9-21-20 Serves

A wise decision. As they say, you're only as good as the speed and attention grabbing powers of your first serve.
Haha, I actually make more first serves if I go for it more. Whenever I get tight, I end up missing more.

I think maybe the increased spin on the ball with faster racket head speed helps it from going long. Not sure though. If you're curious about what the double coil is, it is the coiling done when you rock backwards, plus additional coiling when rocking forwards again. A lot of people don't do this and don't reach their potential racket head speed.

Oh cool! I wasn't sure what you meant. I'm just copying the Kyrgios rocking motion and it helped up the pace on my serve.

Maybe one reason people don't do it is that they lack the flexibility to achieve that much coil. After all, we're not all as young as @MaxTennis.

The frame rate is slow so that only about two frames are available to show the approach to the ball and there is too much motion blur.

It looks as if your elbow is too bent for too long a time? Try to compare this point to serves in this video.

For single frame use the period & comma keys. To select a video always use Alt + Left Mouse Click, otherwise the video starts playing. Go to impacts and work backwards. Compare frames with most similar racket positions. You can go full screen and come back down and the frame stays the same. Similar camera angles give the best comparisons.
The first serve in the video shows interior shoulder rotation (ISR) of the server. Too bad the elbow shadows were not visible over a greater range. For ISR the upper arm bone rotates like a top. The serve at 11 seconds shows the angles of the arm & racket and their timing to impact very well. Compare to your serve at 1:13.

Search the Big L Position (HiTech Tennis) and see if you can find it in the ATP serves and in your serve. See Big L Position for ATP serve at 11 sec. Find your Big L Position. (Upside down L made of near straight arm and racket.)

In your case, compare the bent elbow to the elbow of ATP servers at similar racket positions. I also wonder why - if your elbow is bent, your forearm does not move to the left if you are doing ISR? But after impact it is easy to see the rotation of your entire arm. Are you rotating your arm mostly after impact?

If no ISR, stop and study it until you understand it.

You need a camera with high speed video, 240 fps, and a fast shutter speed to get less motion blur.

For a high level serve the upper arm should not be too high too the shoulder joint. Ellenbecker, in the video "Rotator Cuff Injury," discusses this issue and describes the angle of the upper arm to minimize the risk of impingement on the serve.

@MaxTennis jealous of your climate as always - we are done with outdoors tennis and easy access to serve practice till May...
You are quite staying in place and not tossing/leaning/launching/landing into the court that much. Is it conscious? And what are your thoughts on opening up by contact, some discussion recently to avoid over-rotation?
Still trying to figure out what a 9-21-20 serve is?
It's September 21, 2020 (any more spare seats in this train?)

I have problems controlling my toss, but it is something I've been trying to focus on more (landing inside the court).

Not sure about opening up by contact. I don't really think about that when I'm serving. I just try to make contact as high up as possible.

I maybe didn't spell it correctly, I was talking about rotating chest to face the net, or past. On one hand, it's pretty common instruction to get chest face forward for flattish faster serves. On other hand, many claims to stay a tad more diagonal to the target even for fastest attempts:
(left is wide slice, right is down the T heater)

I dunno if it's really a thing, believe you could try and report how such alternation works for you 8-B

Ah got it, I think I was taught to face forward but I can try the diagonal thing. If it works for Nick, it's worth trying haha.
