Sal is a teaching pro and I met him at @newktennis although he’s no longer there.
He has incredible hands - it was amazing - and I thought that he was just “talented”. He just had “good hand eye” and “reactions” naturally. That I could never be that fast!
But I was SO WRONG! With a strong will and loads of practice - nearly ANYTHING is attainable!
Want fast hands? Just have someone hit hard at you while you are at the net. Over and over again. Believe me - I did it - and it works. I now have fast hands too!!!
