Hi Mike, Thanks for the comment and feedback. Keep me updated on your progress. Best, John

Agreed! I felt uncertain about putting the racquet on the side or behind the head, too. Thanks for pointing that out!@@PerformancePlusTennis

Thank you! Keep working on it and keep me updated on your progress! Best, John

Thanks for your feedback and great question. You should be able to achieve a good range of motion, even if you’re not bending your knees much. I would have to see your serve to help you, but I’m guessing there’s some other thing out of sequence that is limiting your Racket drop. Reply back if you’d like me to take a look at your serve. Best, John.

Thanks...let me know how your serve is coming along. Best, John

Thanks Jack. Happy Thanksgiving to you and the family! Best, John

Thank you! Kindly, John

Stick with what works for you...the simpler, the better! Kindly, John

sorry but what is the difference??

Abbreviated is like Roddick, Tiafoe, Rafter, Tomic, Wawrinka etc. Both arms go up pretty much together. Whereas players like Federer throw the racquet arm out and behind them before it then rises. @@pacoin51

Yes, I can definitely do a review on his serve. Thanks for the suggestion. Kindly, John .

You are welcome! Kindly, John

You mean the "Party Hat" idea? Well, it's a gimmick...some players probably would knock hat off, but I don't think Rune would! :-) Best, John

Yea party hat, just didnt recall the name of Party Hat, thanks =)@@PerformancePlusTennis

Thank you! Best, John

Hi, I don't think his placement / accuracy is at Fed's level...yet. But, it should be if he practices relentlessly. His clean movement has so much potential! Best, John

Thanks for your excellent question. The racquet drop is triggered by the upward drive and rotation of the shoulders. There is no attempt the make a swing...the arm is relaxed and the swing is a natural result of the body movement, much like the feeling of throwing a ball. The arm is a sling that throws the racquet into the ball. I don't see where is palm is facing up. This would be caused by the shoulder rotating back as you mentioned, and weaken his swing. I hope this all makes sense. Best, John

Hi David, Thanks for your great feedback and question, which is an excellent contribution to the video. The left arm (for a righty) plays an important role in the timing and control of torso during the upward swing to contact. In general, the tossing arm will fall toward the target, keeping the body in control and alignment as you rotate and drive upward into contact. Of course we see players like Murray, Thiem, Kyrgios, etc, presenting the left arm behind to the left at the end of the serve. But in every case you will see the left holding the balance on the right side prior to contact. Here is Murry: kzfaq.info/get/bejne/rJOAmbp2vdHLl6M.htmlsi=qsb6Kvuih0WiSzVB. Here is Aliasssime: kzfaq.info/get/bejne/iNx0ZpaU35nJcZ8.htmlsi=DGX5igooD9wRCB3O. So why throw the left arm back? Counter balance...it's that simple! I hoop this helps and makes sense. Best, John

Great, thank you!

@@dwienner4 Thanks David! Kindly, John
