i don not know why really, maybe that it is easier to play backhand with backhand grip.
it is too much to translate, why find a English version back hand video. Many good one on youtube
I want to have more explosive backhand. My current backhand is not explosive enough to score a point, just placement and slow spinny loop.
I want to know the ideal grip and the swing/arm rotation to improve my backhand further.
