HELP/ADVICE - jumping too much into court on serve

[Blue Beluga]

I have a friend who tries to add more power into his serve by jumping. However, he jumps too much into the court as oppose to more straight up and a little forward. This causes him to hit the ball more behind him, since his body is already way into the court while his toss is only about a foot into the court. He would land with his left foot about two feet pass the baseline. I have tried to correct him so that he lands just pass the baseline or at most a foot pass it, but is is not working. Can some experts/instructors who have had experience with this give me some advice, whether visual, technique, drill, etc. that would help him correct his jumping.

Haha thats funny. There are two ways to fix this. Tell him to toss the ball with more forward motion or tell him instead of jumping, let his body motion throw him forward.

When I first started learning serves, my coach had me serve without moving my feet. I was to create pace by upper body and shoulder rotation.

This really helped me a lot because before I would just jump into the ball and had really bad form, but serving with feet planted and using my upperbody and shoulders really solidified my form and formed a foundation for my actual serve.
I can serve moderataly fast this way, with a single bounce from service box to a low point on fence.

It was after I had gotten this that he brought in the knee bend/bending of back and using that propulsion combined with upper body rotation to produce really explosive serves. (I am still working on this)
The thing is I still keep in mind to keep feet planted, but they will come up a bit as the counter force of the backward bend propels you forward.
I never consciously jump into the ball. I find that this way I hit cleaner better serves.
