guys i had problems with my toss - until i played with my non dominant hand (forehand for half a year). suddenly my tossing arm became more controled, stronger and i barely make a toss mistake ---------- and i didnt work on this - i didnt do any drill just trained my left hand. now its stronger than ever. i dont say you should play with your non dominant hand - but you could do some exercises with it - to get rid of the erratic toss. believe my - my toss was everywhere.....
and i also started to use the short dolgopolov motion. i toss it a little higher though - as i like to have a little slower overall motion - the important point is - its a natural stroke, and i dont stop during it ever. but the biggest problem solver was that i dont go up with both hands at the same time anymore... first tossing and then starting the service motion has changed my tennis life.
i think we all should find our own way of serving and our own tossing height!
if only i would start playing tennis at a young age - i would maybe become a tennis coach - because i really like to learn about the natural approach to tennis. there are players who use the power from muscles nad there are players that use natural kinetic power and there are players who use both.
you see... thats what i am talking about. But I do it different. he says you should bring both hands together up - i stronly disagree - but this depends on the individual player and his preferred way of the motion. but I think either HE is blind or he didnt study Dolgopolov well.
Dolgopolov brings the tossing arm up first and then the racquet hand ---- i think this is far more natural - a left hand is not the mirror image of the right hand - they are separate - just think of a bass player - we are not SIMETRIC --- there is a lot to gain if you use non-simetric methods - if you are music instrument player or whatever.
Tossing arm up first and then the serve hand is a very efficient non-simetric way of serving i think. its the best. Fed does it - Dolgo does it - Sampras does it - ALL THE OLD GUYS DO IT. almost. Its the holy grail of the tennis serve!!
one note: if I would teach I would first teach a low toss serve without jumping! then when you are confident you can jump how much you want!
if this young boy can do it..... we can do it too:
but again , he brings both hands up together which i
dont preffer.
i just think for non-pro players its just ridicolous to toss far beyond you reach with your racquet..
