Here are 2 videos. 1 was a good serve and one wasn't. I didn't really jump here bc I was just trying to work on technique and the sun was in my eye/windy. But I used the contential grip and tried to hit up.
But I still cant grasp on how to hit UP on a serve. Especially with this grip.

I just now posted the following in another thread (

but I hope you find it helpful too.
"You liked the video Lukhas posted on "The Upward pitch in the Serve"

"The Serve Doctor" undoubtedly was behind the following video as well, even though Nick narrates it.

I would have you go to 3:07 into the video where the perspective is of a player looking up at the ball.
This is how
YOU should be looking up at the ball if you get a steeper shoulder angle and more knee bend.
Looking up from that steeper shoulder angle and deeper knee bend the ball looks farther away, and it really seems like you
have to hit up to power the ball.
This video explains pretty well the importance of getting more loading from shoulder/hip coiling, a more pronounced bow shape, and more knee bend.
The above body movements are related:
- it is impossible to coil more without bending your knees
- the steep backward lean of the upper body to get a steeper shoulder angle demands that the front hip protrude out further to provide counter balance.
So it is not so much as sticking that hip out there, but of allowing it protrude out for balance so you don't fall backward as you go into a pronounced bow shape.
In keeping with what LeeD said about practice, if you want bigger body movements like in the above video practice your swing without tossing a ball.
Indeed, it is a great idea to practice your new serve motion at home so you can build up some "muscle memory" before hitting the courts where it is all to easy to revert to your former serve.
Once at the court, try doing several serve motions without a toss with your new motion until you are confident you are incorporating all the elements into your serve, and you are able to do so smoothly.
Only then should you actually try serving a ball.
Try taking at least one practice swing before each time you actually do a real serve hitting a ball - otherwise you will quickly fall back to your old serve.
You will have to adjust your toss to your new swing.
But adjust the toss so that the height and placement fit in with your new swing - don't adjust the new swing or develop a hitch to accomodate a new toss.
Good luck!"
