Real tennis can't be taught, it has to be devoloped inside, because it's an expression of the mind into the body, NO ONE can teach this.
So yea it's great to say "Hold your hand like this, or that", but no one can get bejond the basics of a 4.5 or whatever player by instruction, who taught Federer to be Federer? Case closed!
Again Mr. Miyogi was right in the movie franchise, "I give you roots, but real Karate comes out of you", same deal Tennis, tips for amateurs, I understand, but TENNIS IS A TRANSFERANCE OF THE MIND INTO THE BODY, anything else is BS for some to make money teaching nonsense.
PS: If you think you can be taught real tennis, I can teach you to be Robert Deniro!
