The Serve: Twist Versus Forward Rotation
Collapse

The least talked about of the 3 trunk movements is the Trunk extension and flexion, which is the jackknifing you are referring to. The flexion begins before contact and continues to after contact. If you watch Federer, he even brings his knees up some during trunk flexion.Last edited by seano; 09-22-2018, 06:31 AM.

From a Design Perspective: One Could be Aware of the Connectedness of Elbow and Shoulders Line without Realizing the Extent of Loose Motion from the Elbow Joint both Long Before and Long After the Hitting Zone.
I would like to apply this observation to the serves of Jack Kramer and Ellsworth Vines but am only examining the available films of Kramer right now.
Despite the prevalence of the oarsman's serve today-- so called by me because of the huge contribution from both legs-- there is an older way of serving that still may be effective and useful.
Am I the first person to think this? Of course not.
What I may offer however is a fondness for and belief in circling back to old tennis subjects again and again.
Note: The right foot lifts while going forward without turning for a short way. This indicates a lack of "twist" as defined for this discussion. It further indicates that the shoulders have started their cartwheel or somersault or rise-and-tumble even before that foot leaves the ground. The vertical rotation thus begins before the foot lifts and continues far beyond contact. Also contributing huge push is jackknifing at the hips. Hips press slightly backward as shoulders press substantially forward. Jackknifing by Jack. Jack and Jill went up a hill. So did ta and ha.Last edited by bottle; 09-22-2018, 06:42 AM.

Hero Worship and Mode Identification are not the same Thing
When I was in eighth or ninth grade, I played against Steve Crampton of Middletown, Connecticut, a player with a Jack Kramer serve.
Steve's serve carried some driving topspin that bounded very high every time he hit it. Neither David Peoples the Oakland script writer nor I could do much with that serve.
We all three were together our freshman and maybe sophomore year at Middletown High School. Our fathers worked for Wesleyan University. David went to Choate, Steve to St. George's Prep, I to Hotchkiss.
Despite plagiarizing in the St. George's literary magazine my story "The Dragon and the Candy Fag," Steve played high on that Rhode Island prep school's tennis team.
Seems strange in my own efforts to be coming around to Steve's and Jack Kramer's mode of serving a tennis ball.
Just tried it for the first time despite the therapy sessions I am about to undergo for trouble in my sacroiliac.
Great ease is possible in the way this serve can be delivered.

Steve stole my story. I'll steal his serve.Last edited by bottle; 09-22-2018, 04:46 AM.

An Anti-Hoption Screed-- Bring Back Taylor Dent

But I don't see Jack Kramer, in this next video, driving off of rear foot. He rather just skates it up in the air to start the tumble.

Serving in the Jack Kramer, Pancho Gonzalez or Don Budge mode for a similar reason of health is small potatoes compared to playing tennis with one's opposite arm.
Quite apart from all that, it produces a better net rush. Look at how far in Kramer is when he hits his first volley. (But note who the other player is-- the guy about to hit a second backhand. He liked to hit a first short angle slow chop off a high bouncing serve to his backhand, but maybe he didn't do that here--I don't know.)
Am I implying that the almost universal modern hoptioners are overly set in their way? Of course. What's the fun in being an old dude if I can't do that?
Note: The second video here shows what to do when you don't want to go into net-- left heel lowers to court.Last edited by bottle; 09-22-2018, 06:00 AM.

Keeping your front on the ground back then simply must have impaired the driving upwards element.Last edited by bottle; 09-21-2018, 01:18 PM.

Brian, I found this old Tennisone video, which also saya what you say, shoulder cartwheeling.
Your article really opened my eyes, because I have lately had problems with my serve due to too much body rotation vs shoulde over shoulder cartwheeling. I noticed how a better tossing technique (getting tossing arm way up and holding it uo) helped me get the shouder over shoulder movement and a better, more consistent serve.
Thanks again for your great article!

Thanks to all for the great input. Makes me wonder why I spent weeks writing the articles but in reality that process helped me organize a lot of the concepts in my own mind and improve the process of converting the information into coaching methods and progressions.
The serve is often compared to other activities especially throwing. To me it is a hybrid between pitching and purely overhead motions like the javelin (thanks Norman) because it combines shoulder internal rotation (pitching) with overhead non-twisting motion of the shoulder and forward oriented torso rotation (javelin) and elbow extension along with all four directions of wrist rotation - fascinating really.
I like the throwing up drill of arturohernandez and have done the same with balls and racquets although the latter can get a bit dangerous and expensive. I also believe that strengthening the core is very necessary (Norman) to the forward rotation transfer. It is a bit challenging as the muscular driven trunk motion is lateral (the cartwheel) so isolating the oblique groups is the key - I've used many medicine ball drills to work on this.
Finally, the tilt back leading to the torso lateral rotation (around the forward axis) should (if done correctly) reduce the strain on the shoulder in elevating the arm in the upward swing compared to other approaches.

Excellent video on the forward rotation of the body on the serve. The cartwheel or somersault rotation seems somewhat similar to what javelin throwers go through. Javelin throwers spend a good deal of time strengthening their abdominal muscles by throwing a medicine ball overhead using both hands. Do you believe this could help tennis players? Also, do you believe that by leaning the torso back and bringing it forward rapidly, a player can propel his arm and racket into the ball with minimal strain on the arm and shoulder? The player who seems to do this in a pronounced way is Stan Wawrinka.
Respectfully,
Norman Ashbrooke

I keep looking at the video and really appreciating its clarity. Turning the shoulders more to get a more diagonal racket trajectory makes sense. Great video.
