How to Fire The Extensors when Serving

[@cristiantascu]

I totaly agree with you Jim, on the serve the feet are pushing upward the entire body and at the same time, this causes the racquet to drop even more behind, stretching the shoulder and the back muscles even more. This is exactely called "the sling - shot effect, stretching and pre-stretching the muscles"

Hi Jim, I love your insights into strokes. I think k the 2 and a half count is valuable, all the way to three - the point of contact, when "extensors are fired'. I wonder if you'd consider a count that adds 'four' at the moment of contact, with relaxation and completion of the entire large "windshield wipers". I have used this with y students with very good response. One-two-two and a half- three- FOOUURRR! Let me know what you think. Best, Adrian

[@JPMcLennan]

Adrian - your beats are good - especially the "and" which Tom Stow used - in any event this is about rhythm and something non cognitive - Jim

[@FairwayJack]

yeah ...I like the concept and will try it ....reminds me of the golf swing where legs/hips fire first and the upper body follows

[@JPMcLennan]

Almost exactly like golf - and the famous Tom Stow taught tennis on the theory of golf - nearly all hits were constructed physically as 3/4 nine irons

Vic Braden,,, is the GOAT,, read his books,,,The knees only add 7 to 10 mph

Flexing the forearm extensors is called dorsi-flexion. BTW: Instead of pronation, I show folks how to go from dorsi-flexion coupled with radial deviation on the back-swing to ulnar deviation and palmar-flexion on the forward swing as I pull the racket forcefully across the body. I demonstrated this (12/11/2020) at West Orange Tennis. They invited me back to give a 1-hr seminar on 12/14/2020. I'll also be demonstrating new methods in serve footwork, which exploit (in part) the "fire up" strategy. Hopefully, the coaches attending will get fired up as I explain Newton's 3rd Law Action-Reaction.

Do you have a link to a video? Sounds interesting.

[@FredYang]

very good tip

[@tadurreddy5651]

excellent point

[@Mickey_McD]

Oldie but goody.

[@freddel8352]

Thank you for your videos!

[@ossamahkhan]

awesome explanation ! u rocks

[@krakou2]

extensors of wrist?

[@JPMcLennan]

Just the tricep and quadricep muscles

[@jawsjawsjawsjaws]

Actually, I think your timing is wrong. If you look at the pros. They fire the legs BEFORE OR AS the racket drops from the trophy position. You don't fire the knees when the racket is in the dropped position, as this is too late. If your still bending the knees as the racket is dropping the sequence is off. Fire the legs then drop and pull the racket up to contact The racket drops and pulls up in a liquid like like snap AFTER the legs are fired

[@JPMcLennan]

Jonas - my late sense of the knees is very telling as I probably use them less than I should or even for sure much less than I may have done years ago - sorry for the poor demo

[@monstertrucktennis]

I think you're right about the timing, but the overall concept of firing the extensors UP is pure gold Jim! So many players, even pros, want to hit towards the target instead of swinging up and allowing the racquet to flow up into the ball once the hand reaches peak. They are the pushers of which you speak.

[@JPMcLennan]

Jonas - it might be that as the racquet nears the dropped position then the legs fire which creates a stretch shorten cycle in the shoulder - but that becomes very technical - Jim

[@rafaelguzman2038]

when i do this,i hit rocket serve !!!

[@rafaelguzman2038]

im 3.5 player

[@HurstRon]

this makes a lot of basic sense...I'll try it
