shindemac said:ZPTennis, nice serve. This is more an analysis of where the power comes from in your serve, and not a critique. Simple put, you have massive shoulder rotation. Most people who post vids don't even turn their bodies 90 degrees sideways, but you do and more. Plus, you have a very good shoulder stretch. Combined, I would say it gives you most of your power.
It looks effortless because you are loose and able to effectively use the kinetic chain to generate all that power. I don't think your legs are generating as much power as others, but that's just my opinion. It would be amazing if you could get into the 140's by harnessing the energy in your legs. Your serve also looks simple because there are no fancy or wasted movements. It looks like there are only 2 things going on: straighten legs and rotate shoulder while keeping loose.
Erwin said:sweet guys. I've learned more about serving in the last month or so then I ever did. Thanks to Jeff and everyone for their .02.
I like Drakulie's serve as well. Any thoughts on his serve?

Erwin said:yes please do a comparison!
throwing that left hip into the court during the toss? (bending back) or after the hit?
Because it seems like his hip rotates due to his left foot turning in it's heel in a way.
I also notice that the shoulders aren't really rotating into the hit and his followthrough seems stiff. Almost like he's not uncoiling fully.. thoughts??
JCo872 said:Shindemac raises a great point here about the effortless appearance and the kinetic chain. This is why pros look so effortless and average players actually swing a lot more and use a lot more energy without getting much power or pop.
