Brett Clarke on serving:

Keeping the upper arm stable, and not using too much shoulder... I can really relate to this.
Inspecting my videos, when i serve… which 60% of the time is the pendulum, with side or chop, I’m using a lot of shoulder, but… sometimes I do a reverse pendulum. When I do this, it has way more spin.
I was just shadow-serving that serve, and noticed that the action is much more wrist and elbow, almost no shoulder so the bat is travelling faster, and generating more spin
